Factors Affecting Performance [Text Block] |
|
How did the Fund perform last year?For the reporting period ended July 31, 2025, the Fund returned 7.29%. For the same period, the Bloomberg U.S. Universal Index returned 4.00% and the MSCI All Country World Index (Net) returned 15.87%.
What contributed to performance? U.S. large-capitalization equities were the largest contributor to the Fund’s return during the reporting period. In particular, semiconductor stocks gained amid continued demand for artificial intelligence (“AI”) and generative AI workloads in data centers, while systems software firms benefited from strong growth in their respective cloud businesses and increasing adoption of AI technologies. International developed stocks, particularly in Germany, gained amid optimism surrounding a historic fiscal stimulus plan targeting infrastructure and defense spending. Within the bond allocation, longer-dated U.S. dollar-denominated bonds contributed. What detracted from performance? During the reporting period, there were no meaningful detractors from the Fund’s return. The views expressed reflect the opinions of BlackRock as of the date of this report and are subject to change based on changes in market, economic or other conditions. These views are not intended to be a forecast of future events and are no guarantee of future results.

Factors Affecting Performance [Text Block] |
|
How did the Fund perform last year?For the reporting period ended July 31, 2025, the Fund returned 8.38%. For the same period, the Bloomberg U.S. Universal Index returned 4.00% and the MSCI All Country World Index (Net) returned 15.87%.
What contributed to performance? U.S. large-capitalization equities were the largest contributor to the Fund’s return during the reporting period. In particular, semiconductor stocks gained amid continued demand for artificial intelligence (“AI”) and generative AI workloads in data centers, while systems software firms benefited from strong growth in their respective cloud businesses and increasing adoption of AI technologies. International developed stocks, particularly in Germany, gained amid optimism surrounding a historic fiscal stimulus plan targeting infrastructure and defense spending. Within the bond allocation, longer-dated U.S. dollar-denominated bonds contributed. What detracted from performance? During the reporting period, there were no meaningful detractors from the Fund’s return. The views expressed reflect the opinions of BlackRock as of the date of this report and are subject to change based on changes in market, economic or other conditions. These views are not intended to be a forecast of future events and are no guarantee of future results.

Factors Affecting Performance [Text Block] |
|
How did the Fund perform last year?For the reporting period ended July 31, 2025, the Fund returned 10.58%. For the same period, the MSCI All Country World Index (Net) returned 15.87% and the Bloomberg U.S. Universal Index returned 4.00%.
What contributed to performance? U.S. large-capitalization equities were the largest contributor to the Fund’s return during the reporting period. In particular, semiconductor stocks gained amid continued demand for artificial intelligence (“AI”) and generative AI workloads in data centers, while systems software firms benefited from strong growth in their respective cloud businesses and increasing adoption of AI technologies. International developed stocks, particularly in Germany, gained amid optimism surrounding a historic fiscal stimulus plan targeting infrastructure and defense spending. Within the bond allocation, longer-dated U.S. dollar-denominated bonds contributed. What detracted from performance? During the reporting period, there were no meaningful detractors from the Fund’s return. The views expressed reflect the opinions of BlackRock as of the date of this report and are subject to change based on changes in market, economic or other conditions. These views are not intended to be a forecast of future events and are no guarantee of future results.

Factors Affecting Performance [Text Block] |
|
How did the Fund perform last year?For the reporting period ended July 31, 2025, the Fund returned 12.74%. For the same period, the MSCI All Country World Index (Net) returned 15.87% and the Bloomberg U.S. Universal Index returned 4.00%.
What contributed to performance? U.S. large-capitalization equities were the largest contributor to the Fund’s return during the reporting period. In particular, semiconductor stocks gained amid continued demand for artificial intelligence (“AI”) and generative AI workloads in data centers, while systems software firms benefited from strong growth in their respective cloud businesses and increasing adoption of AI technologies. International developed stocks also contributed. German stocks were driven by strong corporate earnings and optimism surrounding a historic fiscal stimulus plan targeting infrastructure and defense, which supported firms in the industrials space. Emerging-market equities also contributed, especially Chinese stocks, which benefited from the country's historic stimulus packages; the country’s interactive media and services stocks were supported by AI powered innovation and investments. What detracted from performance? During the reporting period, there were no meaningful detractors from the Fund’s return. The views expressed reflect the opinions of BlackRock as of the date of this report and are subject to change based on changes in market, economic or other conditions. These views are not intended to be a forecast of future events and are no guarantee of future results.

Factors Affecting Performance [Text Block] |
|
How did the Fund perform last year?For the reporting period ended July 31, 2025, the Fund returned 7.20%. For the same period, the Bloomberg U.S. Universal Index returned 4.00% and the MSCI All Country World Index (Net) returned 15.87%.
What contributed to performance? U.S. dollar-denominated high-yield corporate securities were the largest contributors to the Fund’s return during the reporting period, helped by healthy underlying fundamentals and the improved composition of the high yield bond market. International developed stocks also contributed, notably, value-oriented companies within the financial sector. In Germany, stocks were driven by strong corporate earnings from global-facing companies. Insurance names were supported by growth across business lines, while diversified capital markets companies benefited from strong trading volume and solid investment banking revenue. Within the bond allocation, shorter-term, floating rate issues gained as the Federal Reserve lowered interest rates several times during the reporting period. What detracted from performance? During the reporting period, there were no meaningful detractors from the Fund’s return. The views expressed reflect the opinions of BlackRock as of the date of this report and are subject to change based on changes in market, economic or other conditions. These views are not intended to be a forecast of future events and are no guarantee of future results.

Factors Affecting Performance [Text Block] |
|
How did the Fund perform last year?For the reporting period ended July 31, 2025, the Fund returned 6.16%. For the same period, the MSCI USA Index returned 16.96% and the MSCI USA Minimum Volatility Extended ESG Reduced Carbon Target Index returned 6.34%.
What contributed to performance? Stocks in the information technology sector were the leading contributors to the Fund’s return during the reporting period. Systems software firms benefited from strong growth in their respective cloud businesses and increasing adoption of artificial intelligence (“AI”) technologies. Application software companies, spanning chip designers and industrial and financial software innovators, contributed as they accelerated their AI-driven monetization through AI-native tools and platform enhancements. In the technology hardware space, communications equipment stocks gained as they leveraged artificial intelligence to automate network management, enhance product capabilities, and deliver more efficient and intelligent solutions to enterprise and consumer markets. In the industrials sector, firms in the aerospace and defense segment experienced positive momentum due to increased defense spending, while building products companies benefited from strong demand for cooling systems in data centers. What detracted from performance? Healthcare stocks detracted from the Fund’s return during the reporting period, as the sector was increasingly pressured by regulatory scrutiny and policy upheaval. Managed healthcare firms faced additional challenges due to rising utilization and medical costs, as well as changes in reimbursement levels. The views expressed reflect the opinions of BlackRock as of the date of this report and are subject to change based on changes in market, economic or other conditions. These views are not intended to be a forecast of future events and are no guarantee of future results.

Factors Affecting Performance [Text Block] |
|
How did the Fund perform last year?For the reporting period ended July 31, 2025, the Fund returned 8.16%. For the same period, the MSCI USA Index returned 16.96% and the MSCI USA Minimum Volatility Index returned 8.31%.
What contributed to performance? During the reporting period, stocks in the information technology sector, especially in the technology hardware space, were the leading contributors to the Fund’s return. These companies leveraged artificial intelligence (“AI”) to automate network management, enhance product capabilities, and deliver more efficient and intelligent solutions to enterprise and consumer markets. Meanwhile, systems software firms benefited from strong growth in their respective cloud businesses and increasing adoption of AI technologies. Stocks in the financials sector were also notable contributors. Firms in the financial exchanges and data segment were supported by new product launches, as well as an increase in trading volume and volatility, while transaction and payment processing services companies gained amid a surge in cross-border transactions and the growing adoption of digital payments. Further, property and casualty insurance names benefited from premium growth and improved underwriting results. What detracted from performance? The largest detractors from the Fund’s return during the reporting period were in the healthcare sector, as it faced increasing pressure from regulatory scrutiny and policy upheaval. Managed healthcare firms were subject to additional challenges due to rising utilization and medical costs, as well as changes in reimbursement levels. The views expressed reflect the opinions of BlackRock as of the date of this report and are subject to change based on changes in market, economic or other conditions.

Factors Affecting Performance [Text Block] |
|
How did the Fund perform last year?For the reporting period ended July 31, 2025, the Fund returned 27.63%. For the same period, the MSCI USA Index returned 16.96% and the MSCI USA Momentum SR Variant Index (Spliced) returned 27.85%.
What contributed to performance? During the reporting period, stocks in the information technology sector were the leading contributors to the Fund’s return. Application software companies benefited from their exposure to artificial intelligence (“AI”) and digital transformation themes. In particular, a company specializing in data analysis and AI experienced robust growth across its government and commercial sectors. In addition, semiconductor stocks gained amid continued demand for AI and generative AI, data center expansions, and continued innovation in chips and network solutions. In the industrials sector, aerospace and defense stocks gained amid robust demand for engines and services in commercial aviation, as well as government support for defense spending. Additionally, electrical equipment manufacturers benefited as the growth of AI data centers dramatically increased electricity demand. Stocks in the financials sector were also notable contributors, benefiting from resilient equity markets, rising assets under management, strong trends in wealth management, and high trading volumes. What detracted from performance? There were no meaningful detractors from the Fund’s performance during the reporting period. The views expressed reflect the opinions of BlackRock as of the date of this report and are subject to change based on changes in market, economic or other conditions. These views are not intended to be a forecast of future events and are no guarantee of future results.

Factors Affecting Performance [Text Block] |
|
How did the Fund perform last year?For the reporting period ended July 31, 2025, the Fund returned 8.31%. For the same period, the MSCI USA Index returned 16.96% and the MSCI USA Sector Neutral Quality Index (Spliced) returned 8.47%
What contributed to performance? Stocks in the communications sector were among the leading contributors to the Fund’s return during the reporting period. Notably, firms in the interactive media and services segment were supported by solid digital advertising revenue growth fueled by artificial intelligence (“AI”) investments that improved ad targeting and performance. In the information technology sector, systems software firms benefited from strong demand in cloud-delivered businesses, while semiconductor stocks gained amid unprecedented demand for AI and generative AI, data center expansions, and continued innovation in chips and network solutions. Further, communications equipment companies leveraged AI to automate network management, enhance product capabilities, and deliver more efficient and intelligent solutions to enterprise and consumer markets. Transaction and payment processing firms in the financials sector were supported by cross-border transactions and the growing adoption of digital payments. What detracted from performance? U.S. healthcare stocks were modest detractors from the Fund’s return during the reporting period, pressured by increasing regulatory scrutiny and policy upheaval. Managed healthcare firms faced additional challenges due to rising utilization and medical costs, as well as changes in reimbursement levels. The views expressed reflect the opinions of BlackRock as of the date of this report and are subject to change based on changes in market, economic or other conditions. These views are not intended to be a forecast of future events and are no guarantee of future results.

Factors Affecting Performance [Text Block] |
|
How did the Fund perform last year?For the reporting period ended July 31, 2025, the Fund returned 10.86%. For the same period, the MSCI USA Index returned 16.96% and the MSCI USA Low Size Index (Spliced) returned 11.06%.
What contributed to performance? Application software stocks in the information technology sector contributed to the Fund’s performance during the reporting period. Notable contributors included a company specializing in data analysis and artificial intelligence (“AI”), which experienced significant growth in its government and commercial sectors and a firm that provides solutions for in-app advertising, mobile device marketing, and connected TV advertising. Meanwhile, increased demand for consumer electronics, such as smartphones, laptops, and smart appliances, has fueled the companies that manufacture the building blocks for these products in the electronic equipment, instruments, and components firms segment. Stocks in the financials sector were also notable contributors, benefiting from resilient equity markets, rising assets under management, strong trends in wealth management, and high trading volumes. In the industrials sector, aerospace and defense stocks gained amid robust demand for engines and services in commercial aviation, as well as government support for defense spending. Electrical equipment manufacturers benefited as the growth of AI data centers dramatically increased electricity demand. What detracted from performance? U.S. healthcare stocks were modest detractors from the Fund’s return during the reporting period, pressured by increasing regulatory scrutiny, tariff threats, and policy upheaval. The views expressed reflect the opinions of BlackRock as of the date of this report and are subject to change based on changes in market, economic or other conditions. These views are not intended to be a forecast of future events and are no guarantee of future results.

Factors Affecting Performance [Text Block] |
|
How did the Fund perform last year?For the reporting period ended July 31, 2025, the Fund returned 7.93%. For the same period, the MSCI USA Index returned 16.96% and the MSCI USA Enhanced Value Index (Spliced) returned 8.11%.
What contributed to performance? Stocks in the financials sector were the most significant contributors to the Fund’s performance during the reporting period, benefiting from resilient equity markets, rising assets under management, strong trends in wealth management, and high trading volumes. As diversified banks experienced improved profitability and demonstrated resilience, they raised dividends and announced share buybacks, providing an additional boost. Also contributing were companies within the communications equipment space in the information technology sector. These firms leveraged artificial intelligence (“AI”) to automate network management, enhance product capabilities, and deliver more efficient and intelligent solutions to enterprise and consumer markets. Within the IT services segment, a technology company benefited from its business shift which included strategic investments in AI, hybrid cloud, and software. Further, strong subscriber growth and fiber network expansion supported a large telecommunications company in the communication sector. What detracted from performance? U.S. healthcare stocks modestly detracted from the Fund’s return during the reporting period, as they faced increased regulatory scrutiny and policy upheaval. Managed healthcare firms faced additional challenges due to rising utilization and medical costs, as well as changes in reimbursement levels. The views expressed reflect the opinions of BlackRock as of the date of this report and are subject to change based on changes in market, economic or other conditions. These views are not intended to be a forecast of future events and are no guarantee of future results.

Factors Affecting Performance [Text Block] |
|
How did the Fund perform last year?For the reporting period ended July 31, 2025, the Fund returned 8.25%. For the same period, the Bloomberg U.S. Aggregate Bond Index returned 3.38% and the Russell 1000® Index returned 16.54%.
What contributed to performance? During the reporting period, equity markets registered solid gains, outperforming the modest gains of fixed-income securities. Across the LifePath® vintages, information technology stocks in the U.S. large-capitalization space were the largest driver of returns. Semiconductor stocks gained amid unprecedented demand for artificial intelligence (“AI”) and generative AI, data center expansions, and continued innovation in chips and network solutions, while systems software firms benefited from strong growth in their respective cloud businesses and increasing adoption of AI technologies. Stocks in the financials sector were also notable contributors, benefiting from resilient equity markets, rising assets under management, strong trends in wealth management, and high trading volumes. International developed stocks also benefited performance. Optimism surrounding a historic fiscal stimulus plan targeting infrastructure and defense supported firms in the German industrials space. The bond allocation also gained during the reporting period. For the retirement and earlier-dated vintages, inflation-protected securities rose as pricing pressures remained elevated and tariff uncertainty raised future pricing expectations. What detracted from performance? Given the strength of equity and bond markets during the reporting period, there were no material detractors to the performance of any of the vintages. The views expressed reflect the opinions of BlackRock as of the date of this report and are subject to change based on changes in market, economic or other conditions. These views are not intended to be a forecast of future events and are no guarantee of future results.

Factors Affecting Performance [Text Block] |

How did the Fund perform last year?For the reporting period ended July 31, 2025, the Fund returned 9.62%. For the same period, the Russell 1000® Index returned 16.54% and the Bloomberg U.S. Aggregate Bond Index returned 3.38%.
What contributed to performance? During the reporting period, equity markets registered solid gains, outperforming the modest gains of fixed-income securities. Across the LifePath® vintages, information technology stocks in the U.S. large-capitalization space were the largest driver of returns. Semiconductor stocks gained amid unprecedented demand for artificial intelligence (“AI”) and generative AI, data center expansions, and continued innovation in chips and network solutions, while systems software firms benefited from strong growth in their respective cloud businesses and increasing adoption of AI technologies. Stocks in the financials sector were also notable contributors, benefiting from resilient equity markets, rising assets under management, strong trends in wealth management, and high trading volumes. International developed stocks also benefited performance. Optimism surrounding a historic fiscal stimulus plan targeting infrastructure and defense supported firms in the German industrials space. The bond allocation also gained during the reporting period. For the retirement and earlier-dated vintages, inflation-protected securities rose as pricing pressures remained elevated and tariff uncertainty raised future pricing expectations. What detracted from performance? Given the strength of equity and bond markets during the reporting period, there were no material detractors to the performance of any of the vintages. The views expressed reflect the opinions of BlackRock as of the date of this report and are subject to change based on changes in market, economic or other conditions.

Factors Affecting Performance [Text Block] |
|
How did the Fund perform last year?For the reporting period ended July 31, 2025, the Fund returned 12.96%. For the same period, the Russell 1000® Index returned 16.54% and the Bloomberg U.S. Aggregate Bond Index returned 3.38%.
What contributed to performance? During the reporting period, equity markets registered solid gains, outperforming the modest gains of fixed-income securities. Across the LifePath® vintages, information technology stocks in the U.S. large-capitalization space were the largest driver of returns. Semiconductor stocks gained amid unprecedented demand for artificial intelligence (“AI”) and generative AI, data center expansions, and continued innovation in chips and network solutions, while systems software firms benefited from strong growth in their respective cloud businesses and increasing adoption of AI technologies. Stocks in the financials sector were also notable contributors, benefiting from resilient equity markets, rising assets under management, strong trends in wealth management, and high trading volumes. International developed stocks also benefited performance. Optimism surrounding a historic fiscal stimulus plan targeting infrastructure and defense supported firms in the German industrials space. The bond allocation also gained during the reporting period. For the retirement and earlier-dated vintages, inflation-protected securities rose as pricing pressures remained elevated and tariff uncertainty raised future pricing expectations. What detracted from performance? Given the strength of equity and bond markets during the reporting period, there were no material detractors to the performance of any of the vintages. The views expressed reflect the opinions of BlackRock as of the date of this report and are subject to change based on changes in market, economic or other conditions. These views are not intended to be a forecast of future events and are no guarantee of future results.

Factors Affecting Performance [Text Block] |
|
How did the Fund perform last year?For the reporting period ended July 31, 2025, the Fund returned 14.71%. For the same period, the Russell 1000® Index returned 16.54% and the Bloomberg U.S. Aggregate Bond Index returned 3.38%.
What contributed to performance? During the reporting period, equity markets registered solid gains, outperforming the modest gains of fixed-income securities. Across the LifePath® vintages, information technology stocks in the U.S. large-capitalization space were the largest driver of returns. Semiconductor stocks gained amid unprecedented demand for artificial intelligence (“AI”) and generative AI, data center expansions, and continued innovation in chips and network solutions, while systems software firms benefited from strong growth in their respective cloud businesses and increasing adoption of AI technologies. Stocks in the financials sector were also notable contributors, benefiting from resilient equity markets, rising assets under management, strong trends in wealth management, and high trading volumes. International developed stocks also benefited performance. Optimism surrounding a historic fiscal stimulus plan targeting infrastructure and defense supported firms in the German industrials space. The bond allocation also gained during the reporting period. For the retirement and earlier-dated vintages, inflation-protected securities rose as pricing pressures remained elevated and tariff uncertainty raised future pricing expectations. What detracted from performance? Given the strength of equity and bond markets during the reporting period, there were no material detractors to the performance of any of the vintages. The views expressed reflect the opinions of BlackRock as of the date of this report and are subject to change based on changes in market, economic or other conditions. These views are not intended to be a forecast of future events and are no guarantee of future results.

Factors Affecting Performance [Text Block] |
|
How did the Fund perform last year?For the reporting period ended July 31, 2025, the Fund returned 14.82%. For the same period, the Russell 1000® Index returned 16.54% and the Bloomberg U.S. Aggregate Bond Index returned 3.38%.
What contributed to performance? During the reporting period, equity markets registered solid gains, outperforming the modest gains of fixed-income securities. Across the LifePath® vintages, information technology stocks in the U.S. large-capitalization space were the largest driver of returns. Semiconductor stocks gained amid unprecedented demand for artificial intelligence (“AI”) and generative AI, data center expansions, and continued innovation in chips and network solutions, while systems software firms benefited from strong growth in their respective cloud businesses and increasing adoption of AI technologies. Stocks in the financials sector were also notable contributors, benefiting from resilient equity markets, rising assets under management, strong trends in wealth management, and high trading volumes. International developed stocks also benefited performance. Optimism surrounding a historic fiscal stimulus plan targeting infrastructure and defense supported firms in the German industrials space. The bond allocation also gained during the reporting period. For the retirement and earlier-dated vintages, inflation-protected securities rose as pricing pressures remained elevated and tariff uncertainty raised future pricing expectations. What detracted from performance? Given the strength of equity and bond markets during the reporting period, there were no material detractors to the performance of any of the vintages. The views expressed reflect the opinions of BlackRock as of the date of this report and are subject to change based on changes in market, economic or other conditions. These views are not intended to be a forecast of future events and are no guarantee of future results.
