Please require serialization of every share of stock traded on any US exchange, including ADRs. If you buy 45 shares of stock ABC, you should receive with your purchase confirmation a list of 45 share numbers which serve to uniquely identify the exact shares that you bought for company ABC.

Also, enforce the law with respect to Reg SHO violators. We need some serious prison terms handed out.
