Worked as a photoengraver for 34 years. My first purchase was 30 shares of Pacific Petrolium for $18/share in 1967. It went up to the mid forties and I sold it for $18/share. That should have been an alert. My nest purchase was mutual funds for a 401k in the 1980s. Then started buying common shares in the late 90s. I thought there must be a science or method to this, then one day at TDAmeritrade my account manager asked if I’d like take a class in Investools.
