One of the most dangerous myths of the stock market, according to Jim Cramer, is that the action always makes sense.
"On any given day, the action in the market can be completely nonsensical. Stocks can go up when they should have gone down and vice versa. Entire sectors can move for totally bogus reasons," the "Mad Money" host said.
Cramer reminded investors to never forget that the market can often be stupid for entire sessions of trading. Sometimes this is evident in the media, where explanations are created when there are none in an attempt to find logic and reason behind the moves.
