Stocks are under pressure Tuesday as a jump in Treasury yields reasserts itself as the primary market driver, sending long-duration growth names lower. The NASDAQ is off 1.14% to 26,423, roughly triple the S&P 500's 0.40% decline to 7,754.94, while the Dow is essentially flat at 53,712 (-0.04%). The divergence tells the story: rate-sensitive megacap Tech is bearing the brunt, with the sector down 2.37% pre-market on weakness in AMD (-5.12%), MSFT (-2.56%), AVGO (-1.77%) and NVDA (-2.00%). The intraday tape confirms the risk-off character, with NQ showing its usual tight -0.84 inverse correlation to the VIX and a +0.80 pull with the ES.

Sector positioning reflects a textbook defensive rotation. Energy leads decisively, up 2.17%, as fading optimism around a near-term US-Iran peace deal keeps a geopolitical premium embedded in crude; XOM (+2.41%), VLO (+2.67%), CVX (+2.25%) and COP (+1.67%) are all higher even as front-month crude ticks down 0.25% to $84.29. Healthcare (+0.70%) and Utilities (+0.39%) round out the green, with JNJ (+1.98%) and ABBV (+1.14%) drawing safe-haven flows. Gold's 0.84% advance to $4,454.90 underscores the cautious tone. On the other side of the ledger, Communication Services is down 1.83%, dragged by META (-4.71%), while Industrials (-1.06%) are pressured by BA (-2.66%).

The morning's data slate offered a mixed housing picture. Housing Starts disappointed at 1.239M, a steep -12.4% MoM plunge that badly missed the -4.7% consensus, but Building Permits surprised to the upside at 1.443M, a 5% monthly gain versus the 1.2% forecast — suggesting the starts drop may prove noisy. Import and export prices both came in soft (import prices -0.4% MoM, export prices -1.3% MoM), reinforcing a benign inflation-goods narrative even as bond yields press higher. Later today, markets get Industrial Production (F: 0.3%) and Pending Home Sales at 2:00 PM ET.

The near-term catalyst calendar is front-loaded around the Fed. Wednesday brings the FOMC minutes at 6:00 PM ET, and prediction markets are leaning decidedly hawkish: Polymarket assigns an 85% probability to no rate cuts at all in 2026, and notably prices a 28% chance of a 25 bps hike at the September meeting versus just 1% for a cut. That repricing dovetails with the current yield backup and helps explain why the highest-multiple corners of the market are the most vulnerable. Beyond the minutes, focus shifts to the Jackson Hole Symposium beginning August 27 and the August 26 PCE report (Core PCE F: 0.3% MoM).

Bottom line: this is a rates-driven, rotational pullback rather than a broad-based liquidation. With the Dow holding near unchanged and Energy, Healthcare and Utilities catching a bid, the pain is concentrated in Tech and Communication Services, where the yield backup is doing the most damage. Traders should watch the 7,750 area on the S&P 500 and monitor whether the yield move extends into Wednesday's FOMC minutes, which now stand as the week's key risk event alongside a geopolitically charged energy complex.
