Tax Stocks Loss

Is it too late to claim a tax loss of a stock purchased in 2008?
I bought shares in a company that has filed for bankruptcy since the beginning of the year. Is it too late to claim the loss of my 2008 income tax filing? I served for less than a year complete.
If the company went bankrupt in 2009, could not ask for their loss in 2008. You to show that the population has no value amortized. My agent is going to buy anything that a customer has to charge $ 1 to establish a loss.
