Vistra (VST) has been front and center lately, due to its ties to the current surge in electricity demand linked to artificial intelligence and booming data center construction. Market watchers are buzzing about what this means for the company. Recent analyst upgrades, strong earnings, and favorable results from power capacity auctions have all added fuel to the conversation, making investors naturally wonder whether Vistra is setting up for a new era of growth or if this momentum is already priced into the share price.

The excitement around Vistra does not come out of nowhere. Over the past year, the stock has climbed an eye-catching 153%, with much of that enthusiasm building in recent months. Backed by annual revenue and profit gains, and major investments in its diversified energy portfolio, including nuclear, Vistra has managed to ride structural changes in the power sector. While there have been other gains and dips along the way, this year’s run-up highlights just how much the market now pays attention to the company's positioning in a changing industry.

After such a strong rally, investors have to ask themselves: does Vistra still offer compelling value here, or is the market already pricing in all of its future growth?
