A sellout amid a selloff

Apple (NASDAQ:AAPL) edged higher on Friday, bucking a broad retreat in technology shares, after preorders for its $1,999 foldable iPhone Duo sold out within minutes, according to market reports. The stock climbed briskly in premarket trading before settling into a smaller gain once the regular session got under way and selling in technology intensified. Midday data showed shares at $343.46, and reports indicated the stock finished modestly higher.

Some analysts pointed to supply constraints as a factor in how quickly the device sold out, according to the same reports. That caveat matters: a fast sellout can reflect strong demand, limited initial supply, or both, and the reports did not settle which played the bigger role.

A rare winner on the Dow

Apple's gain stood out on the Dow Jones Industrial Average, which slipped 175.28 points to 52,002.41. Most of the index's technology members moved lower. Microsoft (NASDAQ:MSFT) and Amazon (NASDAQ:AMZN) slipped with the sector, Salesforce (NYSE:CRM) fell in a software rout, and reports on Nvidia (NASDAQ:NVDA) were mixed.

The wider market was weaker. The S&P 500 fell 84.62 points to 7,659.44 and the Nasdaq Composite tumbled 572.99 points to 26,140.03. According to market data, all but seven of the 75 technology stocks in the S&P 500 closed lower, putting Apple among a small group of tech names that ended in positive territory.

Why tech struggled

The day's selling centered on artificial intelligence and how it is financed. Market commentary described a shift in investor focus from what AI can do to how the infrastructure behind it will be paid for, with debt-funded names hit hardest. Chipmakers extended a long losing streak, and a 45-stock software basket lost roughly $130 billion in value, reports said.

One market commentator framed the shift this way: "The AI group is now splitting between companies that can fund the buildout themselves and those that have to borrow." Apple, which designs iPhones, Mac computers, wearables and services, had consumer hardware news on Friday that gave investors a different story to focus on.

Money also rotated toward energy, utilities, consumer staples and financials. Energy led the S&P 500 sectors as Brent crude rose to $109.86 a barrel on attacks on tankers in the Strait of Hormuz, according to market data.

Rates and the Fed in the background

Treasury yields eased over the week, with the 10-year yield finishing near 5.1, according to market data. Federal Reserve Chair Kevin Warsh, speaking at an IMF gathering in Bangkok, declined to preview the central bank's October decision, saying, "I don't prejudge meetings." The Fed raised rates by a quarter point in September, its first hike in three years.

iPhone Duo Supply Updates and Tech Earnings

The broader tech tape will be tested by a heavy week of earnings: Netflix (NASDAQ:NFLX) reports October 20, and Meta Platforms (NASDAQ:META), Tesla (NASDAQ:TSLA), Lam Research (NASDAQ:LRCX) and Texas Instruments (NASDAQ:TXN) report October 21. The Federal Reserve's next rate decision lands October 28, and the first estimate of third-quarter GDP and the PCE inflation report follow on October 29. Closer to home, investors will look for any update from Apple on iPhone Duo shipping times and supply, which could shape how the sellout is interpreted.
