* Value at Risk (“VaR”) is a measure of the potential loss in value of a portfolio over a defined period for a given confidence interval. A one-day VaR at the 95% confidence level represents that there is a 5% probability that the mark-to-market loss on the portfolio over a one day horizon will exceed this value (assuming normal markets and no trading in the portfolio).

How did the Fund perform and what affected its performance?

 

The ETF returned 1.96% for the twelve months ended January 31, 2026, compared to the Bloomberg US Aggregate Bond Index return of 6.85%.

 

• The U.S. bond market performed well as yields remained high with only slight cuts to the Federal Funds Rate towards the end of the year.  

• The Fund seeks capital appreciation in elevated and rising inflationary environments. Inflation slightly cooled throughout the year, which led to the Fund’s modest performance.
