A 5-Day Winning Streak Has Applied Materials Stock Up 14%

A five-day run has lifted the stock, but a look at the underlying business and recent performance shows a more complicated picture.

Applied Materials (AMAT) stock has now moved higher for 5 consecutive trading days, delivering a cumulative gain of 14%. That streak has added about $47 billion to the company's market value, which now stands at about $377 billion.

The recent gains come after a period of weaker performance; the stock has returned -2.0% over the trailing one month and -19.4% over the trailing three months. Applied Materials stock trades at about $474.38 a share as of 9/23/2026.

The Streak Next To The S&P 500

Here is how AMAT stock stacks up against the S&P 500 over the streak and the periods around it:

How does the business measure up to the price?

The company's fundamentals present a mixed view when set against medians for S&P 500 Information Technology stocks. Its operating margin of 31.1% is above the 21.6% median. However, its revenue growth over the last twelve months was 7.8%, which is below the median of 17.9%. The stock trades at a price-to-earnings multiple of 40.6, versus a median of 36.7.

The sources do not show why the move happened. The run has been the stock's own story, as the S&P 500 returned +2.0% over the same 5 trading days. The streak itself is not unique; 17 other S&P 500 stocks are currently on winning streaks of 5 days or more.

A streak is a signal, not an instruction.

A run of consecutive gains or losses is information. It tells you that a stock has momentum and has captured the market's attention. It is not, by itself, a reason to act. The disciplined response is to check the business against the new price. The numbers here provide a starting point for that work, weighing the stock's recent performance against its fundamental metrics.

A climb like this is worth respecting and worth testing: the momentum that lasts is usually the kind management itself is underwriting. Our Guidance Momentum screen tracks the stocks whose companies just raised their own forward numbers.

Those drawn to the strength but not the single-name risk have another route: a semiconductor ETF like SOXX holds the whole group, not the single stock. It is still a concentrated bet on that one theme, though, which is exactly the gap the portfolio below closes.

One Hot Stock Is A Story. Thirty Sound Ones Are A Strategy

A streak like this earns a place on your watchlist, and it also earns a question: how much of your outcome do you want depending on one company keeping this up?
