Common questions

What does a collar protect against?
Downside below the put strike: no matter how far the stock falls, the shares can be sold at the put's strike until expiry.
What does a collar cost?
Often near zero: the call premium received offsets the put premium paid ('zero-cost collar' when they match). The real cost is the capped upside.
Who uses collars?
Holders of concentrated positions who want temporary, defined protection without selling the shares — common around uncertain events.

Educational model, not trade advice. Options involve substantial risk and are not suitable for every investor — read the OCC’s Characteristics and Risks of Standardized Options. Model values use Black-Scholes with your inputs (constant volatility, European exercise, no dividends) and will differ from live market prices.

Research and education only — not financial advice. TENKis not a registered investment adviser or broker-dealer and gives no personalized advice. Every call is impersonal — identical for all users, generated on a schedule from SEC filings plus a delayed/third-party price feed — may be wrong or out of date, and is not a recommendation to buy or sell any security. The operator and an affiliated trading operation may hold or trade the securities TENK rates; see Disclosures. Past performance does not guarantee future results. Do your own research.
