Sometimes a stock pops up in your monthly account statement from your broker and you have no idea where it came from. Sometimes you remember owning a stock but you don't know what happened to it!
Many people are also confused about what type of reorganization action their stock had and which calculator to use.
This master stock lookup tool can help you identify the origin or disposition of a stock and which calculator you need to use to compute your cost basis.
Where there have been stock splits or return of capital adjustments, the stock lookup tool will also alert you to adjust for that.
The database of the stock lookup tool is not complete. We are continually adding to our free database of stock information for your benefit. If you have corporate mergers, spinoffs, stock splits, or return of capital information that you can contribute, please send the details to us.
If you are looking for a corporation action that is not in our database, please submit as much information to us as possible on the Reorg Info page of our website. We will analyze the event and add it to our database for you to use in the calculators.
