10 Hot Stocks to Watch — Monday, October 12, 2026

Moderna rocketed 14% to $225 after positive Phase 3 melanoma data for its personalized cancer vaccine and reinclusion in the Nasdaq-100, marking a 663% year-to-date surge. Yet the stock trades 61% above Wall Street's $122.67 fair value, raising valuation concerns ahead of full trial results on October 24. Options markets show mixed conviction: heavy call volume at $220 (ITM) and $250 strikes contrasts with substantial put interest at $200 and $180, suggesting traders are hedging upside bets into the data release.

Zscaler shares jumped 7.8% to $233.73 following a strategic security partnership with IBM and Red Hat, coupled with reaffirmed fiscal 2027 guidance that sparked broader cybersecurity sector strength. The stock trades near 52-week highs with a low beta of 0.90, suggesting measured upside relative to market volatility. Options flow shows mixed conviction: heavy call volume at $235 and $230 strikes (Oct 2026) signals bullish positioning, but a 1.29 call-to-put ratio and meaningful put interest at $200 indicates hedging concerns. Watch the $240 level as near-term resistance.

Snowflake (SNOW) jumped 7.42% to $368.89 after unveiling its Agentic Marketplace Discovery tool, capitalizing on renewed investor appetite for AI-enabled analytics platforms. The options market is decidedly bullish: a 3.38 call-to-put ratio and heavy volume in October 2026 $370/$400 calls suggest traders are positioning for a sustained rally toward the $425 Street consensus. With the stock near its 52-week high of $384.56 and accelerating revenue growth outpacing peers like MongoDB, near-term resistance sits at $380–$390 before potential breakout to $400.

Datadog surged 7.1% to $293.26, touching its highest level since inception, after CIBC analyst Todd Coupland raised his price target by $35 to $315 while maintaining an Outperform rating. The upgrade reflects growing institutional conviction around the cloud monitoring platform's exposure to AI-driven workload demand and observability adoption. Options flow remains mixed with elevated put volume at $270 strike and call concentration near $300–$310 levels through mid-October, suggesting traders are bracing for volatility around the $315 resistance zone.

BioNTech gained 5.32% to $96.96, tracking a broader biotech rally sparked by the NIH's personalized cancer vaccine initiative. Options traders are heavily net-long, with call-to-put ratio at 1130x and concentrated volume in $100–$125 strikes across November and December expiries, signaling conviction above current levels. Morgan Stanley maintained an Overweight stance but trimmed its price target to $114, suggesting upside exists but incremental; watch the $105 call expiring mid-October as a near-term technical pivot.

Coinbase surged today following regulatory approval of its Coinbase Clearing LLC unit, enabling the company to clear fully collateralized crypto derivatives—a pivotal milestone reshaping institutional demand. The stock's beta of 3.34 amplifies broader crypto strength, with Bitcoin eyeing $400K. Options flow shows mixed conviction: call buyers are aggressively targeting $185–$192.50 strikes (October 2026), while puts near $170 suggest hedging around current levels. Watch the $185 resistance as institutional derivatives migration unfolds.

NIO shares fell 4.24% to $3.39 today, extending September's 18.9% slump even as Q3 deliveries jumped 25.4% year-over-year and the Onvo sub-brand crossed 200,000 units. The disconnect between fundamentals and price action has lit up the options pit: call volume exploded to a 10.43 call-to-put ratio, with 7,393 contracts chasing the $4.0 strike expiring October 16—a 18% move from current levels. Battery-swap records and retail accumulation suggest conviction, but European headwinds and proximity to 52-week lows ($3.37) present downside risk through mid-month expiries.

Amazon rose 3.29% to $262.43 on reports of a potential $7 billion acquisition of AI startup Decart, which specializes in chip-agnostic software—a strategic move to strengthen its custom silicon and cloud infrastructure. The options market is firmly bullish, with a 4.44 call-to-put ratio and massive volume in October 2026 calls; traders are particularly active in $260–$265 strikes, signaling conviction above current levels. Watch the $265 resistance for a sustained breakout; a deal close would validate the AI-infrastructure thesis driving tech higher.

Arm Holdings tumbled 3.27% to $266.28 as a Delaware jury deliberates a high-stakes patent dispute with Qualcomm that threatens the company's $4.9 billion licensing architecture. The options market mirrors investor anxiety: a heavy concentration of put volume at $100 (5,514 contracts) signals hedge positions against downside risk, while call skew above $300 remains muted despite the stock's 143% YTD rally. Jurors resume deliberations Tuesday; a Qualcomm victory could force Arm to restructure its core revenue model and reset valuation multiples that have priced in uninterrupted growth.

Visa climbed to $385.45 today, notching a 2.76% gain as the payments giant tests the upper bound of its 52-week range. Options traders are aggressively buying calls, with a 1.87 call-to-put ratio and heavy volume in $380 and $385 strike calls expiring October 16—signaling conviction above current levels. The put wall at $372.50 and $367.50 suggests downside support is priced in, with the market weighing bigger client rebates against Visa's premium valuation heading into a volatile earnings and election-driven week.
