IT Research Stocks Surge 1.3 Trillion Won in a Day: What Happened?

Gartner Inc.’s shares surged 8.17% on the New York Stock Exchange on the 26th, closing at $136.98 per share—equivalent to roughly 210,000 KRW. Its market capitalization ballooned to about $9.2 billion (around 14 trillion KRW), with roughly $800 million (about 1.3 trillion KRW) added in a single day, and trading volume exceeded one million shares.

In its first-quarter earnings release, the company guided for a compound annual growth rate (CAGR) of at least 12% in adjusted EPS and set a 2026 adjusted EPS target of no less than $13.25. It also bolstered its shareholder-return program by authorizing an additional $600 million for share repurchases. Previously, in February, the stock plunged more than 20% after annual revenue and profit forecasts fell short of Wall Street’s expectations, fueling concerns about weakening demand in its consulting segment. This latest rally is being interpreted as a re-rating of what had been viewed as a conservative outlook for 2026.
