Key Highlights

  • Apple unveiled iPhone Duo on Sept. 9 from $1,999; pre-orders open Oct. 16 and availability begins Oct. 23 in 70-plus markets.
  • Morgan Stanley's Erik Woodring called early iPhone 18 Pro Demand "fine," with lead times of two to four weeks, but described the valuation as relatively rich.
  • Apple's June-quarter Revenue rose 16% to $109.4 billion, but its September-quarter growth guidance of 9% to 11% missed expectations.
  • Apple is the second-largest Nasdaq-100 constituent at about 11.44% of the index, with shares trading near $339.75 in the latest session.

Apple's first foldable matters for the stock because it gives the company a new, higher-priced product at a time when investors are already paying a premium for its earnings. On Sept. 9, Apple (NASDAQ:AAPL) introduced iPhone Duo, starting at $1,999 in the U.S., alongside the iPhone 18 Pro lineup. Pre-orders open Oct. 16 and the device goes on sale Oct. 23 in more than 70 countries and regions.

Early signals on the broader iPhone cycle look steady. On Sept. 21, Morgan Stanley (NYSE:MS) analyst Erik Woodring said early demand for the iPhone 18 Pro and Pro Max "seems fine," with delivery lead times of roughly two to four weeks depending on region. He also said Apple trades at a "relatively rich" valuation, which he put at about 33 times his fiscal 2027 Earnings estimate.

That leaves the Duo launch carrying real weight. Apple is the second-largest Nasdaq-100 constituent at about 11.44% of the index, with the shares at $339.75 in the latest session. How the foldable sells could influence both Apple's earnings estimates and the multiple investors are willing to pay for them.

What Apple Unveiled on Sept. 9

According to Apple's Sept. 9 press release, iPhone Duo pairs a 7.6-inch inner display with a 5.4-inch outer display that delivers 90% of the screen area of iPhone 18 Pro. Apple says the device, when opened, is the thinnest iPhone ever. It runs on the A20 Pro, the same chip used in the iPhone 18 Pro models, and uses a dual-battery design and a custom vapor chamber for thermal management.

The device comes in star white and night sky, in storage Options from 256GB to 2TB. Apple priced it from $1,999, or $83.29 per month over 24 months, and is also offering a leasing option through Klarna (NYSE:KLAR) starting at $57.99 per month. Customers in markets including the U.S., China, India, Japan, the UK and Germany can pre-order from 5 a.m. Pacific time on Oct. 16, with availability from Oct. 23. A further 28 countries and regions follow on Oct. 30.

Reading the Early iPhone 18 Pro Signals

Woodring's comments suggest a solid start rather than a breakout. He said lead times were broadly unchanged from last year, but cautioned that they reflect Supply as well as demand. Because Apple's Pro and Pro Max production is up about 18% year over year for the second half of the calendar year, by his estimate, flat lead times on greater supply could point to healthy demand.

China was the exception, with shorter lead times than last year. Woodring said some Chinese buyers may be waiting for the Duo before choosing a premium model, noting that China has historically been the strongest market for foldable phones. He said he is highly optimistic about the Duo and expects Apple could sell nearly every foldable it produces over the next 12 months. He also said investors should watch lead times about two weeks after launch, when they typically peak.

The June Quarter and a Softer Outlook

Apple's most recent results, released Jul. 30, showed strong momentum. Revenue for the fiscal third quarter ended Jun. 27 rose 16% to $109.4 billion, and Diluted Earnings per Share rose 29% to $2.02. Both figures included benefits from Tariff refunds, which Apple said added about 2 percentage points to its 50.1% gross Margin and $0.11 to earnings per share. Tim Cook called it "our strongest June quarter ever."

iPhone revenue rose 22% to $54.25 billion, ahead of estimates, while Services revenue of $30.74 billion came in slightly below the $31.22 billion consensus. Mac revenue reached $10.35 billion. The outlook was less upbeat: Apple guided to revenue growth of 9% to 11% for the September quarter, below the roughly 12% analysts expected, citing supply constraints, and the stock fell more than 6% in extended trading. CFO Kevan Parekh said the company expects iPhone sales to grow in the mid-teens year over year.

The Jul. 30 call was Cook's last as CEO before he hands Leadership to hardware chief John Ternus, adding a management transition to the product cycle.

Where the Duo Fits in a Crowded Foldable Market

Apple is entering a category that Android makers have developed for years, and it is doing so at the top of the price range. Its pitch rests on hardware and software integration, the size of its installed base, which the company says reached an all-time high in the June quarter, and a redesigned Siri that uses Google (NASDAQ:GOOGL) technology. For the stock, the question is less whether Apple can sell a foldable and more whether the device expands the average selling price and upgrade cycle enough to lift earnings estimates.

Valuation, Memory Costs and Other Risks

Valuation is the most direct risk. Woodring said Apple trades at about 33 times his fiscal 2027 estimate and 30 times fiscal 2028, close to a historical peak of roughly 34 to 35 times, and said further gains may require analysts to raise their earnings estimates.

Services is another watchpoint. Woodring expects Services growth to fall below 10% in the September quarter for the first time in several years, though he expects it to reaccelerate. Costs are a third pressure. Cook has described the global memory shortage as a "hundred-year flood," and Apple has already raised prices on Macs and iPads. Supply limits on components could also cap how many Duo units reach customers early on.

The Countdown to Duo's October Launch

The near-term calendar is clear. Duo pre-orders open Oct. 16, sales start Oct. 23 and the device reaches 28 more markets on Oct. 30. Lead times about two weeks after launch will be an early read on demand, especially in China.

Apple's fiscal fourth-quarter results are typically released in late October or early November, although a date has not yet been confirmed. That report should show whether the 9% to 11% growth guidance held and how the company frames holiday-quarter demand, memory costs and the progress of its leadership transition.
