Even though CNBC's Jim Cramer always tells investors to buy stocks when they decline because of some unrelated event that shakes the market, he knows they don't always do it.
"Today, after Sen. Marco Rubio said he can't vote for the new tax bill and other Republican senators might be balking too, the market took a hit... how many of you took this moment and treated it as a buying opportunity? I'm betting most of you didn't," the "Mad Money" host said.
But if you think that a hiccup in the GOP's tax overhaul plans could truly derail the bull market, you might be wrong, Cramer said.
Disney's deal to buy $52 billion worth of Twenty-First Century Fox's entertainment assets, announced Thursday, is a glaring example of a company helping itself, Cramer said.
And, if the deal is approved by regulatory authorities, both stocks are "buyable" on its prospects, Cramer said.
