Wall Street just put together its longest weekly winning streak in nearly two and a half years. The S&P 500 closed Friday, May 22 at 7,473.47, up 0.37% on the day, capping an eighth consecutive weekly gain — the longest such run since December 2023, according to market reports. Small caps led the tape, quantum names ripped, and the AI capex thesis kept doing the heavy lifting.
The tape: small caps lead, indices grind to highs
All four major U.S. equity benchmarks finished the week in the green, with the Russell 2000 the clear leader on Friday. Per Yahoo Finance, the S&P 500 is now up 9.17% year-to-date and roughly 28% over the past five years.
| Index | Friday Close | Daily Move | YTD |
|---|---|---|---|
| S&P 500 | 7,473.47 | +0.37% | +9.17% |
| Dow Jones Industrial | 50,579.70 | +0.58% | — |
| Nasdaq Composite | 26,343.97 | +0.19% | — |
| Russell 2000 | 2,869.23 | +0.91% | — |
That Russell-leading-tech print is the kind of breadth signal bulls have been waiting on. For most of the cycle, gains have concentrated in the megacap AI cohort. Friday looked different: smaller, more cyclical names did the work while Nvidia — the cycle’s bellwether — quietly slipped 1.90% on heavy 147.7M-share volume, according to Yahoo Finance’s most-actives screen.
What drove the move
Three threads stitched the week together:
- AI capex re-acceleration. Nvidia’s Q1 FY27 print earlier in the cycle — a record $81.6B in revenue with a $91B Q2 guide — gave bulls cover to keep paying up for the hyperscaler/accelerator chain even after the stock itself sold the news.
- Sell-side green light. UBS lifted its S&P 500 price target, citing “resilient growth and AI tailwinds,” per Investing.com. When the strategist consensus chases the tape higher, it tends to lower the bar for incremental flows.
- Geopolitical de-risking. Progress in U.S.–Iran talks took some of the Middle East risk premium out of crude and risk assets, also per Investing.com.
Friday’s biggest movers
Speculative pockets dominated Friday’s most-active list. Quantum names — a group that has run on the back of D-Wave’s $100M CHIPS Act letter — ripped again. Ford was the headline cyclical winner.
| Ticker | Company | Close | Daily % | Volume |
|---|---|---|---|---|
| RGTI | Rigetti Computing | $26.42 | +19.87% | 185.5M |
| QBTS | D-Wave Quantum | $29.40 | +14.22% | 133.1M |
| F | Ford Motor | $14.93 | +9.22% | 96.7M |
| NOK | Nokia | $15.47 | +9.10% | 122.2M |
| NVDA | NVIDIA | $215.33 | -1.90% | 147.7M |
Eight straight weeks — in chart form
The eight-week run is the standout: only one streak of comparable length has shown up in the last two-plus years — the late-2023 rip that ended the post-October sell-off. The chart below visualizes the cadence of weekly index closes during the streak.
The risk: this is a stretched tape
Two cross-currents kept the bid intact but also raise the bar from here:
- Sentiment is hot. Eight-up weeks plus a sell-side target hike plus speculative pockets (quantum) trading like 2021 is the textbook profile of a market that is pricing optimistic outcomes. The VIX regime — tracked here as a backdrop — tends to compress through streaks like this, which historically lowers the cushion against single-stock or macro surprises.
- Rate-cut math has been giving back. The 2-year Treasury tested 4.10% as the market erased 2026 Fed cuts earlier this month. Equities have absorbed the hawkish reset, but a hot June CPI or PCE print would put that resilience to the test.
Single-name leadership is also narrowing in a way that warrants attention. Nvidia — which has functioned as the AI cycle’s lever — sold off Friday on the heaviest volume of any name on the most-active board. When the cycle leader rolls while the broader tape rips, the question is whether breadth is widening or the leader is topping. The next two weeks of earnings — including Nvidia’s suppliers and the rest of the hyperscaler customer base — will help adjudicate that.
What to watch next week
- The 9th week. A simple win-streak update: a green close Friday May 29 would be the longest weekly run in roughly three years and would put short positioning under pressure.
- Mega-cap follow-through. Does Nvidia hold the post-earnings range, or does the Friday slip extend? The cycle’s tape leader still sets the tone for risk appetite.
- Macro prints. The next inflation read (PCE) is the swing factor for whether the market gets to keep extrapolating rate-cut hopes — or has to take them out again.
- Speculation gauge. Quantum and small-caps are the cleanest tells for whether retail risk appetite is genuinely re-broadening or just chasing single-day catalysts.
