What I like about the approach is that product is a leading indicator and can be judged by anyone. The financials and stock price seem to trail the product by 1-3 years on both the upside and downside.
BTW I fully agree with the original premise of the thread and think if you try actively trade on financials, timing etc. as a part timer you will get smoked by the pros, sooner or later.
On a positive note, the proceeds paid for my honeymoon and the balance went into Apple and Red Hat, both of which did good!
The 90s were fun and a learning experience. I was working in the mall while going to school, feeling like a financial genius for day-trading at a DSL kiosk at lunch. Amazon was money lost, but also money gained!
I rolled a couple thousand dollars into many multiples of paper profit. I pulled some out occasionally and put it in savings bonds, thanks to the constant nagging of my grandparents, so everything I lost was money I never really had.
