TheStreet's Jim Cramer says investors shouldn't be making stock trades based on who President-elect Donald Trump is nominating to his Cabinet. Trump has selected Rep. Tom Price, R-Ga., and an Obamacare critic to head the Department of Health and Human Services. Cramer says investors shouldn't be buying stocks such as Stryker (SYK) - Get Report and Zimmer Biomet (ZBH) - Get Report based on the nomination, noting that companies reported weak quarters. "This is a little bit nuts when you see a bunch of stocks go up on an appointment," says Cramer. He said investors should ring the register because he doesn't want people to get hurt.
