Where there any futures contracts traded on the CBOE S&P 100 Volatility Index (VXO) in the 1980s and/or 1990s? I've been searching various corners of the internet (including some historical data providers) but haven't been able to find anything definitive. My guess is that there weren't, but perhaps someone knows and can put me out of my google-searching misery!
Probably hard to get or wildly expensive, but CBOE research modeled back to 1980ish. One of the old annual reports had it. It was used as a selling tool to show the impact of the 87 market break.
