Certing Shares, You have to call the broker where your stock is and ask for paper certificates. It will cost something Ameritrade is 40 bucks, (the last time I asked. You give up liquidity but can sell if you need to by overnighting in the "certs" to your broker with the sell order. Or send them in to be credited back to your account if you intend a planned sale...
Shares in an IRA can not be "certed" as this violates the hands off rule by the IRS. If you "cert" in an IRA you may be subject to a tax penalty to do so. Placing shares in a cash account with a sell order will keep broker from using them (different brokers have different rules).
I have heard that some brokers will honor a stipulation from you if you ask that your shares not to be used for shorting. I don't know if that is true or not.
My shares are not certable as they are in an IRA....call me crazy, but I believe RX will be a sucess.
