Key Takeaways: Nvidia's stock has soared in recent years, but historical patterns suggest the weeks before its Aug. 26 earnings could determine the AI chip leader's next move.

Nvidia faces a key test on Aug 26 as history shows 3 patterns
Nvidia Corp. shares have surged more than 1,000% from their 2022 lows, yet the stock has lost momentum in 2026, closing at $206.84 on Thursday as the Philadelphia Semiconductor Index dropped 4.3%. The Aug. 26 event — widely expected to be Nvidia's fiscal second-quarter earnings report — represents the next major test for a company that dominates the AI chip market with an estimated 80% share.
"Investors are trying to decide whether the recent pullback is a buying opportunity or the start of a deeper correction," said Bret Kenwell, an analyst at eToro. "Nvidia's results will set the tone not just for the company but for the entire semiconductor sector."
The broader chip sector has been volatile. The Philadelphia Semiconductor Index surged 87% in the second quarter, its best quarterly performance on record, before giving back some gains. The VanEck Semiconductor ETF, which allocates 20.8% of its $70.6 billion portfolio to Nvidia, has returned 102% over the past year but remains sensitive to shifts in AI infrastructure spending. Analysts have a consensus price target of roughly $749 on the SMH ETF, implying about 30% upside from current levels. The iShares PHLX Semiconductor ETF, with $45.9 billion in assets, holds Nvidia at 8.3% and has returned 127% over the past year, benefiting from larger allocations to Advanced Micro Devices Inc. and Intel Corp.
The stakes for Nvidia are unusually high. The company's data center business, which generated more than $30 billion in revenue last quarter, depends on sustained capital spending from hyperscalers including Microsoft Corp., Amazon.com Inc., Alphabet Inc., and Meta Platforms Inc. Any sign that those customers are tempering their AI infrastructure budgets could trigger a reset in earnings expectations. Nvidia trades at roughly 35 times forward earnings, below its peak near 45 times but well above the 18-times support level the sector has found over the past two years.
What History Shows
Historical patterns offer mixed signals. In the four quarters since Nvidia joined the Dow Jones Industrial Average, the stock has rallied an average of 8% in the three weeks before earnings, according to data compiled by Bespoke Investment Group. But it has also sold off an average of 3% in the week following the report, as investors lock in profits after the run-up.
The pattern reflects a broader tension in AI stocks. The Philadelphia Semiconductor Index's valuation has been volatile, peaking near 45 times forward earnings over the past decade while finding support around 18 times in the last two years. Earnings expectations for both this year and next have risen sharply, leaving less room for disappointment. The SOX index's forward P/E has swung between 18 and 45 times over the past decade, with the current level near 25 times — above the historical median but below the frothiest levels of the AI boom.
Risks and the Road Ahead
Semiconductor investors face several risks beyond Nvidia's specific results. Export controls targeting advanced chips to China could limit the company's addressable market. Tariffs and supply-chain disruptions remain a concern, as does rapid technological change that can alter market leadership. Advanced Micro Devices Inc. and Intel Corp. are both investing heavily in AI accelerators, though neither has meaningfully eroded Nvidia's market share. Intel shares fell 7.9% on Thursday to $92.32, while AMD dropped 3.3% to $521.95, reflecting broad sector weakness.
Nvidia shares, trading at roughly 35 times forward earnings, have priced in significant growth. If the Aug. 26 report confirms that demand remains strong and guidance exceeds expectations, the stock could resume its upward trajectory. If it reveals any cracks in the AI spending narrative, the sell-off could be sharp. For investors, the question is not whether Nvidia dominates AI chips today, but whether the market has already paid for that dominance.
