What is the breakeven for a TRI long put?

The breakeven for the TRI long put priced on this page is roughly $70.30 at expiration, derived from end-of-day chain premiums. Breakeven is the underlying price at which the strategy's P&L crosses zero ignoring transaction costs and assignment risk. The current TRI market-implied 1-standard-deviation expected move is approximately 14.39%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.

TRI ATM IV is at 50.20% with IV rank near 71.05%, which is elevated relative to its 1-year range. Premium-selling structures (covered call, cash-secured put, iron condor) generally look more attractive when IV rank is high; premium-buying structures (long call, long put, debit spreads) are more expensive in that regime.

Current TRI snapshot

As of May 15, 2026, spot at $82.57, ATM IV 50.20%, IV rank 71.05%, expected move 14.39%. The long put on TRI 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 217-day expiry.

Why this long put structure on TRI specifically: TRI IV at 50.20% is rich versus its 1-year range, which makes a premium-buying TRI long put relatively expensive in absolute-cost terms, with a market-implied 1-standard-deviation move of approximately 14.39% (roughly $11.88 on the underlying). The 217-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated TRI expiries trade a higher absolute premium for lower per-day decay. Position sizing on TRI should anchor to the underlying notional of $82.57 per share and to the trader's directional view on TRI stock.

TRI long put setup

The TRI long 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 TRI near $82.57, the first option leg uses a $85.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed TRI chain at a 217-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 TRI shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Put	$85.00	$14.70

TRI thesis for this long put

The market-implied 1-standard-deviation range for TRI extends from approximately $70.69 on the downside to $94.45 on the upside. A TRI long put expresses a directional view that the underlying closes below the strike minus premium at expiration, frequently sized to hedge an existing long TRI position with one put per 100 shares held. Current TRI IV rank near 71.05% 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 TRI at 50.20%. As a Industrials name, TRI options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to TRI-specific events.

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