For what it's worth, SSF's offer opportunity for those long term traders who are bullish - especially those hard to borrow names. For example - if you are bullish SEED (hard to borrow), you can buy the SSF future that expires in Dec (into stock) for a .30 discount and yet no one does. If you're bullish for at least 18 days and have no access to lending your shares - then why wouldn't you prefer to buy the SSF at this substantial discount over the equity? The downside is that you can't easily get out of the product at a good price for at least a few weeks. It's says quite a bit about the markets when there is no volume traded on these SSF's.
