What are the potential upside and downside scenarios if the FDA approves or rejects TNX‑102 SL, and how should position sizing be adjusted accordingly?

Upside / Downside Scenarios

Approval – If the FDA clears TNX‑102 SL (the first new fibromyalgia therapy in 16 years), the drug’s ~10 M‑patient U.S. pool and the “first‑in‑16‑years” narrative give the stock a classic “breakout‑catalyst” profile. In comparable biotech approvals (e.g., Sage Therapeutics, 2022) the market has rewarded the lead‑stock with 30‑45 % gains on the announcement day, often pushing the price above the next major resistance level (the 52‑week high or the $X / $Y technical pivot that now sits a few cents above today’s close). A successful filing also opens the door to partnership or licensing deals, which can add another 10‑15 % upside on the forward‑looking valuation.

Rejection – A negative decision would strip the “first‑in‑16‑years” premium and force the market to re‑price the drug’s commercial potential. Historically, a PDUFA miss for a mid‑cap biotech triggers a 20‑30 % sell‑off, often breaking the nearest support zone (the $A‑$B range that has held since the Q2 earnings release). The downside is amplified by the fact that the company has no other near‑term revenue drivers, so the price could linger near the $C low until the next clinical milestone.

Position‑Sizing & Risk Management

Because the PDUFA date (Aug 15 2025) is a binary event, the trade should be treated as a high‑volatility, low‑probability bet. A prudent approach is to allocate ≀1 % of total capital to a directional position (long on approval, short on rejection) and set a tight stop just inside the technical support level identified above (e.g., 5‑7 % below the entry price). If implied volatility is still modest, consider a long‑call/long‑put straddle or a protective put on the downside to cap loss while still capturing the upside move. Scaling in—e.g., buying 50 % of the intended stake a few days before the PDUFA and the remainder after the first price reaction—helps avoid over‑exposure to the “flash‑crash” that often follows FDA news. Adjust the final size upward only if the stock shows a clear, sustained breakout (closing above the resistance with volume >1.5× average) before the decision, otherwise keep the exposure minimal.
