Futures for the major indexes are showing a downward bias, particularly in the tech-heavy Nasdaq.<\/p>\n<p>The State Street SPDR <a href=\"https:\/\/stockmarketwatch.com\/indices\/sp500\/today\" data-internallinksmanager029f6b8e52c=\"3\" title=\"snp500 today\">S&amp;P 500<\/a> ETF Trust (<a href=\"\/stock\/SPY\">SPY<\/a>) and the Invesco QQQ Trust (<a href=\"\/stock\/QQQ\">QQQ<\/a>) are both seeing selling pressure in early trading. While the State Street SPDR <a href=\"https:\/\/stockmarketwatch.com\/indices\/dowjones\/today\" data-internallinksmanager029f6b8e52c=\"1\" title=\"Dow Jones Today\">Dow Jones<\/a> Industrial Average ETF Trust (<a href=\"\/stock\/DIA\">DIA<\/a>) remains relatively more resilient, the broader market sentiment is being weighed down by a retreat in semiconductor and &quot;Magnificent Seven&quot; names. Investors are closely watching the iShares Russell 2000 ETF (<a href=\"\/stock\/IWM\">IWM<\/a>) to see if small-cap stocks can decouple from the large-cap tech slide.<\/p>\n<h2>Tech Giants and Semiconductors Lead Premarket Declines<\/h2>\n<p>The primary story of the morning is the retreat in high-valuation technology stocks. <a href=\"https:\/\/stockmarketwatch.com\/stock\/NVDA\" data-internallinksmanager029f6b8e52c=\"15\" title=\"stock: NVDA\">Nvidia<\/a> Corp (<a href=\"\/stock\/NVDA\">NVDA<\/a>) is among the most active tickers, trading down 1.8% <a href=\"https:\/\/stockmarketwatch.com\/movers\/premarket\" data-internallinksmanager029f6b8e52c=\"7\" title=\"Premarket Movers\">premarket<\/a> at $216.91. This weakness is echoing across the semiconductor space, with <a href=\"https:\/\/stockmarketwatch.com\/stock\/MU\" data-internallinksmanager029f6b8e52c=\"20\" title=\"Stock: MU\">Micron<\/a> Technology, Inc. (<a href=\"\/stock\/MU\">MU<\/a>) falling 2.2% and <a href=\"https:\/\/stockmarketwatch.com\/stock\/SNDK\" data-internallinksmanager029f6b8e52c=\"19\" title=\"Stock: SNDK\">Sandisk<\/a> Corporation (<a href=\"\/stock\/SNDK\">SNDK<\/a>) dropping 2.9%.<\/p>\n<p><a href=\"https:\/\/stockmarketwatch.com\/stock\/MSFT\" data-internallinksmanager029f6b8e52c=\"18\" title=\"Stock: MSFT\">Microsoft<\/a> Corp (<a href=\"\/stock\/MSFT\">MSFT<\/a>) is also seeing a pullback of 1.4%, trading near the $500.20 level. These movements appear to be a combination of profit-taking after a strong summer and investor anxiety ahead of critical economic data points due later this week. In the broader tech ecosystem, Apple (<a href=\"\/stock\/AAPL\">AAPL<\/a>), Google (<a href=\"\/stock\/GOOGL\">GOOGL<\/a>), and Tesla (<a href=\"\/stock\/TSLA\">TSLA<\/a>) are also being monitored closely for signs of a broader rotation out of growth and into defensive sectors like the State Street Utilities Select Sector SPDR ETF (<a href=\"\/stock\/XLU\">XLU<\/a>).<\/p>\n<h2>Upcoming Economic Events and Earnings<\/h2>\n<p>The focus for today\u2019s session will shift to the ISM Manufacturing PMI report, scheduled for release shortly after the opening bell. This data is a critical barometer for the health of the U.S. economy and will likely influence the Federal Reserve&#39;s upcoming policy decisions regarding interest rates. Market participants are looking for signs of cooling inflation without a significant contraction in industrial activity.<\/p>\n<p>On the corporate earnings front, Medtronic plc (<a href=\"\/stock\/MDT\">MDT<\/a>) reported its Q1 2027 results before the open, posting an estimated EPS of $1.39 on revenue of $9.55 billion. However, the most anticipated reports will arrive after the closing bell. Palo Alto Networks, Inc. (<a href=\"\/stock\/PANW\">PANW<\/a>) is set to report its Q4 2026 results, with investors looking for guidance on cybersecurity spending. Similarly, Zscaler, Inc. (<a href=\"\/stock\/ZS\">ZS<\/a>) will report after the close, providing further insight into the cloud security landscape.<\/p>\n<h2>Notable Movers and Small-Cap Activity<\/h2>\n<p>In the speculative and small-cap space, several stocks are making massive moves on high volume. GoPro, Inc. (<a href=\"\/stock\/GPRO\">GPRO<\/a>) surged 72.9% in premarket trading, leading the gainers list. Other significant movers include bioAffinity Technologies, Inc. (<a href=\"\/stock\/BIAF\">BIAF<\/a>), which rose 44.8%, and AEye, Inc. (<a href=\"\/stock\/LIDR\">LIDR<\/a>), which climbed 42.7% on unusual volume.<\/p>\n<p>Conversely, Alumis Inc. (<a href=\"\/stock\/ALMS\">ALMS<\/a>) is the morning&#39;s biggest loser, shedding 54.4% of its value. As the market opens at 9:30 AM ET, traders will be looking to see if the early weakness in the VanEck Semiconductor ETF (<a href=\"\/stock\/SMH\">SMH<\/a>) persists or if buyers step in to defend key support levels on the S&amp;P 500.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Market Overview: September Kicks Off with Tech Volatility As Wall Street enters the first trading day of
