How these numbers are measured
An oversold episode begins when GOOGL enters an oversold state and ends when it returns to a non-oversold state. Continuous oversold readings are treated as one episode. Overbought episodes are defined the same way.
Episode duration is measured in calendar days. Forward returns are measured 5, 10, 20, 50, and 100 trading days after the first day of each episode. Stock prices are split- and dividend-adjusted.
Historical observations are descriptive and do not predict future performance.
