Popis: We develop a complete-markets model with volatility smiles, tractability, and intuitive appeal as an anchoring or habit-formation model. Like traditional stochastic volatility models, it is invariant to a multiplicative scaling of the stock price levels. The anchoring effect is that the volatility depends on the relative value of the current stock price compared to its past history, with an exponential weighting.
