You're savvy, far above average, and take a holistic view. You don't watch the stock tickers daily and over-react to headlines. You wait for something significant, like a geo political event. Meanwhile you're stuffing S&P and AMZN. You have some bonds (80/20?), but you're concentrated into the market a lo
