Barb - thanks for taking the time for the shorting tutorial. Many investors who mostly play on the long side (myself included) do not know the nits and grits of regulations on shorting. So, it sounds like Depository Transfer Corp. and the other clearinghouses coordinate the borrow to make sure the aggregate short interest can't exceed the number of shares available on the borrow. That sounds pretty responsible so there can't be a multiplier effect (train wreck) from a small contraction of the number of shares available on the borrow. And the creation of additional float is limited to 1:1. In your example of 10,000 shares outstanding, 8,000 shares available to be shorted, then the maximum "float" could be 18,000 shares - not some theoretically unlimited number. So, from your example, if 7,200 of the 8,000 shares available for shorting were lent out, and then all of a sudden 2,000 became unavailable, the deficit has to be made up by holders of at least 1,200 shares by repurchasing in the open market. A few questions: 1. Who besides DTC keeps track of all this stuff? 2. Do brokerage firms have a more or less real time fix (from DTC and other clearinghouses) on the number of shares available to be borrowed? 3. If the answer to #2 is yes, of course they do, can this information be disclosed by the brokerage to an individual investor? 4. Is there any reason why changing shares from a margin to a cash account would not reduce the pool of available to borrow? 5. Do you have any insight into the urban myth that placing a GTC limit sell order on shares held in a margin account reduces in any way the borrow pool? TIA for suffering some of the ignorance expressed on this thread (mine definitely included). We are here on SI to share and learn. Appreciate you taking some time to help at least some of us be a little less clueless. Regardless of the present GSTRF situation, I think a lot of investors have learned recently that balancing a portfolio with a few shorts is a smart thing to do. Speaking for myself, I've always been a little nervous shorting without my eyes open in fears of getting Rambusized; but I would not hesitate to bet against some fundamentally overpriced stock if I could do enough DD to know I wasn't walkiung into some classic bear trap. Thanks again for your light-shedding.
