10 Hot Stocks to Watch — Friday, September 18, 2026

Super Micro Computer jumped 9.5% Thursday as a rebound in high-beta AI hardware stocks accelerated following the Fed's hawkish pivot, lifting server makers alongside memory chips. Options markets are flashing aggressive bullish conviction: call-to-put ratio of 2.67 with heavy September 18 call buying concentrated at $36 and $40 strikes, now in-the-money. The street is watching whether SMCI can sustain momentum above $41 as competitors like Vertiv and Dell scale AI infrastructure revenue, though rising operational complexity amid component shortages poses execution risk.

Arm Holdings jumped 8.57% to $264.90 on bullish commentary from CEO Rene Haas regarding the chipmaker's artificial-intelligence revenue aspirations, even as demand outpaces manufacturing capacity. The options market is overwhelmingly bullish, with a 15:1 call-to-put ratio and heavy positioning in $300 calls expiring September 2026, signaling conviction in a sustained rally. Investors are pricing in upside toward $300–$320 over the next 12 months, though the stock's elevated 247x earnings multiple and reliance on mobile revenue rather than AI remain structural risks to monitor.

Moderna rocketed 8.55% to $158.07 after presenting bullish vaccine pipeline data at the Morgan Stanley Healthcare Conference, extending a stunning 137% monthly rally. Options traders are layering conviction: a 4.59 call-to-put ratio reveals heavy positioning in September 2026 calls, with 15,358 contracts at the $170 strike alone—all zero open interest, signaling fresh institutional accumulation. The stock now trades near 52-week highs with $165–$170 resistance emerging as the key battleground through mid-2026.

Intel climbed 7.67% to $108.80 on preliminary talks with SK Hynix to supply memory chips for its Ohio manufacturing hub—a potential validation of CEO Pat Gelsinger's costly turnaround bet. Options traders are pricing conviction: call volume hit 141k contracts with heavy 9/18 $110 and $112 strike demand, while the 1.98 call-to-put ratio signals aggressive upside positioning. Watch $110 resistance through Friday's expiry; breach targets $112 near-term.

AMD rallied 6.36% to $545.09 today as cloud-computing provider Nebius raised prices on its AI infrastructure, signaling durable demand for the chipmaker's data-center processors. Options markets are flashing aggressive conviction: call volume hit 109k contracts with a 1.87 call-to-put ratio, concentrated in near-term $550 and $555 strikes expiring September 18th. Bullish positioning suggests traders expect AMD to maintain momentum through month-end, though the stock sits near its 52-week high of $584.73.

Coinbase rallied sharply today as CEO Brian Armstrong signaled momentum beyond the failed Clarity Act, pivoting toward SEC/CFTC rule-making under existing authority. The options market is heavily bullish, with call volume crushing puts at a 1.83 call-to-put ratio; September 2026 calls at $170, $175, and $180 strikes are trading exceptional volume, suggesting institutional conviction above current levels. Watch the $180 resistance—if cleared, bulls are positioned for a deeper move into year-end as tokenized stock frameworks and agentic trading gain traction.

Oracle rallied 5.19% today as cost-reduction efforts bolster its $664 billion infrastructure backlog, though persistent negative free cash flow tempers enthusiasm. Bullish options positioning—a 1.80 call-to-put ratio with heavy 2026 call buying above spot—signals traders expect the stock to challenge $155–$160 within 18 months. Project Jupiter's regulatory clarity provides near-term support, but capital intensity remains the overhang; watch whether Q3 earnings can reconcile cloud growth with cash generation.

Robinhood climbed 5.16% to $109.81 following the SEC's green light for blockchain-based stock trading, positioning the platform as a potential beneficiary of tokenization infrastructure. Options traders are voting decisively bullish, with a 5.87 call-to-put ratio and outsized volume in $110–$120 calls expiring September 2026, suggesting conviction in a sustained move higher. Street target sits near $129, leaving room to $115–$120 on near-term strength.

Marathon Digital surged 4.81% today, extending a 21% monthly gain after the $100M Bitcoin acquisition via FalconX signaled deeper crypto exposure. Options markets are flashing conviction: the 3.51 call-to-put ratio reflects heavy September 2026 call buying, with 20,704 contracts at the $11.50 strike already in-the-money and 18,976 contracts queued at $12.00. Regulatory risk lingers—the Senate's pending Clarity Act vote could reshape crypto oversight—but the bullish options flow suggests traders are pricing upside toward the $12–$12.50 band before year-end.

VXX fell 3.80% today as the Cboe Volatility Index plunged 11% on renewed risk appetite, yet options traders are signaling conviction in higher prices ahead. Heavy call buying—evidenced by a 7.58 call-to-put ratio—has flooded September 2026 contracts, with $21 and $21.50 strikes commanding 3,000+ volume each despite zero open interest. The positioning suggests traders are hedging against macro uncertainty persisting beyond near-term relief, particularly around lingering inflation concerns and geopolitical tensions that have kept oil elevated.
