Frequently Asked Questions

What is an Option Premium?

The premium is the price an option buyer pays to the option seller (writer) for the rights granted by the option contract. It is quoted per share, so one standard U.S. contract of 100 shares costs Premium × 100.

How does a Long Call option work?

A Long Call (Buy Call) is a bullish strategy. You pay premium for the right to buy stock at the Strike Price. You profit if the stock rises above Strike Price + Premium before expiration.

What is the risk of selling options (Short Options)?

Selling call options without owning the underlying stock (naked call) has infinite risk, because there is no limit to how high a stock price can rise. Selling put options has high risk, capped only if the stock falls to zero.

How is Stock Break-Even calculated?

For stock trades, Break-Even Price = (Total Buy Cost + Buy Commission + Sell Commission) ÷ Number of Shares.
