Help reduce the amount of shares available to short, put a sell order on the shares you
put a sell order on the shares you own of Facebook at say double or triple the current stock price. This makes those shares unavailable to be shorted as they are "for sale" . Just dont forget to raise that sell price as the share price goes up! If i remember correctly there used to be an option with onlne brokerage accounts that you could click to make it so know one could short your shares.
Its not even about that. its about not letting the shorts use your own shares against you if you are long. In addition to, if there are less shares available to short it becomes more expensive for them to get a hold of a share.
Its a good idea folk. Here is a quote from a good article." Q.: What can you do to prevent your shares holdings from being shorted?
A: Now what can the average personal investor do to stop their own shares being shorted, as believe me your own broker, if approached, WILL sell your own shares that they hold on your behalf as a nominee account.
There are two things you can do, the first is to certificate them but this is not obviously to everyone’s advantage but the alternative solution is simple. All you do is to phone your broker and put an order in saying that you wish to place your shares for sale at, for arguments sake, double today’s price. As they are 'on order' they cannot be lent out by your broker and in turn you are reducing the amount of 'free shares' out there that can be used for shorting purposes. And don't forget to move your limit order up when the price starts to recover, then, that way your shares can't be shorted - not much but helps :D.
Although an individual personal investor will not normally have enough shares to halt a concerted shorting attack, if a large number of holders did this it would reduce the overall amount of shares that they could get their hands on.
In my opinion well worth doing if not only for the knowledge that your own shares cannot and will not be used in a short attack against the very share that you own."
