Analysis

US equity futures firmed into Friday's open, with the S&P 500 and Nasdaq reclaiming key levels and Investor's Business Daily flagging flash buy signals in Moderna (MRNA), AMD, and SpaceX (SPCX). Semis led the move: Intel (INTC) was the market's top volume name, up 7.67% to $108.80 on roughly 149.7 million shares, after TheStreet reported SK Hynix (SKHY) has a $4 billion problem Intel could help solve. Super Micro (SMCI) rose 9.5% to $40.35 and Nvidia (NVDA) added 2.54% to $219.34 on 94.2 million shares, with Stocktwits noting INTC, AMD, MU, and NVDA rallying as investors look past AI concerns. SpaceX-adjacent SPCX climbed 2.6% to $154.81 on about 84 million shares, even as retail sentiment in satellite rival ASTS nears a 1-year low as SpaceX turns up the heat in the global mobile race. Corporate capital deployment was the day's other strong theme. Generac (GNRC) spiked 18.34% to $207.23 after Amazon (AMZN) announced an $8 billion backup power deal, on top of a separate $1.5 billion move for US workers; JPMorgan committed $750 billion to rebuilding America's housing supply and Coca-Cola (KO) plans $10 billion of US investment through 2030. Sandisk (SNDK) unveiled a $14 billion buyback that drew commentary from Warren Buffett (Motley Fool), and in autos one analyst says Tesla (TSLA) trades about 20% below fair value even though retail stays bearish amid Cybercab scrutiny and SpaceX merger buzz. The tape is not uniformly green. DSP fell 19% to $10.02 and FLNC slid 15.36% to $7.66 on 33.8 million shares; PEP, LULU, and ONON all tumbled to 52-week lows, and Exxon Mobil's (XOM) CFO warned of hidden risks behind the oil supply shock. The technical scan of 2,593 symbols leans defensive going into the session: 31 bearish signals versus 17 bullish, with TPC flagged for potential overextension at $85.67 and MRNA overbought at $158.07, while bargain hunters circle oversold names like SION at $7.18. SDGR was the session's biggest winner, jumping 26.37% to $30.24.

Constructive but selective: futures have reclaimed key levels on a semis-led rally (INTC +7.67% to $108.80, SMCI +9.5% to $40.35, NVDA +2.54% to $219.34), while AI-infrastructure capex keeps generating catalysts in AMZN's $8B Generac power deal, JPM's $750B housing commitment, and SNDK's $14B buyback. The risks sit at the edges of the tape — oversold momentum names (DSP -19%, FLNC -15.4%), 52-week lows in staples (PEP, LULU, ONON), a signal scan that leans bearish (31 vs 17), and Exxon's warning on hidden risks in the oil supply. Favor large-cap semis and AI power infrastructure into the session, with defensive pockets in dividend names, but treat MRNA's overbought flag at $158.07 as a reason to avoid chasing the biotech flash buy signal.
