We study a segmented-markets setting in which self-fulfilling volatility can arise. The only requirements are (i) asset … valuation ratios stationary (e.g., cash flow growth rises when valuations rise). We prove that when self-fulfilling volatility … susceptible to self-fulfilling fluctuations. The tight theoretical connection between price volatility and arbitrage is detectable …

We identify a global risk factor in the cross-section of implied volatility returns in currency markets. A zero …-cost strategy that buys forward volatility agreements with downward sloping implied volatility curves and sells those with upward … slopes - volatility carry strategy - generates significant excess returns. The covariation with volatility carry returns …

We propose a detailed survey of recent volatility models, accounting for multiple … stochastic volatility model families and often borrow methodological tools from statistical physics.
