As investors, we want to believe we are smart, insightful and uniquely talented - even though we often fail to do the heavy lifting, put in the long hours, and make the uncomfortable but necessary decisions to achieve success.
Commissions add up, taxes are a big drag, margin ain't cheap. A good accountant costs money as well. The math on this one is obvious, yet investors often fail to recognize it: Keep your costs low and your turnover lower, and you will win in the end.
You, your employer and your plan's investment managers fail to follow even the most basic rules of investing. You overtrade, chase performance, do not think long term. All of you - All Of You - have done a horrible job managing your retirement plans.
