The Invesco S&P 500 Low Volatility ETF (SPLV) aims to provide investors with exposure to the S&P 500 Low Volatility Index. This fund primarily invests, dedicating at least 90% of its total assets, to the specific securities that make up this benchmark index. The underlying index is overseen and calculated by Standard & Poor's. It comprises 100 stocks selected from the broader S&P 500 Index that have exhibited the lowest price instability, or "realized volatility," over the preceding 12 months. Volatility is essentially a measure of how much an asset's price fluctuates up or down during a given period. Both the ETF and its tracking index undergo systematic rebalancing and constituent adjustments on a quarterly basis, specifically in February, May, August, and November.
