Current OSIS snapshot

As of May 15, 2026, spot at $206.47, ATM IV 48.90%, IV rank 53.49%, expected move 14.02%. The bear put spread on OSIS 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 34-day expiry.

Why this bear put spread structure on OSIS specifically: OSIS IV at 48.90% 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 14.02% (roughly $28.95 on the underlying). The 34-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated OSIS expiries trade a higher absolute premium for lower per-day decay. Position sizing on OSIS should anchor to the underlying notional of $206.47 per share and to the trader's directional view on OSIS stock.

OSIS bear put spread setup

The OSIS 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 OSIS near $206.47, the first option leg uses a $210.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed OSIS chain at a 34-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 OSIS shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Put	$210.00	$13.70

OSIS thesis for this bear put spread

The market-implied 1-standard-deviation range for OSIS extends from approximately $177.52 on the downside to $235.42 on the upside. A OSIS bear put spread caps both the risk and the reward of a bearish position; relative to an outright long put on OSIS, the spread reduces the cost basis but limits the maximum profit to the strike width minus net debit. Current OSIS IV rank near 53.49% is mid-range against its 1-year distribution, so the IV signal is neutral; the bear put spread thesis on OSIS should anchor more to the directional view and the expected-move geometry. As a Technology name, OSIS options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to OSIS-specific events.

OSIS 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. OSIS positions also carry Technology sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move OSIS alongside the broader basket even when OSIS-specific fundamentals are unchanged. Long-premium structures like a bear put spread on OSIS 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 OSIS chain quotes before placing a trade.
