Consider what happened if you actually held these 30 stocks (individual issues or through the Diamonds) since January 2000: After 6 1/2 years, you are now almost breakeven on a nominal basis. If you reinvested the dividends from the Dow, you would be up 12.7%.
On a real basis, adjusted for inflation, you are actually down 19%; With reinvested dividends, you are down around 9%.
If you were lucky enough to sell back in January 2000, and you instead simply placed the money in a cash fund (money market), you would be up ~20.87% on a nominal basis; On a real basis, you are up just under 2%."
During the same period of time (2000 - today), the Bucharest Stock Exchange Index (BET) rose by more than 5 times (adjusted for inflation)! Here's something we do beat the americans!:))
