Highly effective do-it-yourself investors (HE DYI’s) beat the professionals…
…with mathematical certainty.
For over 100 years, the market has given the best investment returns.
Additionally, the constantly quoted prices, the low transaction costs, accurate records and the great liquidity make market investing attractive. The market is efficient which is the reason why it is nearly impossible to do better than the market itself in the long run (10 years or more). When management fees are subtracted, underperformance is a mathematical certainty. Happily, equaling the market returns is logical and straightforward. All that HE DYI’s do is to establish a personal asset allocation position and buy a broadly-based index exchange traded fund (ETF) which represents the US economy.
