Methodologies: Heatmaps, Alphalens, Pyfolio
Factor: Volatility
Session returns: Intraday
Time period: 2014/01/01 - 2017/11/06
Idea: Building a long-short strategy depending on the volatility factor assuming that the stocks which are highly volatile will perform bad intraday, while the stocks which are less volatile will perform well intraday => high quantiles are shorted and low quantiles are longed. In here, volatility is defined as volatility of daily returns (the annualized standard deviations of the last 20 days). This strategy goes against the idea "Higher risks, higher returns", which could be beneficial for risk adverse investors.
Heatmaps: Intraday returns drop significantly (0-9q). In lower quantiles, there more positive returns than in higher quantiles. The number of observations tend to concentrate on the inverse diagonal of the heatmap.
