To the extent that NYSE Rule 80A collar, which restricts index arbitrage form of program trading on volatile days, aims to delink S&P 500 cash and futures markets and prevent transmission of volatility from the futures to the cash market, this study finds the collar to be ineffective. The analyses are based on lead-lag regressions for the first and second moments using data diurnalized via a nonparametric filter for intraday volatility periodicity. The regression results also suggest that, consistent with the literature, the futures market has a much stronger tendency to lead the underlying cash market than lag and there is a strong bi-directional lead-lag relationship between volatilities of the two markets, which does not support the assertion that there is a systematic transmission of volatility from the futures to the cash market.
