If the bashers are short 10,000 shares, the bashers musk keep enough assets or cash in their account to equal 150% of the value of that stock.
This is how the bashers get burned.
If the basher has 10,000 shares short and the share price goes up, he must add cash or assets to that account.
Example 10,000 AMD shares go up 10 cents. The basher must have either add cash or assets in that account to maintain the 150% value of AMD. In this case, it is $1,500. For a 50 cent increase, that would be $7,500.
If the basher does not have the assets or the cash in the account to maintain the 150% required balance, the broker will force him to buy back the AMD shares at this higher price.
The losses the bashers could have is unlimited while for those longs you do not have a loss until you sell and nobody can force you to sell UNLIKE the bashers who are short.
If the stock price was to shoot up even $1, the bashers would have to add $15,000 to his account.
Sentiment: Strong Buy
