Markets are always the same, they always change.

The only constant when it comes to markets is change. Quantitative easing, or QE, was one of a number of material changes introduced to the markets which destroyed a number of variables that had once carried predictive value. Thus being able to pivot in a timely manner has always been critical to the few successful investors who have remained successful.  If we analyze a century worth of data, we will see that all crises were followed by major averages bottoming then moving higher which brought major buying opportunities.

Note: While markets have always recovered, it can take many years, sometimes decades, to breakeven if you bought at a peak.
