Daily Close: Stocks slip as CPI and oil take center stage

The Bureau of Labor Statistics will release the July Consumer Price Index on Wednesday, August 12 at 8:30 a.m. ET, followed by July Producer Price Index data on Thursday at 8:30 a.m. ET.

What this means: inflation is the clearest near-term catalyst for rates. A hotter reading could push yields higher and extend pressure on growth stocks, while a softer print could ease that pressure and improve the backdrop for a rebound.

Oil stayed volatile as hopes for a U.S.-Iran agreement faded. Brent crude finished about 1.4% higher at $88.91 per barrel after trading near $90 during the session. Treasury yields remained elevated as investors balanced oil-driven inflation risk against caution ahead of CPI.

What this means: oil is acting as a second inflation input before the CPI release. If crude stays firm and yields rise with it, the market will have a harder time expanding valuations in rate-sensitive growth stocks.

Large-cap technology remained a source of weakness, while small caps outperformed and the Russell 2000 finished higher. That divergence matters because the S&P 500 and Nasdaq can look weak even while participation improves beneath the surface. Compared with the prior session, the market again showed a rotation rather than a one-direction selloff.

What this means: healthier breadth would be constructive if it continues after CPI. If small caps and cyclical groups roll over while mega-cap technology remains weak, the pullback would become more concerning.

The Nasdaq underperformed the other major indexes, reinforcing the recent pattern of pressure in large-cap growth. With yields still elevated and inflation data due Wednesday morning, the near-term question is whether technology can absorb another rates test without a broader breakdown.

Recent sessions have shown that the market can stay resilient even when the largest technology names are not leading, but that resilience depends on broader participation holding up.

Base case: CPI lands close enough to expectations that yields remain contained and the market consolidates near recent highs.

Upside-risk case: CPI comes in softer, Treasury yields fall and growth stocks regain leadership, opening the door to a quick retest of record territory.

Downside-risk case: CPI runs hot while oil remains elevated, pushing yields higher and broadening the selloff beyond technology.

The key point is that Tuesday's decline was modest and breadth was mixed rather than uniformly weak. Wednesday's inflation reaction will determine whether this remains a controlled pause or develops into a more meaningful reset.
