Hewlett Packard Enterprise stock had a week for the books

Hewlett Packard Enterprise's ( HPE ) investor day this week was a resounding success as far as Wall Street is concerned. That much is evident by the stats on the company's stock this week.

The server and networking equipment maker's stock was the biggest gainer in the S&P 500 ( ^GSPC ), per AlphaSpace data. It hit back-to-back record highs on Wednesday and Thursday, and shares were on track to eclipse those highs on Friday.

All in, the stock is pacing for a 10% gain this week, building on the shares' 189% year-to-date rise.

The stock climbed roughly 8% on Friday amid a positive reaction to the company's investor day on Wednesday, a litany of Wall Street analyst upgrades and price target increases, and broader gains in the tech sector.

Ahead of Wednesday's investor day, HPE announced it had secured a $1.2 billion order from Vultr, a privately held cloud infrastructure company, to deploy its Helios AI server racks , powered by AMD chips, at Vultr's US data centers.

The deal marks HPE's first order for the new AMD Helios system.

"We unveiled our switch on the floor and, as I think our general manager of our data center business, Praveen Jain, said, it was literally a work of art," Hewlett Packard Enterprise CFO Marie Myers told Yahoo Finance on Wednesday. "1,700 copper cables all packed into this massive switch, and we actually increased our revenue guide for '27 and '28. So we're really seeing the power of this portfolio coming together, and it's a super exciting day."

Then, later that day, HPE raised its fiscal year 2027 revenue growth outlook for the networking segment. The company now sees a growth rate in the high-teens to low-20s range.

HPE also projected Data Center Networking revenue to grow in the low- to mid-50% range annually through fiscal year 2029. Networking segment operating margins are forecast in the mid- to high-20% range.

HPE finds itself at the center of the AI boom , which is driving a surge in demand for servers and high-performance networking infrastructure.

"Demand is continuing to outpace supply. It's no doubt that we continue to be in a supply-constrained environment," Myers said. "So certainly the tailwinds that we see around AI aren't changing anytime soon."

Wall Street cheered the upbeat outlook and AMD Helios order, with analysts from Evercore ISI, Morgan Stanley, Citigroup, Truist, and UBS all raising their price targets on the stock.
