Yiheng Capital Dumps 270,000 Planet Fitness Shares Worth $29.4 Million

Yiheng Capital Management fully exited its put option position in Planet Fitness during Q3 2025, closing 270,000 option-equivalent shares with an estimated quarterly-average trade value of $29.44 million and a reported 4.3420% shift in 13F reportable AUM; post-trade the firm holds 0 shares and the position had been 2.65% of prior quarter AUM. The move accompanies a broader portfolio downsizing — total fund AUM fell 39% quarter-over-quarter — and reflects an options strategy that did not become profitable despite modest Q3 weakness in Planet Fitness shares (PLNT price $107.11 as of 2025-11-13; TTM revenue $1.29B; TTM net income $205.8M). This is primarily a portfolio rebalancing/exit of a derivatives exposure rather than company-specific news likely to move PLNT materially.

Analysis

Market structure: Yiheng’s full exit of $29.44M in PLNT puts (270k shares equivalent) is economically small versus a national franchisor’s market cap and likely produced negligible structural change to Planet Fitness’s pricing power or franchising economics. Immediate winners are counterparties who bought the puts or realized premium; losers are the fund (realized loss or opportunity cost) and any leveraged holders of similar options if volatility compressed. The bigger structural signal is fund-level deleveraging — AUM down 39% QoQ and top holdings (NOAH $77.85M, BILI $39.85M, EDU $27.7M) are vulnerable to forced selling which can transiently depress mid-cap consumer and China-exposure names.

Risk assessment: Tail risks include a continued liquidation cascade at Yiheng triggering >10-20% price drops in its largest positions within 30–90 days, renewed China regulatory shocks hitting BILI/EDU/JD, or a membership slowdown for PLNT if consumer spending weakens (revenue risk >10% yoy). In days the PLNT option exit is immaterial; in weeks/months volatility and flows matter (watch next 13F and AUM updates); in quarters PLNT fundamentals (TTM revenue $1.29B, NI $205.8M, ~16% margin) drive valuation. Hidden dependencies: option gamma/short-interest in PLNT and cross-margin with other Yiheng positions could create correlated dislocations; catalysts include PLNT same-store sales, next-quarter membership metrics, and China macro or 13F filings.

Trade implications: Prefer directional exposure to PLNT via limited-risk options and relative trades against China/consumer tech names. Execute a small outright long (1–3% NAV) in PLNT equity or a 12-month 100/140 call debit spread to capture steady cashflow upside while capping cost; size on conviction and target +20–30% in 9–12 months. Employ a pair trade: long PLNT vs short BILI equal notional (1–2% NAV each) to hedge macro/flow risk from Yiheng-like liquidations. If willing to own PLNT at a ~10% discount, sell cash-secured puts 3–6 months out to collect premium.

Contrarian angles: The market may conflate options liquidation with a bearish thesis on the equity — exiting puts reduces synthetic short pressure and is not equivalent to selling shares, so PLNT downside risk from this event is likely overstated. Forced-selling risk in Yiheng’s other large positions (NOAH, BILI, EDU) is an underpriced catalyst; look for >20% mark-downs as buying opportunities rather than permanent impairments unless fundamentals change. Historical parallels: option position roll-offs by funds often create short-lived volatility but not lasting fundamental repricing for franchised, cash-flow generative companies. Unintended consequence: aggressive hedging into apparent weakness could leave catalysts for sharp mean-reversion if AUM stabilizes or PLNT prints resilient membership growth.

Key Decisions for Investors

• Establish a 1–3% NAV long position in PLNT (buy equity) with a 12-month target of +20–30% and a hard stop-loss at -12% from entry; rationale: recurring memberships, ~16% net margin, and reduced put/liquidity overhang.
• Implement a 12-month PLNT 100/140 call debit spread (buy Jan-2027 100C, sell Jan-2027 140C) sized to equal 1–2% NAV to cap premium spend while participating in upside if PLNT >140 within 9–12 months.
• Run a relative-value pair trade: long PLNT (1–2% NAV) vs short BILI (1–2% NAV) to hedge China/ad-driven downside and monetize likely forced-selling pressure in Yiheng’s China exposure over the next 30–90 days.
• If Yiheng’s AUM falls another >20% next quarter or its 13F shows >50% reduction in any single top-five holding, reduce exposure to that ticker by 50% within 10 trading days and redeploy into high-quality franchises (e.g., PLNT) or buy volatility selectively.
