The golden rule is - dont believe anything you read on social media. Any post is only ever one person's opinion, and none of us a licensed to give "advice". I refer you to https://hotcopper.com.au/help/code/ which states

Did you take FraserJC's opinion in April 2020 as confirmation to go short, only to get reamed out? If so, you dont understand the market very well. I agreed with FraserJC at the time. The correlation to the DOW in 1929 was almost identical. However no one knew a whole global army of inept Covid investors were going to hit the market, nor that the US Fed's rampant QE progam was going to throw the kitchen sink at the market..

But After those record breaking big moves in Feb/Mar 2020, you'd expect a consolidation period, (blue box). We got that, then a surprise break out (arrow) to the upside . That was your signal to go long. So doesnt matter if someone called it wrong, the charts tell you what to do.

Similalry , after the mad run up on Oct 2021, we had consolidation over Nov/Dec 2021. (blue channel).
Right now , 3950 is crucial for the S&P. After the recent big move down, again, Im expecting some consolidation before it falls thru again.

Prior to Feb 2020 most analysts were expecting a market crash anyway because the global economy was not doing well. The last two years of insanity wont make that go away.
