Dear Mr. Berko: In 2007, my stockbroker had me buy 100 shares of J.C. Penney at $73. Months later, he had me buy another 100 shares at $62. And because he was very certain it would recover, he had me buy 100 more shares when it had fallen to $47. Finally, in 2009, I bought my last 100 shares at $28, giving me an average cost of $52.50 per share. I still own the stock and want to know whether I should sell my 400 shares or buy the stock again at $1.36 a share.
