Sell Signals All but Useless in Unchartable 2021 Stock Market

If you bailed because of Bollinger Bands, ran away from relative strength or took direction from the directional market indicator in 2021, you paid for it.

It’s testament to the straight-up trajectory of stocks that virtually all signals that told investors to do anything but buy have done them a disservice this year. In fact, when applied to the S&P 500, 15 of 22 chart-based indicators tracked by Bloomberg have actually lost money, back-testing data show. And all are doing worse than a simple buy-and-hold strategy, which is up 11%.
