If you dabble in individual stocks (specifically small-cap stocks), eventually one of your holdings will offer you a warrant. A warrant allows you to buy a set amount of shares at a set price within a certain time period. Warrants are issued to entice investors to buy into an equity or debt offering by the company (putting lipstick on a pig) or to allow existing investors to increase their equity stakes.

If you receive a warrant, you have a few options:

  1. You can exercise the warrant by coming up with the cash for the extra shares. You simply have to call your broker with instructions and the one time I did this, there was no charge for the service.
  2. You can sell the warrants just like a stock and you’ll incur a trading commission. Obviously, this option makes sense only if you can net more than the trading commission.
  3. You can let the warrant expire if you don’t want to increase your stake or if the gross proceeds are less than your trading commission.
