متن کاملMarket Dynamics And Stock Price Volatility
This paper presents a possible explanation for some of the empirical properties of asset returns within a heterogeneous-agents framework. The model turns out, even if we assume the input fundamental value follows an simple Gaussian distribution lacking both fat tails and volatility dependence, these features can show up in the time series of asset returns. In this model, the profit comparison a...
متن کاملStock price dynamics and option valuations under volatility feedback effect
According to the volatility feedback effect, an unexpected increase in squared volatility leads to an immediate decline in the price–dividend ratio. In this paper, we consider the properties of stock price dynamics and option valuations under the volatility feedback effect bymodeling the joint dynamics of stock price, dividends, and volatility in continuous time. Most importantly, our model pre...
