How can you tell when a company that looks like its business is doing great could be about to lose its mojo?
As you know, Cramer focuses on the fundamentals — how much money it's earning, how much cash it's generating, how fast it's growing. But sometimes, he warns, the fundamentals don't tell the whole story. And that's the case with one Chinese stock.
"This is an ultra, ultra, ultra steamin' high-growth Chinese company," Cramer said. "This has great looking fundamentals, but, this is what's important, it has a hideous, suspicious looking chart."
