Just as 李兆基 increase the shares of HK and China Gas constantly these days, it caught my attention of "buybacks" again. Before I read the book about Warren Buffet. He liked to buy those stocks that the company will buy back its own shares, so that the values of his shares will be increased. Also, just read an article in Fortune about the issues of buyback of shares. It said usually it meant the price of the shares are undervalued. So does that mean the price of the stocks of HK and China Gas are undervalued?
