If you're relatively new to the market, there's something Jim Cramer doesn't want you to do. He doesn't even want you to think about it.
Under no circumstances should individual investors use market orders.
Unfortunately, all too many people who are new to the stock market don't even know what that means.
"When you call your broker and tell him to buy or sell a stock, but you don't name a price, that's a market order," explained the "Mad Money" host. "You may not realize it, but what you're doing is giving that broker permission to fill your order at any price."
When explained that way, Cramer said, of course you wouldn't place a market order.
"Would you go at supermarket and say I'll buy a head of lettuce at any price? Would you do that with a sweater at the mall? No, of course not," Cramer said.
However, it happens all too often when people go shopping for stocks simply because new investors don't know any better.
