Our studies have consistently shown thatin high and high underlyings outperforms selling in low IV and low IVR underlyings. We’ve observed that an index ETF will have a lower IV than its individual stock components. Is it accurate that ETFs have a lower IV than the individual stocks that comprise it and does this mean that we should be trading options on the individual stocks instead?
A graph plotted the XLF (Financial ETF) and XLU (Utilities ETF) along with some of their component stocks for IVR by IV. We prefer underlyings that are in the top right of the graph which means high IV and IVR. Both ETFs were in the lower left area while their individual stocks were in a more favorable area. A separate graph of the distribution curves of theirdemonstrated that individual stocks have had more outlier moves than ETFs over the last several years. ETFs are less vulnerable to large moves driven by news, and events due to their diversification.
A table comparing average bid/ask spreads of the at-the-money (ATM) options in the XLF & XLU and 3 of their top holdings was displayed. The table showed that the ETFs tend to have betterthan their holdings. We believe in the importance of liquidity so much that we have a liquidity indicator on the platform. The edge from higher volatility can quickly disappear due to lower liquidity.
