NEW YORK ( TheStreet) -- "If you've got a chance to make some money in the market, take it," Jim Cramer told the viewers of his "Mad Money" TV show Thursday as he reflected on a huge up day on Wall Street.

He told investors not to worry about if this rally is sustainable in the future, but rather how they can profit from it today.

Cramer said the Federal Reserve's actions are designed to ignite confidence in the markets. He said they will result in more money coming into the market and thus take stocks higher.

He said the Fed's moves will also trigger buying in the commodities and make the dollar more competitive overseas, all of which leads to profits to be made in the short term.

Cramer likened the current market action to that in Japan in the 1980s, or that of the technology stocks in the 1990s. Yes, both of those moves eventually came to an end, he said, but in the interim fortunes were made.

Cramer said eventually it will be time to take the "money and run," but that time isn't today. He said investors meed to stay flexible, and know when there's still money left on the table and when they've made enough and realize it's time to move on. Cramer's bottom line: "Save the opining for later; there's money to be made."
