KLA Stock Extends An 8-Day Losing Streak To A 14% Loss

The stock closed at $178.81 on Wednesday, October 14, 40.7% below its 52-week high of $301.37 and 75.3% above its low of $102.02.

The Streak Next To The S&P 500

Returns for KLAC and the S&P 500 over the streak and the periods around it, all ending Wednesday, October 14 and including dividends:

How The Streak Compares With The Market

The market explains little of this: the S&P 500 gained 0.0% over the same 8 sessions, including dividends, against KLA's -13.6%. 1 other S&P 500 stock is currently on losing streaks of 8 days or longer. Over the past three months the stock is down 18.4%, a window that includes the streak; over the other 55 sessions of that window it was down 5.6%.

Is The Business As Weak As The Stock?

On the fundamentals, revenue grew 11.7% over the last twelve months, against a median of 17.9% for S&P 500 Information Technology stocks; its operating margin is 41.7%, versus a median of 21.6%; and the stock trades at 48.4 times trailing earnings against a median of 35.7. The read is mixed: margins above the median on one side, revenue growth below the median on the other.

If the drop has you weighing an entry, resist buying on price alone. Our Buy the Dip screen ranks the marked-down names where growth and cash generation still hold up.

For anyone who would rather back the theme than one company, a semiconductor ETF like SMH holds the whole group, not just this stock. It is still a concentrated bet on one theme, which is the gap the portfolio below is built to close.

A Slide Like This Is Why Diversification Exists

Watching one stock fall day after day is the clearest lesson the market teaches about single-name risk. Whether this particular decline is an opportunity or a warning, the deeper point is the same: no one name should be able to do this to your portfolio.

The Trefis High Quality (HQ) Portfolio is built on that principle: roughly 30 businesses selected for consistent cash generation, strong margins, and resilient balance sheets, sized and rebalanced with rules. It has a track record of outpacing a benchmark that combines the S&P 500, the S&P MidCap 400, and the Russell 2000. Study the slide; spread the risk.
