Recommend a strategy that all US stock traders understand: it's not about a high win rate, but one that has been 100% historically backtested with verifiable results—everyone who uses it knows:

Every time CNBC airs a special program called Markets in Turmoil, the S&P 500's one-year return is 100%, with an average return of +40%.
There's also a strategy with a 95.8% win rate: buy the S&P when the VIX fear index is above 35, and sell when it's below 15.
