Dell Technologies stock was climbing on Tuesday after a Mizuho analyst initiated coverage of the shares with an Outperform rating and said the maker of PCs and other hardware has some unique advantages.

In a major show of confidence, Dell (NYSE: DELL) is anticipated to see its stock benefit after its inclusion in the S&P 500 index.

Everybody knows that Super Micro Computer Inc. is top dog in the artificial-intelligence server market with a “dominant share,” according to Mizuho Securities — but that doesn’t mean investors should buy the stock.
