Nothing lasts forever, and we all know markets can change. But now that the chip rally has stalled, investors have to choose whether to walk away from the spectacular gains semiconductor stocks have posted this past year, or ride out the turbulence.

Many of the chip trade's biggest winners back up their gains with earnings, others are riding a wave that may leave them stranded after it crests.

Five of these stocks look especially ripe for profit-taking, based on fundamentals, valuations, and technical signals hinting at fading bullish momentum. 

Here are the five chip stocks to sell right now.

Microchip Technology Inc.

Microchip Technology (NASDAQ:MCHP) has gained more than 40% year-to-date (YTD), which may seem like a lighter gain than some of its semiconductor peers. But the reason Microchip is flagged for profit-taking following this gain is valuation and its inability to support its dividend.

The stock's Price-to-earnings (P/E) ratio is currently above 400, signifying how deep an earnings recovery the company needs to make from the past cycle. At 30 times forward earnings and 10 times sales, the stock still needs to show significant earnings growth to justify its valuation. Insiders sold more than $50 million worth of shares in Q2 2026, and the dividend payout ratio is an unsustainable 800% after 23 straight years of payout increases.

Valuation was the underlying concern, and fiscal Q4 2026 earnings were the catalyst that triggered the downside. Despite 35% year-over-year (YoY) revenue growth, data center guidance projections were flat, which isn't what a company with a forward P/E near 30 wants to see. With the share price now nearing the 50-day moving average amidst bleeding momentum from the Relative Strength Index (RSI) and Moving Average Convergence Divergence (MACD) indicator, it looks like profit-taking is the wise move for MCHP shareholders.

ASE Technology Holding Co. Ltd.

Taiwan-based ASE Technology Holding Co. (NASDAQ:ASX) is one of the world's largest testing and advanced packaging semiconductor companies and has been a major beneficiary of the AI bottleneck problem. The stock has more than doubled YTD, and is up more than 240% over the last 12 months.

The gains have been warranted; ASX has grown quarterly revenue by at least 12% YoY in the last four periods, and management continues to paint an optimistic guidance picture. Margins compressed surprisingly in Q1 2026, which is an obvious red flag for a company that now trades at 55 times earnings and 3.7 times sales. Revenue will likely continue to accelerate, but the growth story is likely priced in, and investors are now demanding profits rather than sales.

ASX shares are only 10% off their all-time highs, which means investors can take profits here and still walk away with hefty gains. A bearish MACD crossover signals that momentum has swung toward sellers, and the RSI is on the verge of breaking below the bullish threshold of 50.

Trio-Tech International

Small-cap printed circuit board and LED designer Trio-Tech International (NYSE:TRT) has gotten caught up in the semiconductor rally despite its lack of fundamental growth. This appears to be a pure retail mania play, and there's plenty of evidence that profit-taking has already begun.

Trio-Tech has a market cap of approximately $105 million, making it a tiny, illiquid stock prone to drastic volatility swings. The company only made $58 million in revenue over the last 12 months, and its stock currently trades at more than 200 times earnings. The company also issued $10 million in stock in April, a clear dilutive move from a firm looking to raise capital following a momentum-induced run.

The MACD and RSI have been in a steady decline for weeks following the blow-off top in mid-May, but now the stock appears to be rolling over hard. Shares are below the 50-day moving average for the first time since the rally started in March, and exiting large positions can get tricky when liquidity is this low. TRT shares cannot sustain their current valuation, so a deeper selloff is more likely than a rebound.

Ichor Holdings Ltd.

Ichor Holdings (NASDAQ:ICHR) has been a hot stock this year thanks to its crucial water delivery systems for semiconductor equipment and data centers. A classic “picks and shovels” play on the AI infrastructure buildout, ICHR shares have enjoyed parabolic gains over the last 12 months (nearly 300%). And unlike many of its peers, the stock still sits relatively close to the all-time high it notched in May.

But the stock performance belies the fading momentum under the surface, and the lack of profits is beginning to come into focus. The company's net income over the last 12 months was nearly $53 million in the red, and its forward P/E of 49 is higher than that of industry peers like KLA, Applied Materials, and Lam Research.

The rally has gotten ahead of analyst price targets, and momentum is fading hard on the technical indicators. The RSI and MACD have been moving straight down since the end of April, and the stock recently took out the 50-day moving average. Shares popped by more than 6% on Tuesday, offering investors an ideal level to take profits. 

IREN Ltd.

IREN (NASDAQ:IREN) is in the confluence of two volatile asset classes: cryptocurrency and semiconductor stocks. The former Bitcoin miner has pivoted to AI infrastructure, using excess mining capacity for data center compute. The company also retains significant Bitcoin holdings, which provides a double whammy in the current market environment.

Despite massive commitments from Microsoft, Dell, and NVIDIA, valuation is once again spiking the punch bowl. The stock trades at 77 times earnings and 22 times sales, and it will need flawless execution (plus a Bitcoin rebound) to justify these numbers.

The stock is up more than 400% in the last 12 months, but momentum has been looking weak recently. IREN shares corrected sharply over the last 5 trading sessions, losing more than 10% as indicators like the RSI and MACD flipped from bullish to bearish. The 50-day moving average has been a strong support level for the last two months, but it now appears shaky as fundamental concerns collide with downward technical momentum.
