Selling the put obligates you to buy stock at strike price A if the option is assigned.In this instance, you’re selling the put with the intention of buying the stock after the put is assigned.
When running this strategy, you may wish to consider selling the put slightly out-of-the-money. If you do so, you’re hoping that the stock will make a bearish move, dip below the strike price, and stay there. That way the put will be assigned and you’ll end up owning the stock. Naturally, you’ll want the stock to rise in the long term.
The premium received for the put you sell will lower the cost basis on the stock you want to buy. If the stock doesn’t make a bearish move by expiration, you still keep the premium for selling the put. This is one of the few instances when you can profit by being wrong about the direction of the stock.
Maximum Potential Profit
Potential profit is limited to the premium received from selling the put. (If the puts are assigned, potential profit is changed to a long stock position.)
Maximum Potential Loss
Potential loss is substantial, but limited to the strike price if the stock goes to zero. (If the puts are assigned, potential loss is changed to a long stock position.)
Break-even at Expiration
Strike A minus the premium received for the put.
Ally Invest Margin Requirements
You must have enough cash to cover the cost of purchasing the stock at the strike price.
NOTE: The premium received from establishing the short put may be applied to the initial margin requirement.
For this strategy, time decay is your friend. You want the price of the option you sold to approach zero. That means if you choose to close your position before expiration, it will be less expensive to buy it back.
After the strategy is established, you want implied volatility to decrease. That will decrease the price of the option you sold, so if you choose to close your position before expiration it will be less expensive to do so.
Don’t go overboard with the leverage you can get when selling puts. A general rule of thumb is this: If you’re used to buying 100 shares of stock per trade, sell one put contract (1 contract = 100 shares). If you’re comfortable buying 200 shares, sell two put contracts, and so on.
