U.S. equity markets delivered a split session Tuesday, with the tech-heavy Nasdaq Composite powering higher while the Dow Jones Industrial Average slumped, as investors digested a fresh batch of earnings reports and corporate developments against a backdrop of lingering geopolitical uncertainty.
The S&P 500, tracked by the SPY ETF, closed nearly flat at $773.37, down just 0.09%, after touching a high of $775.14. The Dow, represented by the DIA ETF, fell 0.86% to $517.92, pressured by weakness in industrial and consumer names. Meanwhile, the tech-focused QQQ ETF rallied 0.85% to $747.29, reaching an intraday high of $748.35. Small caps, as measured by the IWM ETF, slipped 0.19% to $287.13.
The Fear & Greed Index registered 78, firmly in "Extreme Greed" territory, suggesting investor sentiment remains buoyant despite the mixed tape.
## Sector Highlights
Technology led the charge, with the QQQ's gain underscoring renewed appetite for growth and semiconductor names. The sector was bolstered by anticipation around Micron Technology's upcoming earnings report, with one headline noting the stock "is still the cheapest in tech" despite expectations of a tenfold profit jump. On the downside, housing-related and consumer cyclical stocks faced headwinds, even as homebuilder KB Home delivered a beat. The Dow's decline reflected broader weakness in industrials and financials, with the SPY's flat close masking significant dispersion beneath the surface.
## Biggest Movers
The session featured extraordinary volatility in small-cap and micro-cap names, with several stocks posting triple-digit percentage moves.
JAGX skyrocketed 1,089.46% to close at $33.66 on massive volume of over 21 million shares, though no specific catalyst was provided in the data. RAIN surged 48.54% to $1.01 on volume exceeding 61 million shares, while TPST jumped 33.42% to $1.04. Other notable gainers included ZCMD (+32.59%), INDP (+32.30%), and EPSM (+27.74%).
On the downside, DCOY cratered 40.00% to $3.09 on heavy volume of nearly 64 million shares. TGL fell 34.49% to $2.08, and NFE dropped 23.69% to $8.15.
## Key Earnings
Several companies reported quarterly results that moved shares significantly.
KB Home posted a fiscal third-quarter beat, with adjusted EPS of $1.05 topping the $0.89 consensus estimate, while revenue of $1.297 billion edged past expectations of $1.294 billion. Despite the double beat, the company acknowledged a "weakening" housing market, and shares traded mixed.

Thor Industries shares rose after the company reported stronger-than-expected fiscal fourth-quarter sales. However, CEO comments that the "RV recovery never arrived" tempered enthusiasm, and the stock's gains were modest.
SunCar Technology Group disappointed, with Q2 EPS of $(0.01) missing the $0.02 estimate and revenue of $145.342 million falling short of the $154.200 million forecast.
Aytu BioPharma surged after reporting a Q4 EPS of $0.00, beating the $(0.33) loss estimate, while revenue of $16.106 million easily topped the $12.276 million consensus.
