Cramer: Why Best Buy needs a 'big reset'

A steady stream of positive analyst notes before the busy holiday season helped set up Best Buy for its huge 30 percent drop Thursday, CNBC's Jim Cramer said.

"Each day one came out and then another came out," Cramer said Thursday on "Squawk on the Street." "If they had all come out at once, the stock wouldn't have been pumped to where it was. It was a serial rollout of positives."

Best Buy shares tanked on Thursday after the company reported disappointing sales and revenue during the important holiday season, blaming losses on extreme discounts from rivals.

Cramer said the electronics retailer needs a "big reset," and that analysts erred in thinking the company could compete with online shopping outlets. He said the holidays were an "Amazon quarter."

Best Buy hurt its bottom line by trying to compete with heavy discounts, Cramer said.

"This is just a sample of what happens when you get way too bullish ahead of the quarter," Cramer said. "Why did people start liking it versus Amazon? Because they cut prices dramatically, and they offered the lowest price. Well, it turns out when you offer the lowest price, you don't make as much money."

In a conference call with Wall Street analysts, Best Buy CEO Hubert Joly tried to allay concerns about the weaker-than-expected holiday season.

"We've hit a speed bump," Joly said. "And we don't want to minimize it because frankly we care deeply about our month-to-month performance. But our sense is that it doesn't change the overall story. It doesn't change the long-term perspective."

A bad holiday season makes for a hard recovery in the retail sector, especially for big-ticket electronic items, Cramer said. The months between holiday seasons are "humdrum" for retailers, he said.

"Without a doubt the momentum that Best Buy had is over, and I don't know whether you can recover," Cramer said. "You've got a four-month window ... I'm not going to Valentine's Day and buying anyone a 60-inch [TV] screen."

Disclosure: Cramer's charitable trust does not own shares of either Amazon or Best Buy.
