The document discusses a strategy for beating the market with less risk by avoiding the worst performing days. It notes that the best days often follow the worst days, which tend to occur during periods of high volatility like bear markets. The strategy presented is to own the S&P 500 only when it is above its 200-day moving average, and own bonds instead (AGG) when it is below. Backtesting shows this strategy would have captured 47 of the 50 best and worst days since 1997 simply by following this rule. The strategy is presented as having fewer trades than actively trading and avoiding human errors like missing trades or trading the wrong size.
