What sort of evidence or indicators will there be to tell you that the bottom of this market correction has been reached?

Or can the bottom really only be identified in hindsight?

I assume everyone and their mother’s is trying to identify when the stock market or major indices have reached the bottom of this current decline and will begin to rebound.

My question is not about timing the market per se, but rather a question about what, if any, pieces of evidence or indicators may show us that the bottom has been reached. Is there anything that we can learn from historical market corrections that maybe can guide us in identifying this.

For example, if you were to see three or four consecutive green days in the S&P 500, would that be enough to make you feel like things are behind us? What about if the S&P 500 were to close 5% above its year-to-date lows? Would that be enough to convince you? Obviously these are just examples that I’m giving, I’m not a financial expert, but I am interested in learning if there are other tools that may help in this.
