“Listed futures on VIX and its cousins give exposure to implied variance. But getting exposure to realised variance is very different and usually has been the realm of OTC variance swaps. Here we examine strategies to trade the realised variance using only listed instruments, with simple time-independent formulas not requiring models such as Black-Scholes.”

“We decompose, within an ARCH framework, the daily volatility of stocks into overnight and intraday contributions. We find, as perhaps expected, that the overnight and intraday returns behave completely differently. For example, while past intra-day returns affect equally the future intraday and overnight volatilities, past overnight returns have a weak effect on future intra-day volatilities (except for the very next one) but impact substantially future overnight volatilities. The exogenous component of overnight volatilities is found to be close to zero, which means that the lion’s share of overnight volatility comes from feedback effects. The residual kurtosis of returns is small for intraday returns but infinite for overnight returns. We provide a plausible interpretation for these findings, and show that our Intraday/Overnight model significantly outperforms the standard ARCH framework based on daily returns for Out-of-Sample predictions.”

“Uncertainty is generally avoided when investing. Volatility is a popular proxy for investment uncertainty, and indeed low volatility stocks outperform high volatility stocks. However, there are also many other possible measures of uncertainty, among which are entropy and the Hurst exponent. Here we show that these measures also predict groups of stocks that outperform.”

“Once upon a time dispersion trading desks used to be the kings (and queens) of volatility trading in the equity arena (if we ignore the 35 mio USD short vega position by LTCM).
“Dispersion desks can handle significant volatility risks in the same way that a basket desk can handle extremely large deltas per instrument or a cap/floor vs. swaption trader can handle extremely large volatility risks per underlying. As a matter of fact, a dispersion trader is essentially a cap/floor vs. swaptions trader, albeit somewhat less structured. Dispersion traders can come into a single stock and sometimes sell signifcant vegas (read: millions) before anyone knows what is happening.”
