Cramer Remix: Beware the Fed’s impact here
Cramer Remix: Beware the Fed’s impact here · CNBC

After bottoming on Feb. 11, stocks have had an enormous run in the past few weeks. What was so special about that day? It was the day JPMorgan (NYSE: JPM) CEO Jamie Dimon bought 500,000 shares of his company's stock.

Jim Cramer now calls this day the "Jamie Dimon bottom."

Cramer knows that Dimon did not intend to call a bottom that day, but not only is JPMorgan up more than 7 percent since then, but the Dow (Dow Jones Global Indexes: .DJI) and S&P 500 (INDEX: .SPX) have both rallied higher.

"This well-timed buy had more to do with the prevailing gloom three-and-a-half weeks ago than the actual conditions at his bank," the "Mad Money" host said.

It was a combination of various factors that all came together to allow the averages to roar higher. One of those factors was the Fed, as. Janet Yellen was testifying at the exact same time the market bottomed. Her testimony only accelerated the view that the Fed saw the weakness occurring but wasn't necessarily willing to stop its course of tightening.

Cramer has a position of Bank of America in his charitable trust, because he thought there would be two rate hikes coming from the Fed. He added that without rate hikes, this stock is not in good shape. But with the rate hikes, it is. He thinks the binary nature of the stock has prompted it to fall to $13 from $15.

Suddenly, the market has embraced everything it hated just a few weeks ago, especially the speculative stocks of commodity-based companies. Cramer boiled the rally down to the bold moves of commodity players issuing secondary offerings.

While the rally began with a tremendous amount of short-sellers covering positions, Cramer thinks it is the secondary offerings is what saved the day. While the offerings can be dilutive — meaning that when the earnings come back, each share will make less —but Cramer saw an upside, too.

"The beautiful thing here is that the company will live to play again, even in a scenario where oil prices stay lower longer," the "Mad Money" host said.

Considering the way these companies have managed to stay afloat with the secondaries, it could mean that the worst is over for commodity stocks that have moved above the $2 to $3 range.

"Just like the banks did massive equity offerings in the bad old days of the Great Recession, they, too, got saved. This is the same thing," Cramer said.

And when it comes to earnings, Cramer reminded investors that sometimes a disappointment doesn't really disappoint.
