hedge funds and swap dealers relate to volatility and price changes. Examining various subperiods where price trends are … discovery by trading with contemporaneous returns while serving to reduce volatility. Swap dealer activity, however, is largely … unrelated to both contemporaneous returns and volatility. Our evidence is consistent with the hypothesis that hedge funds …

We study measures of foreign exchange rate volatility based on high-frequency (5-minute) $/DM exchange rate returns … using recent nonparametric statistical techniques to compute realized return volatility and its separate continuous sample … implied volatility. We find that implied volatility is an informationally efficient but biased forecast of future realized …

We investigate the potential forecasting role of … implied volatility backed out from option prices in the presence of these new separate realized volatility components. We show …

We develop a discrete-time affine stochastic volatility model with time-varying conditional skewness (SVS). Importantly …, we disentangle the dynamics of conditional volatility and conditional skewness in a coherent way. Our approach allows …
