RBC Downgrades Tech Sector as Chip Momentum Slows
RBC Capital Markets downgraded the technology sector from overweight to market weight, citing decelerating earnings estimate revisions in the semiconductor industry. This follows a similar warning from Deutsche Bank last Friday. Analysts point to a potential down leg in tech stocks after a strong rally, with the iShares Semiconductor ETF (SOXX) down 19% from its high. Concerns about AI capex sustainability and market concentration are growing. The rotation could broaden market performance but also risks a wider sell-off.
This news reflects a shift in investor sentiment away from tech stocks, which could impact ad tech companies that rely on digital advertising spending. However, it is not directly about ad tech and is a general market analysis.

Citi Cuts Tech Weighting Over AI ROI Concerns
Citi strategist Scott Chronert downgraded the bank’s recommended tech sector weighting to market weight from overweight, saying semiconductor strength and idiosyncratic moves among the largest tech names make it “difficult to see how everyone in AI/Tech path wins.” The move comes as markets pulled back after a New York Times report that OpenAI may delay its IPO; chip stocks were hit (Nvidia ~1% decline, Micron ~4%, VanEck Semiconductor ETF SMH down ~3%). Chronert remains broadly bullish on equities, keeping an 8,100 year‑end S&P 500 target, but expects a rotation away from tech as positioning broadens.
Bank of America Analyst Sees SOX Could Drop 10%
Bank of America's chip analyst Vivek Arya warned that the PHLX semiconductor index (SOX) could decline as much as 10% in a client report, extending recent losses. Arya cited technical factors, rising rates, political pushback, data-center backlash, and financing concerns — plus heavy ownership of chips (13% overweight vs. the S&P 500) — as near-term headwinds. He noted SOX's forward PE has equalized with the S&P at about 20x while companies in the index are growing forward EPS at an annual rate near 70%, making valuation appear attractive on a forward-growth basis. Bank of America highlighted “enhanced buy opportunities” in several chip stocks including Nvidia, Marvell Technology, Micron, Lam Research, AMD, Intel, Analog Devices and ON Semiconductor. Arya also flagged downside risks for Nvidia around capital returns and uneven enterprise sales.
Global Tech Sell-Off Intensifies
Global equity markets experienced a sharp sell-off led by technology and semiconductor stocks on June 23, 2026. South Korea’s Kospi plunged about 10%, driven by drops exceeding 12% in SK Hynix and Samsung. European benchmarks fell, with the Stoxx 600 down roughly 1% and its Technology index off about 3%. U.S. Nasdaq 100 futures fell ~2.7% and semiconductor names and ETFs posted steep losses (SOXX down ~6.2%; Intel, Micron, AMD and Nvidia all lower). SpaceX shares extended earlier declines. Market commentators including Wedbush’s Dan Ives framed the sell-off as a potential buying opportunity, while Tom Hulick of Strategy Asset Managers said liquidity and earnings momentum reduce the risk of a market catastrophe. Micron’s upcoming earnings were cited as a near-term catalyst.
