'It Is Too Sizzling For Me': Why Jim Cramer Isn't Buying This 'Red Hot' Group Of Stocks.

$Kelly Services-A (KELYA.US)$ $PepsiCo (PEP.US)$ $Mirum Pharmaceuticals (MIRM.US)$ On CNBC’s "Mad Money Lightning Round," Jim Cramer said Kelly Services, Inc. is a "very well-run company. Right now, with people just feeling it’s easy to get a job, you don’t need them. That’s why that stock has been such a dog. You never know, but I am not a buyer of it right here, though."

When asked about PepsiCo, Inc. , Cramer said, "I just wish the stock would come down. It doesn’t seem to want to come down at all, but it is well run and terrific."
