In his 30-year career in the markets, Cramer said he's seen more dishonesty from the short-sellers than he ever has from the bulls. He said there are just as many people trying to push the markets down as there are trying to drive them higher.
In fact, while most commentators will disclose they own a stock when they talk about it on TV, Cramer said they always fail to mention if they're looking for a better entry point into that stock.
Cramer explained that hedge funds, in particular, cannot afford to underperform the markets or their peers. So if a fund is underinvested or is lagging its peers, a broad market decline is just what's needed to get back on track.
Cramer said it would be a wonderful world if everyone was honest. Since that's not the case, it's important to know what to watch out for."Always be on guard," said Cramer. "People badmouthing the markets aren't any more honest than those who tout specific stocks."
