"Losing stocks can become a winner again when bold management makes informed decisions and cheats the ball," he said. "I think it's an important story because it shows you how companies that have been depreciated and left for dead can, in effect, become relevant again if they have excellent management."

Sam Adams, Boston Beer's flagship brand, recorded double-digit growth of 27% in the early 2010s, as smaller smaller breweries open their doors across the country and begin to attract # 39; s attention. Sam Adams' growth slowed dramatically in 2015, followed by two years of declines. Cramer said that he had abandoned this activity when the stock had collapsed.

During an April teleconference, Burwick told shareholders: "The growth of our company really exceeds our expectations, we are expanding distribution across all channels and improving our leadership position in the selectors sector. as more and more competitors enter the category. "

"That's what makes the return of Boston Beer so amazing," Cramer said. It's risky, but "Boston Beer understands that you can only be a growing business if you're ready to spend money to improve your business."

Last week, Guggenheim increased his price target to $ 421, predicting more years of profitable growth thanks to Truly.

Cramer thinks that stocks are too expensive and are trading 39 times more than next year 's earnings estimates, but a buying opportunity could loom on the horizon.
