What Will Decide Apple Stock Over The Next Six Months?
If you own Apple (AAPL) after a 32% gain in a year, the worry is what could reverse it. In July 2026, management said memory would cost Apple even more in the September 2026 quarter. Higher memory costs mean less profit per device, and Apple still cannot build enough phones and Macs. The table below lists what could move Apple stock over the next six months and what matters most.
| What to watch | When | Which way it cuts |
|---|---|---|
| Supply limits on iPhone, Mac, and iPad | the September 2026 quarter (fiscal Q4 2026), results not yet reported | Either way |
| Demand for the new iPhone 18 Pro and iPhone Duo | the September 2026 quarter (fiscal Q4 2026), results not yet reported | In its favor |
| Memory prices are still rising after September, pressing on gross margin. | beyond the September 2026 quarter (fiscal Q4 2026); no end date stated | Against the stock |
| Apple’s next report | October 29, 2026 | Either way |
| Supreme Court appeal of the U.S. ruling on App Store link-out payments | no date stated | Either way |

Memory Costs Matter Most For Apple Stock
Rising memory costs matter most. They come out of Apple’s gross margin, the share of sales left after production costs. Management also said in July 2026 that it saw memory prices rising beyond the September 2026 quarter.
Gross margin was guided to 47% to 48% for the September 2026 quarter, whose results are still pending. Each point of gross margin is worth about $4.7 billion a year at Apple’s size. Apple has some relief from parts it bought earlier. Management expects that relief to shrink after September.
Watch the gross margin guide in Apple’s next report, which our earnings calendar lists for October 29, 2026, after the close. A guide below 47% would put the margin under the September 2026 quarter’s range.
Apple’s Supply Limits On iPhone, Mac And iPad
Apple cannot build as many iPhones, Macs, and iPads as it could sell. On the July 30, 2026 call, management said these limits would grow sharply in the September 2026 quarter. Management said the cause was strong demand, not supplier problems. iPhone and Mac sold far better than Apple had forecast.
Revenue growth was guided to 9% to 11% for the September 2026 quarter, down from 16% in the June 2026 quarter. Management said supply limits and currency moves explain nearly all of that slowdown. Management gave no guidance beyond the September quarter, so Apple has not said when the limits will ease.
At Apple’s next report on October 29, 2026, watch for word that the limits have eased.
Demand For Apple’s New iPhones
Demand for the new iPhones is the main chance of good news. Apple unveiled the iPhone 18 Pro and the iPhone Duo, its first foldable phone, on September 9, 2026.
Management guided iPhone revenue to grow in the mid-teens in the September 2026 quarter.
The early evidence is mixed. In India, some customers queued overnight for the iPhone 18 Pro, CNBC reported in September 2026. The iPhone Duo starts at $1,999 in the U.S. Some observers at its launch questioned who it is for, Reuters reported.
Watch iPhone revenue growth in the October 29, 2026 report. Read it alongside any word on supply, since the supply limits also cover iPhones.
Can You Hold Apple Stock Through These Dates?
The answer depends on how deep a fall you can sit through. The stock fell 8.7% over the two days around the July 30, 2026 call. Apple stock’s worst fall in the past year was deeper, at 13.8%. That fall started in early December 2025 and ended in late March 2026. At the low, $10,000 put into the stock at the start was worth about $8,620.
If you would sell in a repeat of that fall, your position is too large for these dates. Size it so that loss is money you can leave alone for months. Through these dates, watch whether Apple guides gross margin at 47% or above. Also watch whether Apple says the supply limits have eased.
Beyond AAPL: A Systematic Way To Grow Your Money
Before you decide on AAPL, consider a better choice. Since its inception, the Trefis High Quality (HQ) Portfolio has returned 105%, beating the benchmark that combines the three major indices – the S&P 500, S&P Mid-cap, and Russell 2000. And it did so without taking concentrated risk that comes with do-it-yourself stock picking.
