CNBC’s Jim Cramer on Wednesday offered investors a list of bull markets he’s identified as companies report quarterly financial results. “Now that we are already one-fifth of the way through earnings season, we can start identifying the winners and losers,” he said, adding, “We have some legitimate, sizable bull markets going on here, and they show no signs of letting up.
