It's pretty straightforward, just buy a good cross section of an economy and you should do well over the long term. The market will be high in 10 to 20 years, and significantly higher in 30. It's almost impossible for a company with no debt to go bankrupt. The U.S. is about 50% of the global marketplace, Pay yourself first. It's time in the market, not timing the market. Last year I invested 200 grand in the S&P 500/ an allocation fund (with the help of my advisor Jane Marie Kunak of course) and it returned 370k, but guess what? I put it back and reinvested. Now I’m rounding up close to a million.
