Notable Friday Option Activity: BLSH, SMR, RDDT

Nuscale Power (SMR) saw unusually large options activity with 127,773 contracts traded (≈12.8M underlying shares), roughly 56.7% of its one‑month average daily volume, led by 23,071 contracts in the $16 call expiring Jan 2, 2026 (≈2.3M shares). Reddit (RDDT) logged 23,413 options contracts (≈2.3M shares), about 56.2% of its one‑month ADTV, with notable activity in the $230 call expiring Dec 26, 2025 (2,714 contracts, ≈271,400 shares). These flows represent concentrated call positioning and elevated speculative/volatility interest that could influence short‑term liquidity and implied volatilities for the two names.

Analysis

Market structure: Heavy call flow in SMR (23,071 Jan‑2026 $16 calls = ~2.3M shares, ~56.7% ADTV) and concentrated RDDT calls (2,714 Dec‑2025 $230 = ~271k shares, ~56.2% ADTV) implies dealers will materially hedge delta/gamma, creating mechanically higher bid pressure in the underlying in the near‑term. Winners are long‑options buyers, market‑makers capturing theta and hedgers selling stock; holders of tight borrow or short positions are at risk of squeeze and rising borrow costs. Liquidity may bifurcate intraday: spot moves faster than fundamentals while positions are being established.

Risk assessment: Near‑term tail risks include rapid vol crush if flows are spreads/rolls rather than directional buys — implied vol could drop 25–50% on position unwind within days. Regulatory or corporate catalysts (filings, secondary raises for SMR or Reddit governance/monetization news) could flip the directional trade; expect weeks–months sensitivity into Dec‑2025/Jan‑2026 expiries and fundamentals to dominate beyond 12 months. Hidden dependency: retail forum coordination (Reddit reference) can amplify gamma but is unstable; check borrowing rates and block trade prints for true intent.

Trade implications: Direct: establish small, defined long exposure to SMR (1–2% NAV) via Jan‑2026 $12/16 call spread to limit downside and target 40–60% return if SMR >$16 by Jan 2026; exit on 30% adverse move or IV collapse >30%. For RDDT, prefer a conservative calendar/diagonal (buy Dec‑2025 $230 calls funded by selling 1–3mth calls) to capture term premium and dealer gamma; limit to 0.5–1% NAV. Pair: long SMR equity vs short small‑cap or BLSH exposure (dollar‑neutral 1:1) to hedge beta.

Contrarian angles: Consensus treats volume as bullish — but this could be large speculative spreads, pinning, or dealer-driven liquidity provision that reverses on expiry; implied vol remains the key risk. Historical parallels: meme/flow spikes (2021) produced 40–70% intraday moves then mean reversion; if open interest concentration >50% of ADTV and borrow fee spikes >10% that’s a sign to de‑risk. Unintended consequence: rapid borrow rate increases could bankrupt levered shorts and then trigger regulatory scrutiny or halts, accelerating moves unexpectedly.

Key Decisions for Investors

• Establish a 1–2% NAV long position in SMR using a Jan‑2026 $12/$16 call spread (buy $12, sell $16) to cap downside; take profits at +40–60% or cut at −30% from entry, monitor IV and unwind if IV drops >25% within 10 trading days.
• Allocate 0.5–1% NAV to a RDDT diagonal: buy Dec‑2025 $230 calls and sell 1–3 month calls to fund premium; exit or roll if short‑dated calls fill >70% of premium or if underlying moves >30% adverse within 5 trading days.
• Implement a pair trade: long SMR equity (0.5–1% NAV) and short BLSH (0.5–1% NAV) to neutralize market beta while capturing idiosyncratic upside from options‑driven flows; close if spread tightens/widens by 20% or after 90 days.
• Do not increase exposure above combined 4% NAV until confirming: (a) options open interest for relevant strikes >30% of ADTV with persistent buying for 3 trading days, (b) borrow fee <5% (if shorting), and (c) no pending SEC/corporate filings announced within 30 days.
