Holding Dena Bank and Andhra Cements for more than three years...what to do now?

#1
I'm holding Dena bank([email protected]) and Andhra cements([email protected]) for more than three years. Now both are trading at Rs30 and Rs 8 respectively.

Total value at cost = 21,400/-
Total value at market = 12,674/-
Total loss = 8,728/-

So, please help me to decide whether I should hold it more or sell it out and buy any other shares to make-up the loss in future.
