7 Red Days In A Row: Applied Materials Stock Is Down 18%

The stock closed at $446.63 on Wednesday, October 14, 38.2% below its 52-week high of $722.23 and 105.8% above its low of $216.99.

The Streak Next To The S&P 500

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

Is This Move About Applied Materials Or The Market?

Over the same 7 trading days, the S&P 500 returned -0.7% including dividends, so the slide is mostly Applied Materials' own story rather than the market's. 3 other S&P 500 stocks are currently on losing streaks of 7 days or longer. Over the past three months the stock is down 20.3%, a window that includes the streak; over the other 56 sessions of that window it was down 3.2%.

Do The Fundamentals Justify The Selling?

On the fundamentals, revenue grew 7.8% over the last twelve months, against a median of 17.9% for S&P 500 Information Technology stocks; its operating margin is 31.1%, versus a median of 21.6%; and the stock trades at 38.3 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.

A slide like this raises an obvious follow-up: which marked-down stocks are actually worth buying? Our Buy the Dip screen runs that test every day, flagging beaten-down names whose fundamentals 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.
