Riskless Transaction

A transaction where a gain is guaranteed by the structure of the transaction. To give a very simple example, one may find a client who wishes to purchase a security at $10 per share when one knows that the current price is $9.50 per share. One then buys the security at the current price and instantly re-sells to the client for a 50 cent per share guaranteed profit. This is also called a simultaneous transaction.
