Payoff Profile

The collar creates a 'floor and ceiling' on your stock position. The protective put establishes a floor (minimum selling price), while the covered call creates a ceiling (maximum selling price). Your profit/loss is bounded between these two levels. • Put strike - guaranteed minimum exit price • Call strike - maximum profit level (stock called away) • Between strikes - stock moves normally, you keep gains/losses • Often zero-cost (put premium offset by call premium)

Frequently Asked Questions

Can I collar a stock I just bought?

Yes! You can buy stock and collar it simultaneously. Some traders do this for new positions where they want defined risk from the start. Just ensure you own the stock before the collar settles.

What happens to my dividend when I have a collar?

You receive dividends normally because you own the stock. However, be aware that ITM calls may be assigned early before ex-dividend, causing you to lose the stock (and dividend). Monitor calls before ex-dates.

Do I have to keep the collar until expiration?

No, you can close the collar anytime by buying back the call and selling the put. You'd be left with unhedged stock. This is useful if protection is no longer needed or you want to take a different approach.

What if I don't have 1,000 shares?

Standard Singapore equity options require 1,000 shares per contract. If you own fewer shares, you cannot create a perfect collar. You'd need to buy more shares or use alternative hedging (e.g., CFDs with stops).

Is collar better than stop loss?

Different tools. Collar: Guaranteed floor, costs opportunity (call ceiling), works even in gaps. Stop loss: Free, no ceiling cap, but can gap through in fast markets. Collar is better for guaranteed protection; stop loss is simpler for basic risk management.

How do I calculate the effective floor and ceiling prices?

Floor = Put Strike - Net Premium Paid (if debit). Ceiling = Call Strike + Net Premium Received (if credit). For zero-cost: Floor = Put Strike, Ceiling = Call Strike. Adjust for your stock entry price to get total P&L.

Should I roll collars or let them expire?

If stock is between strikes: Both expire worthless - roll if want continued protection. If at ceiling: Likely called away - accept or roll call up. If at floor: Put exercised - exit or roll put down. Roll 1-2 weeks before expiration to maintain protection.

How does IV affect collar cost?

High IV makes both options expensive. BUT, it's often easier to achieve zero-cost because call premium is also elevated. Low IV makes protection cheaper, but you get less call premium. High IV is often better for zero-cost collar construction.

Can I collar an ETF like STI ETF?

Yes, if options are available on the ETF. STI ETF options exist. Note ETF contract sizes may differ (often 100 shares). The principle is identical - own ETF, buy put, sell call.

What if I want protection but not willing to cap upside?

Use a protective put only (married put). You pay for the put without selling a call. No ceiling on gains, but costs money upfront. Collar trades ceiling for zero-cost; protective put keeps unlimited upside but costs premium.

How does skew affect collar strike selection in practice?

Put skew (OTM puts having higher IV) makes equal-distance collars cost money. To zero-cost, you typically need the call 2-5% closer to ATM than the put. Example: 10% OTM put might need 7% OTM call. Measure IV at each strike to optimize.

What's the optimal collar duration?

Depends on purpose. Event protection: Match event (weekly/monthly). Ongoing protection: 30-90 DTE with rolling. Longer-term collars (6-12 months) reduce rolling but tie up more premium. Most practitioners use 45-60 DTE with monthly rolling.

How should I collar a concentrated executive stock position?

Staged collaring: Collar 25% of position now, another 25% in 3 months, etc. Use different strikes/expirations. Consider costless collars with equity prepaid forwards or other structured products for very large positions. Consult specialized advisors for regulatory/tax issues.

Can I synthetically create a collar without owning stock?

Yes - synthetic collar = Long call + Long put + Short call at higher strike = Bull call spread + put. But this defeats the purpose of stock ownership. More common: Collar-like risk reversal structures without stock. However, standard collar assumes stock ownership.

How do margin requirements change with a collar?

Collar reduces margin requirement. The protective put limits risk, so brokers recognize defined max loss. Your margin on the collared stock is lower than naked stock. This frees up margin for other positions - a hidden benefit of collars.
