Finding spin-off stocks to consider investing in can be accomplished by using keywords in a

• a news search
• a blog search
• a web search
• setting up alerts
• and/or looking at the list of current holdings of the Claymore/Beacon Spin-off ETF  ( CSD )  which includes more than enough names for further research and you may even decide to just let them do the work  by buying the ETF.

Once you have the best list of stock spin-off situations you can find, you will want to go through the same steps listed above with each company and the parent that you found so that you can keep track of how the spin-off is progressing. 

Also, with the stock symbols in hand it is much easier to find the appropriate SEC filings.  You can do that on the SEC website,  but I find that it is usually easier through the parent company’s website.   (You end up in the same place, but it’s usually easier getting there.)
