Sooner or later, virtually all hot stocks implode, said CNBC's Jim Cramer.
And according to him, it's important for investors to know when to cash in before that happens.
By hot stocks, Cramer means speculative companies with relatively low market capitalization that are risky, but have the potential for high reward.
These hot stocks can come out of nowhere, attract more and more attention, but will eventually get tapped out once all of the interested investors have bought shares, he added.
"Eventually everyone who wants a piece of the stock has a piece of it," he said.
