US equities are showing a sharper internal split as tighter financial conditions weigh on the broader market, while a small group of large technology stocks continues to support headline index performance. According to BlockBeats, rising US Treasury yields, a stronger dollar and higher oil prices have all contributed to the tightening backdrop. Morgan Stanley chief equity strategist Mike Wilson said the effect now resembles Federal Reserve rate hikes, but the pressure is falling mainly on ordinary stocks rather than the biggest names in the index. Data cited in the report showed the median S&P 500 constituent is down about 15% from its 52-week high, one of the weakest such readings since the dot-com bust. Over the past six months, the S&P 500 equal-weight index has lagged the market-cap-weighted benchmark by about 6%. Wilson also said the S&P 500 equity risk premium has fallen below zero, reducing the valuation appeal of stocks relative to US Treasuries. He added that the market strain is still centered on multiple compression rather than a clear deterioration in economic growth. Nominal GDP growth remains strong and corporate earnings are still expanding, but valuations could face more pressure if real rates continue to rise. Goldman Sachs, meanwhile, warned that US equity supply could rise sharply in 2027 as lockups expire.

US stocks are becoming more sharply divided as tighter financial conditions put pressure on the broader market, while a small number of large technology companies continue to hold up the headline indexes, according to BlockBeats on Oct. 17.

Rising US Treasury yields, a stronger dollar and higher oil prices have all contributed to the tightening in financial conditions.

Morgan Stanley chief equity strategist Mike Wilson warned that the effect now resembles Federal Reserve rate hikes, but the hit is landing mainly on ordinary stocks.

Broader market continues to lag

Data cited in the report showed that the median S&P 500 constituent is about 15% below its 52-week high, one of the weakest readings since the dot-com bust. Over the past six months, the S&P 500 equal-weight index has lagged the market-cap-weighted index by about 6%.

At the same time, the S&P 500 equity risk premium has fallen below zero, signaling that stocks have become less attractive on a valuation basis relative to US Treasuries.

Pressure is centered on valuation compression

Wilson said the current strain is coming mainly from valuation compression and has not clearly turned into an economic growth risk. Nominal GDP growth remains strong, and corporate earnings are still expanding, but market valuations could face more pressure if real rates keep rising.

Goldman Sachs also warned that US equity supply could rise sharply in 2027 as lockup expirations add to the market.

What the market is watching next

The next key signals will be whether financial stocks can stabilize and whether Treasury volatility starts to ease. From here, the market faces two possible paths: either ordinary stocks rebound and catch up with large technology names, or large technology stocks decline and pull the indexes closer to the broader market's weaker performance.
