The week at a glance

The S&P 500 ended Friday -0.1% from its 52-week high. Volatility held steady across all five sessions, with the VIX moving from 15.3 after the opening session to 15.4 at Friday's close. Among stocks in the S&P 500, 70.6% rose over the course of the week. Across all the U.S. stocks EasyAlpha grades, including small caps, 47.2% advanced. Large-cap benchmarks held near record levels without broadening their foundation, leaving headline stability in place while broader market participation divided.

The week began with upward momentum before macro crosscurrents slowed trading. On Monday, stocks gained ground as artificial intelligence optimism, expectations for corporate earnings, lower bond yields, and falling oil lifted equities to record levels. That initial support gave way midweek as energy markets tightened. Equities faced pressure as crude oil prices jumped, weighing on crude-sensitive shares. Pressure on equities deepened as higher Treasury yields and rebounding oil weighed on stocks ahead of the release of Federal Reserve meeting minutes.

Selling concentrated in technology names on Thursday as an OpenAI revenue report weighed on semiconductor and chip stocks. Equities steadied on Friday as energy prices retreated when a statement regarding Iran eased near-term energy supply concerns, bringing respite to stocks and bonds. That pullback in crude helped the major indexes recover from their midweek dip and preserve their net gains for the five sessions.

For the five-day period, the S&P 500 finished the week +1.2%. That move is quiet for a week, sitting middling within its historical range against its own weekly record. Most of the benchmark's return came on Monday, when the index finished +0.7%. The rest of the week saw the S&P 500 trade in narrow bands, giving back small portions of Monday's advance before recovering into Friday's close. That quiet follow-through kept benchmark volatility low despite midweek swings in energy markets and bond yields. The Dow Jones Industrial Average ended the week +1.0%. The Nasdaq 100 closed the week +0.2%, restrained by Thursday's decline in mega-cap technology and chip makers. Outside the large-cap indexes, U.S. small caps closed the week -0.9%, diverging from large-cap peers across five subdued trading sessions.

Sector performance reflected the cautious tone beneath the headline index numbers. Utilities led the market, with its Select Sector SPDR fund ending the week +3.9%, though our sources show no reported driver for the advance. The absence of specific corporate or sector announcements left the group's gain isolated from the rest of the market. At the bottom of the sector table, Technology lagged all major groups, with its fund finishing -0.5% following the midweek selloff in hardware and semiconductor producers. Beyond equities, long-dated U.S. Treasuries finished the week +0.6%, an advance for the fund that reflected easing yields across long-term government debt. In digital assets, bitcoin closed the week -3.2%.

Dispersion across S&P 500 constituents measured 4.3 points. That spread was ordinary against recent weeks, neither unusually wide nor tightly bunched, yet individual corporate announcements produced wide swings. Within the S&P 500, PTC Inc finished the week +35.0% after Schneider Electric agreed to acquire the industrial software company for $205 per share in cash. Crown Castle ended +19.9% as tower operators advanced following news of a SpaceX spectrum acquisition. On the downside, Intel Corporation closed the week -12.3% amid broader technology weakness and developments concerning its work on the Terafab project. The Mosaic Company finished the week -11.1%. Across all the U.S. stocks EasyAlpha grades, Pacira BioSciences, Inc. finished the week +44.0% following an acquisition agreement by Viatris for $36.50 per share in cash. Across that same broader universe, ArriVent BioPharma, Inc. closed the week -40.9%. At Friday's close, 13 S&P 500 stocks marked new 52-week highs, while 8 reached new 52-week lows.

Next week marks the beginning of corporate earnings season, with 25 S&P 500 companies scheduled to report quarterly results. The reporting schedule includes JPMorgan Chase & Co, Johnson & Johnson, Bank of America Corp, UnitedHealth Group Incorporated.

How grades work →

A grade measures quality against the other companies in a sector, from historical data. It is not a prediction, not a price target, and not advice. A company can be graded A and still fall.
