I reread the classic Common Stocks and Uncommon Profits by Philip A. Fisher. The original edition was published in 1958 and is still as relevant today. The book is ranked up there among the best investment book of all-time. It’s worth picking up once in a while to reread certain sections. I have the updated edition, which includes the perspectives of the author’s son Ken Fisher, a respected investment guru in his own right. You can find some of Ken’s writing at Forbes and books at Amazon.
