Picks in communication services and industrials also boosted the fund's relative performance.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;The fund's non-benchmark stake in SK Hynix gained approximately 660% and was the top individual relative contributor. This period we decreased our investment in SK Hynix. The second-largest relative contributor was an overweight in Micron Technology (+822%), one of our biggest holdings at period end. Another notable relative contributor was our stake in Marvell Technology (+282%). This period we decreased our investment in the stock.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;In contrast, the biggest detractor from performance versus the benchmark was an underweight in information technology, though it was still only a minor headwind for the portfolio.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;The biggest individual relative detractor was an underweight in Advanced Micro Devices (+309%). This period we increased our investment in Advanced Micro Devices. A second notable relative detractor was an underweight in Sandisk (+957%), a position we established this period. An underweight in Applied Materials (+298%) also detracted. This was an investment we established this period.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;Notable changes in positioning include decreased exposure to the financials and consumer staples sectors.&lt;/span&gt;&lt;/div&gt;
