The Invesco S&P International Developed Low Volatility ETF aims to mirror the performance of the S&P BMI International Developed Low Volatility Index. This ETF typically commits at least 90% of its total assets to the securities found within its benchmark index. S&P Dow Jones Indices develops and maintains this index, which evaluates the actual price volatility of its 200 component stocks over the preceding 12 months. Its construction assigns greater weight to stocks exhibiting lower historical fluctuations. The index's calculations use net returns, factoring in tax deductions for non-resident investors. Volatility, in essence, is a statistical measure of how much an asset's price fluctuates over time. Both the fund and its underlying index are rebalanced and reconstituted every quarter.
