Protective Puts Explainer
A protective put combines owned shares with a long put that grants the right to sell them at a chosen strike. The structure preserves upside in the stock while establishing a temporary floor, subject to the premium and contract terms.
At expiration, the approximate maximum loss equals the stock purchase price minus the put strike plus the premium, before dividends, fees, and taxes. A higher strike creates a tighter floor but usually costs more; a later expiration extends protection and also tends to raise cost.
The put can be sold rather than exercised if it retains time value. Early exercise may sacrifice that value. If the hedge uses a different underlying, contract size, or expiration from the asset being protected, basis and sizing mismatches can leave uncovered risk.
Insurance is not free. Repeated put purchases can reduce long-run returns, and implied volatility often rises when protection is most desired. Investors should compare the hedge with position reduction, diversification, collars, and explicit loss limits rather than assuming every portfolio needs continuous coverage.
