KLA Corporation stock rose 6.45% to $184.09 on Tuesday, driven by a strong intraday performance that included a 3.4% gap up at the open and a session high of $184.24. The move followed recent commentary from Jim Cramer, who highlighted the stock as a potential buy in small doses, and appears to reflect renewed investor interest in the semiconductor equipment maker. The stock traded at 1.5 million shares, a fraction of its 3-month daily average, suggesting a relatively quiet but directional session.

What Happened

KLA Corporation (KLAC) opened the session at $178.77, up 3.4% from the previous day's close of $172.94. The stock climbed steadily throughout the morning, reaching a high of $184.24 at 9:50 AM ET before consolidating near the session close at $184.08. The move followed a recent appearance on Mad Money, where Jim Cramer advised buying the stock in small doses after it had pulled back from its June peak above $300. The commentary appears to have influenced the session's tone, as the stock moved higher despite a lack of major corporate announcements or earnings reports.

What The Data Shows

KLA has a market cap of $225.1 billion and a P/E ratio of 47.3, with trailing twelve-month revenue up 11.7% and a net margin of 35.6%. The stock has traded between $83.22 and $307.37 over the past 52 weeks. On the options and retail front, no unusual options activity was reported, and no significant social media chatter was noted. Recent insider transactions show 16 sales totaling $64.5 million in the last 90 days, with no insider purchases. Meanwhile, several members of Congress have made small purchases of the stock in the same period.
