The post-election market rally can be attributed to President-elect Donald Trump's vows coming to fruition, CNBC's Jim Cramer said Monday.
"This is a remarkable rally because it's based on everything that this guy says — like anything that Trump said is going to come true." Cramer said on "Squawk on the Street." "And I think that's because people just feel like the Republican Party's going to fall in line."
Major U.S. equity indexes have spiked since Trump's victory over Hillary Clinton in the Nov. 8 election. The Russell 2000 has notched its longest daily winning streak since 1996.
Cramer said some economist predict the Trump rally won't last much longer — but he took a more optimistic view, saying economists need a more solid reason for why it won't last.
"Everybody said two things. One is, this Trump rally can't last. And second, when I ask why not, they say, I don't know. It can't last," he said. "You need something which says it can't last because of 'X.'"
