Markets Today — May 15, 2026: The Summit Ended, and So Did the Rally
Wall Street hit record highs on Thursday. The Dow reclaimed 50,000. The S&P 500 crossed 7,500 for the first time ever. The Nasdaq added nearly 1%. It felt like a moment.
By Friday morning, it was already yesterday’s news.
Stocks fell broadly on May 15 as investors took profits in technology, processed a two-day U.S.-China summit that delivered more photo opportunities than firm agreements, and watched oil prices creep higher again. The tone going into the weekend is cautious — which is probably the right disposition after a rally that has pushed valuations deep into historically expensive territory.
Here is a complete breakdown of what happened, what drove it, and what it means for Canadian investors heading into next week.
U.S. Markets — The Numbers Behind Friday’s Pullback
The retreat on Friday was broad but not panicked.
The S&P 500 fell approximately 1.1%, giving back a meaningful portion of Thursday’s gains. The Dow Jones Industrial Average dropped around 407 points, or 0.8%. The Nasdaq Composite, which had led the charge higher all week, shed about 1.6% as technology stocks bore the brunt of the profit-taking.
The one bright spot in an otherwise red session was the Russell 2000, the small-cap index, which managed a gain of roughly 0.7%. Small caps tend to move differently from mega-cap tech, and Friday’s mild divergence suggested that some investors were rotating out of high-flying technology names and into companies with more grounded valuations.
What Triggered the Selloff
Two catalysts stood out.
The first was the obvious one: after a powerful multi-week run in technology and AI-related stocks, some degree of profit-taking was overdue. Chip stocks had surged aggressively over the prior month, creating conditions that many analysts described as unsustainable in the short term.
The second catalyst was Treasury yields. The 10-year U.S. government bond yield remains near 4.5%, continuing to pressure growth stocks with stretched valuations. With the Federal Reserve still showing no urgency to cut rates, investors are becoming more selective with high-multiple technology names.
Chip Stocks Gave Up Ground
Nvidia fell roughly 3% on Friday, Intel retreated 6%, AMD dropped around 3%, and Micron Technology shed approximately 5%.
Cerebras Systems, which debuted publicly on Thursday with a massive opening-day surge, also slipped around 5% during Friday’s session.
The move does not invalidate the AI thesis. Demand for AI infrastructure remains real. But markets are beginning to distinguish between strong businesses and overheated pricing.
The Trump-Xi Summit — What Actually Happened
The two-day summit between U.S. President Donald Trump and Chinese President Xi Jinping in Beijing wrapped up Friday with a constructive tone but limited structural progress.
What Was Agreed
Trump announced that China agreed to purchase American oil and roughly 200 Boeing aircraft.
Both leaders also emphasized the importance of keeping the Strait of Hormuz open amid ongoing tensions tied to Iran and global energy supply concerns.
Xi described the meetings as “historic” and reiterated support for stable economic and trade relations between both countries.
What Was Not Resolved
No comprehensive trade framework was announced.
Tariffs were reportedly not discussed directly, despite both countries still maintaining elevated tariff rates on each other’s goods.
There were also no major developments regarding Taiwan, semiconductor export restrictions, or long-term enforcement mechanisms.
For investors, the summit stabilized geopolitical tone but failed to create the kind of breakthrough markets had partially priced in.
Canada’s Market and the TSX This Week
Canadian markets remained supported by elevated oil prices throughout the week.
WTI crude traded above $102 per barrel while Brent crude climbed above $107. Elevated energy prices continue to benefit major TSX energy producers through stronger cash flow, dividends, and margin expansion.
Manulife Financial (TSX: MFC) — The Earnings Miss
Manulife reported Q1 2026 earnings below analyst expectations.
Core earnings came in at $1.06 per share versus expectations near $1.09. Softer Canadian and U.S. operations weighed on results, although the company’s Asia division continued to perform well.
The company still raised its quarterly dividend, maintaining its long-term dividend growth reputation.
For long-term investors, the miss is notable but not thesis-breaking. Asia remains the primary growth engine behind the stock.
The Week in Canadian Context
Energy and materials benefited from higher commodity prices.
Financials produced mixed earnings results, while the broader macro backdrop — higher rates, sticky inflation, and delayed rate cuts — continues to favour disciplined, income-focused investing over speculative momentum chasing.
Cisco Systems — The Earnings Standout of the Week
Cisco delivered one of the strongest earnings surprises of the week.
The company beat both revenue and earnings expectations while raising forward guidance significantly above analyst estimates.
Shares surged more than 13% after management highlighted accelerating AI infrastructure demand.
Cisco also revealed that AI-related orders are becoming a larger structural contributor to business growth, reinforcing the idea that the AI spending cycle now extends beyond semiconductor manufacturers into networking and infrastructure providers.
That matters for Canadian investors because it broadens the AI investment narrative across multiple sectors.
Bill Ackman Buys Microsoft — What It Signals
Bill Ackman disclosed a new Microsoft position this week after the stock’s earlier pullback.
Ackman described Microsoft as one of the world’s dominant technology franchises and suggested that the valuation offered a rare opportunity relative to the broader market.
The takeaway is less about blindly following hedge funds and more about understanding where sophisticated capital sees durable value amid a market increasingly driven by AI speculation.
Selective quality still matters.
The Contrarian View — Is This Market Running Out of Road?
Three observations matter heading into next week.
First, markets hit all-time highs Thursday and reversed immediately Friday.
Second, leadership inside the S&P 500 remains narrow, heavily concentrated in AI-related mega-cap technology names.
Third, valuation concerns are growing louder among veteran investors and strategists.
None of this guarantees an imminent crash. But it does reduce margin of safety for aggressively chasing momentum at current levels.
Discipline matters more here than excitement.
Key Takeaways for the Week
This week delivered record highs, geopolitical headlines, strong earnings surprises, and renewed valuation concerns all at once.
The AI infrastructure story remains intact.
Energy markets remain supportive for Canadian producers.
But higher rates, expensive valuations, and limited policy breakthroughs continue to create friction beneath the surface.
For Canadian investors, diversification and selectivity remain the highest-leverage strategy.

Conclusion
The week of May 11–15, 2026, tested investor discipline.
Markets reached historic highs before immediately pulling back. The Trump-Xi summit reduced geopolitical tension without producing structural breakthroughs. Corporate earnings reinforced the AI infrastructure trend while also exposing weakness in more rate-sensitive sectors.
The investors best positioned going forward are likely the ones who avoided chasing euphoric momentum and stayed anchored to long-term fundamentals.
Next week’s Nvidia earnings report will likely become the market’s next major catalyst.
