Current TMO snapshot
As of June 30, 2026, spot at $503.39, ATM IV 38.48%, IV rank 88.61%, expected move 11.03%. The cash-secured put 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 31-day expiry.
Why this cash-secured put structure on TMO specifically: TMO IV at 38.48% is rich versus its 1-year range, which favors premium-selling structures like a TMO cash-secured put, with a market-implied 1-standard-deviation move of approximately 11.03% (roughly $55.53 on the underlying). The 31-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 $503.39 per share and to the trader's directional view on TMO stock.
TMO cash-secured put setup
The TMO cash-secured put 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 $503.39, the first option leg uses a $480.00 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 31-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 cash-secured put
The market-implied 1-standard-deviation range for TMO extends from approximately $447.86 on the downside to $558.92 on the upside. A TMO cash-secured put lets a trader earn premium while waiting to acquire TMO at the strike price; the strategy is most attractive when the trader is comfortable holding the underlying at that level and IV is rich enough to compensate for the assignment risk. Current TMO IV rank near 88.61% sits in the upper third of its 1-year distribution, which historically reverts; this raises the bar for premium-buying structures and lowers it for premium-selling structures on TMO at 38.48%. 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 cash-secured put positions are structurally neutral to slightly bullish; 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. Short-premium structures like a cash-secured put on TMO carry tail risk when realized volatility exceeds the implied move; review historical TMO earnings reactions and macro stress periods before sizing. Always rebuild the position from current TMO chain quotes before placing a trade.
