My account is based on two levels: 1) broad index etf's (which is the core of my portfolio, consists of 75% of my investments); 2) fundamental analysis, where I pick "best of breed" stocks and wait for discounts in price.
Retired primary schoolteacher- 3 years Daytrader. I still get sympathy cards rom Scottrade, but haven't missed too many bells, anyway.
