Micron, Marvell and Arm Stock Charts Flash The Same Warning — One Still Looks Cheap

The chip rally that carried U.S. markets to record highs this year has left three of its biggest winners hanging further above trend than anything else in the sector.

Only one of them still looks cheap.

Micron Technology, Inc. (NASDAQ:MU), Marvell Technology, Inc. (NASDAQ:MRVL) and Arm Holdings plc (NASDAQ:ARM) are now the most stretched stocks relative to their 200-day moving averages across the entire chip complex tracked by the iShares Semiconductor ETF (NASDAQ:SOXX). Intel Corporation (NASDAQ:INTC) sits just behind them.

Marvell trades roughly 250% above its 200-day line. Micron runs about 160% above. Arm sits near 130% and Intel around 113%.

SOXX itself trades about 65% above its own 200-day average, down from a peak near 85% in early June.

Why The 200-Day Gap Matters

The distance between a stock’s price and its 200-day moving average is one of the simplest ways to measure how far a rally has outrun its longer-term trend.

A wide gap confirms momentum. It also marks how much air sits beneath the price.

The gauge is not a timing tool. It measures a stock against its own trend and says little about whether a pullback is near.

History backs that up. Stocks that have already doubled their 200-day average have, in many cases, kept climbing for months before any reversal arrived.

Momentum Has Outlasted The Warning Before

Micron is the cleanest case study.

In the current cycle the stock first stretched more than 100% above its 200-day average on Nov. 10, 2025. It has soared more than 300% since, holding that elevated gap the entire way.

When it cleared the same threshold again in early May, it kept climbing rather than rolling over.

Only One Name Carries A Cheap Multiple

Where the four split is on price.

Micron trades near 9.8 times next-twelve-month earnings.

Marvell sits around 63.7 times forward earnings, Intel near 104 times and Arm above 159 times.

That divide reframes the warning. All four are technically overextended. Three are stretched on valuation at the same time.

Micron is the lone name where an aggressive run still rests on a low multiple, which leaves Marvell, Arm and Intel carrying the heavier load if momentum fades.

The charts agree on the risk. The fundamentals do not agree on who is most exposed.
