Stock options vs index options
Unlike index contracts, FORTIS options are deliverable — positions held into expiry can result in physical settlement, so most traders square off before the final sessions. Liquidity concentrates in the near-month at-the-money strikes; quotes far out-of-the-money can carry wide spreads, so check LTP against the bid-ask before sizing. Results announcements, sector news and F&O ban-list entry are the three events that reshape this chain fastest — FORTIS's ban status is shown above and on the F&O ban list.
Using the levels
Treat 880 and 950 as the defended zone for this series, and confirm any breakout against fresh buildup rather than standing OI. For multi-leg positions on these strikes, the strategy builder imports this chain's live prices.
FAQs
What is the lot size for FORTIS options?
The current lot size is 775 — specifications have been revised recently, so we display the live value rather than a fixed number.
When do FORTIS options expire?
Stock options trade monthly series; the current series expires on 25 Aug 2026. Positions held into expiry are physically settled, so most traders square off in advance.
What does physical settlement mean for FORTIS?
In-the-money stock options held to expiry settle by delivery of shares, requiring full value or holdings. This is the main reason stock-option OI unwinds faster into expiry than index OI.
