It's price discovery. So, yes it is frequently wrong on the way to being right, then wrong again reversing to be right.
The market does not lose money. Nor does it gain. The market is where/when things are transacted: you voluntarily pay $10 for something that was sold to you by a party that wished to receive $10 for it. For that transaction, one party received a $10 good/service, while the other party received $10. Per transaction, the market on moves the value. No right or wrong about it.
You often hear the cliche; "The markets are never wrong". Because it is bandied around so often and accepted by so many doesn't make it correct. If the majority of traders lose money trading, it can then be surmised they are wrong. If the majority mass of traders drive the market (with emotions/sentiment), then clearly there is a problem. Further, as humans are sheep and most seem the believe in some form of TA for their beliefs, and they are wrong via losing money, we can deduct the following: mass of traders losing money, following other losers, driving a market on false beliefs in the wrong direction using faulty analysis means more money for those few who get it right.
I made $ trading inverses February March selloff, and lost it trying to bottomfish them ever since because I thought the market was wrong to rally during catastrophic pandemic. A double fckup swing trading bc I didn't benefit much from March til now rally. I'm better daytrading vs swingtrading. I still believe the market is way overbought and may crash sub 3k. But as hafez wisely said, trade what you see, not what you think.
Such a nice looking doggy!!!! Is that a bull dog or bear dog Always remember: The market can remain irrational longer than you can remain solvent
