Sell to open creates a new short position - you're now the option seller collecting premium upfront. This is how covered calls and cash-secured puts work. You receive cash immediately but take on the obligation to buy or sell stock if assigned. Opposite of 'buy to open' which creates a long position.

Key Points

  • You collect premium immediately when you sell to open
  • Creates an obligation - you may be assigned to buy or sell shares
  • Close the position with 'buy to close' to exit before expiration
