It has been tough for investors to jump on the semiconductor bandwagon. Names such as Micron (MU), SanDisk (SNDK) and Lam Research (LRCX) have been on fire in 2026. Several of the names in the VanEck Semiconductor ETF (SMH) reached new highs this past quarter and extended out. It has been an impressive run but no question these stocks have risen high enough for investors to start thinking about taking profits.
Remember, nobody rings a bell at the top, and there are a million reasons to sell, but only one reason to buy. “In the event of a crash landing, hit the sell button as quickly as possible.”
While Marvell Technology (MRVL) has had a marvelous year so far a little sideways consolidation might be needed here. Earnings won’t be out again until early August and I suspect when other names report before Marvell that could help drive the stock higher.

The technical picture is showing far less bullishness than in the spring. MACD is firmly on a sell signal while money flow just went negative last month, the first time since March.
Parabolic SAR (stop and reverse) is on a sell signal while relative strength is poor, making lower highs and lower lows. The chart is teal so that means cautiously bullish.
Marvell’s strength in its core business is why we are in the name, and after a 100% runup from April to June we can accept a little giveback. Just not too much.
We like Marvell in TheStreet Pro Portfolio and rate it a Two, or “stockpile on pullbacks.”
