KLA Corporation stock gains 3.94 percent on Nasdaq

KLA Corporation stock (ISIN US4824801009) closed at USD 183.97 on Nasdaq on September 21, 2026, up 3.94 percent from the previous close. The move gives the semiconductor equipment maker a clear market signal as chip stocks recover from their September weakness.

Stock rises with chip equipment

According to Ad-hoc-News on September 22, 2026, the Nasdaq close of USD 183.97 represented a 3.94 percent daily gain. The dated price and percentage are the key market figures for the latest completed session.

Sector context added to the move. According to Investing.com on September 22, 2026, KLA gained 3 percent in the reported two-session rotation into chip manufacturing tool companies, while the SOXX semiconductor index rose less than 1 percent. That comparison indicates stronger buying interest in equipment names than in the broader chip basket during the cited move.

Valuation remains the counterweight

The latest valuation figures create a measurable counter-factor. GuruFocus reported on September 21, 2026, that its GF Value estimate was USD 112.08 against a share price of USD 183.97, a difference of 64.1 percent. A separate GuruFocus analysis on September 21, 2026, placed earnings-based intrinsic value at USD 117.38 and free-cash-flow-based intrinsic value at USD 89.19.

Those estimates are valuation models, not company guidance or analyst consensus. For the stock, the important quantified contrast is the 3.94 percent Nasdaq gain against model values of USD 112.08, USD 117.38 and USD 89.19.
