How to Download Daily Inverse VIX ETF Data for Free on Mac OS X
If you are interested in trading inverse volatility exchange-traded funds (ETFs), you may want to download daily data for these products to analyze their performance and trends. Inverse volatility ETFs are funds that move in the opposite direction of the Cboe Volatility Index (VIX), also known as the market's \"fear gauge\". The VIX measures the expected volatility of the S&P 500 index over the next 30 days, based on the prices of its options. When the VIX rises, it indicates that investors are expecting more uncertainty and turbulence in the market. When the VIX falls, it suggests that investors are more confident and optimistic.
There are several inverse volatility ETFs available in the U.S. market, but they differ in their exposure and methodology. The most popular one is the ProShares Short VIX Short-Term Futures ETF (SVXY), which provides inverse exposure to an index of short-term VIX futures contracts. This means that SVXY aims to move in the opposite direction of the daily changes in the VIX futures curve. Another inverse volatility ETF is the -1x Short VIX Futures ETF (SVIX), which also provides inverse exposure to short-term VIX futures, but with a more targeted approach. SVIX tracks an index that only uses the first two contracts in the VIX futures curve, and rebalances its portfolio at the end of each trading day. Both SVXY and SVIX have a negative correlation with the VIX, meaning that they tend to rise when the VIX falls, and vice versa.
