about the lecture:
this study develops a prevailing shrinkage method, lasso with a markov regime-switching model (mrs-lasso), to predict us stock market volatility. in total, 17 well-known macroeconomic and financial factors are used in this research. the out-of-sample results reveal that the mrs-lasso model can successfully predict volatility from statistical and economic viewpoints. we further investigate the predictability of mrs-lasso in terms of the different market conditions, business cycles, and variable selection. three factors (equity market returns, short-term reversal factor, and consumer sentiment index) are the most frequent predictors. to investigate the practical implications, we construct the expected variance risk premium (vrp) by using volatility forecasts generated from the lasso and mrs-lasso models to forecast future stock returns and find that those models are also powerful.
