Current TMO snapshot

As of May 15, 2026, spot at $437.94, ATM IV 30.92%, IV rank 45.02%, expected move 8.87%. The bear put spread on TMO below is built from the same end-of-day chain, with strikes snapped to listed contracts and premiums pulled from the bid/ask midpoint at a 28-day expiry.

Why this bear put spread structure on TMO specifically: TMO IV at 30.92% is mid-range versus its 1-year history, so strategy selection should anchor more to the directional thesis than to the IV regime, with a market-implied 1-standard-deviation move of approximately 8.87% (roughly $38.83 on the underlying). The 28-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated TMO expiries trade a higher absolute premium for lower per-day decay. Position sizing on TMO should anchor to the underlying notional of $437.94 per share and to the trader's directional view on TMO stock.

TMO bear put spread setup

The TMO bear put spread below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With TMO near $437.94, the first option leg uses a $440.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed TMO chain at a 28-day expiry; the cross-strike IV skew is reflected directly in the per-leg values rather than approximated. Quantity sizing assumes one contract per option leg (or 100 TMO shares for the stock leg in covered calls and collars).

TMO thesis for this bear put spread

The market-implied 1-standard-deviation range for TMO extends from approximately $399.11 on the downside to $476.77 on the upside. A TMO bear put spread caps both the risk and the reward of a bearish position; relative to an outright long put on TMO, the spread reduces the cost basis but limits the maximum profit to the strike width minus net debit. Current TMO IV rank near 45.02% is mid-range against its 1-year distribution, so the IV signal is neutral; the bear put spread thesis on TMO should anchor more to the directional view and the expected-move geometry. As a Healthcare name, TMO options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to TMO-specific events.

TMO bear put spread positions are structurally moderately bearish; the modeled P&L assumes European-style exercise at expiration and ignores early assignment, transaction costs, dividends paid before expiry on the stock leg (when present), and the bid-ask spread on the listed chain. TMO positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move TMO alongside the broader basket even when TMO-specific fundamentals are unchanged. Long-premium structures like a bear put spread on TMO are particularly exposed to IV-crush risk through scheduled events (earnings, FDA decisions, central-bank meetings) where IV typically contracts post-event regardless of the directional outcome. Always rebuild the position from current TMO chain quotes before placing a trade.
