Analyst price targets and ratings are FMP consensus figures as of Oct 22, 2026; other aggregators may differ. High and low targets show the range of estimates, not forecasts.
MTSI fell 14.65% to $233.04 as part of a broader semiconductor sector sell-off hitting analog and power chip stocks including Monolithic Power Systems, AMD, and Semtech, driven by profit-taking and shifting sentiment on high-valuation AI infrastructure plays (web search, Oct 22, 2026). Volume of 900,944 shares at 0.84x expected for this time of day suggests orderly decline rather than panic.
MTSI fell 10.15% to $261.75 on October 15, 2026, driven by a broad semiconductor sector selloff rather than company-specific news. According to reporting cited by ca.investing.com and marketwatch.com, the decline reflects macro pressures including a weaker-than-expected U.S. jobs report, volatile energy prices, rising Treasury yields, and sector-wide reassessment of frontier AI infrastructure spending pacing — with peers like Lam Research and Marvell experiencing synchronized pullbacks. Volume of 962,791 shares (1.24x intraday average) is normal for the time of day.
MTSI fell 6.01% to $290.18, driven by sector-wide semiconductor profit-taking and AI capex sustainability concerns affecting high-beta optical chip suppliers (web catalyst). The broader semiconductor complex, including peers Micron (MU) and NVIDIA (NVDA), is retreating. Volume was 587,903 shares by 2:40 PM—60% of the time-adjusted daily average, indicating below-average participation.
MACOM (MTSI) fell 6.08% to $309.99, driven by a combination of sector-wide AI chip reassessment—major industry players issued cautious AI revenue guidance, stoking concerns about unsustainable hyperscale infrastructure spending—and recent insider selling by SVP Ambra Roth (Form 4 filing per Investing.com). The decline also reflects profit-taking pressure on a stock that had surged 170% over the trailing year and 93% year-to-date, with a P/E ratio near 99.35 making it vulnerable to valuation resets. Volume at 404,716 shares is 0.84x expected for this time of day.
MTSI rallied 6.33% to $349.09 following a BMO Capital upgrade to Outperform and investor enthusiasm over the company's newly launched 3.2-terabit optical chipset for AI data centers, according to web sources cited by Yahoo Finance. The stock also benefited from MACOM's participation in European Microwave Week (Oct. 6–8), where it is showcasing RF and microwave technology. Volume of 599,170 shares is running 0.90x the time-adjusted historical average.
MACOM Technology Solutions (MTSI) rose 7.41% to $323.97 following a BMO Capital analyst upgrade to Outperform and momentum around its 3.2-terabit optical chipset for AI data center infrastructure showcased at European Microwave Week.
