Most investment mistakes are caused by basic misunderstandings of the securities markets and by invalid performance expectations. The markets move in totally unpredictable cyclical patterns of varying duration and amplitude. Evaluating the performance of the two major classes of investment securities needs to be done separately because they are owned for differing purposes. Stock market equity investments are expected to produce realized capital gains; income-producing investments are expected to generate cash flow.

Losing money on an investment may not be the result of an investment mistake, and not all mistakes result in monetary losses. But errors occur most frequently when judgment is unduly influenced by emotions such as fear and greed, hindsightful observations, and short-term market value comparisons with unrelated numbers. Your own misconceptions about how securities react to varying economic, political, and hysterical circumstances are your most vicious enemy.

Master these ten risk-minimizers to improve your long-term investment performance:

1. Develop an investment plan. Identify realistic goals that include considerations of time, risk-tolerance, and future income requirements--- think about where you are going before you start moving in the wrong direction. A well thought out plan will not need frequent adjustments. A well-managed plan will not be susceptible to the addition of trendy speculations.

2. Learn to distinguish between asset allocation and diversification decisions. Asset allocation divides the portfolio between equity and income securities. Diversification is a strategy that limits the size of individual portfolio holdings in at least three different ways. Neither activity is a hedge, or a market timing devices. Neither can be done precisely with mutual funds, and both are handled most efficiently by using a cost basis approach like the Working Capital Model.

3. Be patient with your plan. Although investing is always referred to as long- term, it is rarely dealt with as such by investors, the media, or financial advisors. Never change direction frequently, and always make gradual rather than drastic adjustments. Short-term market value movements must not be compared with un-portfolio related indices and averages. There is no index that compares with your portfolio, and calendar sub-divisions have no relationship whatever to market, interest rate, or economic cycles.

4. Never fall in love with a security, particularly when the company was once your employer. It's alarming how often accounting and other professionals refuse to fix the resultant single-issue portfolios. Aside from the love issue, this becomes an unwilling-to-pay-the-taxes problem that often brings the unrealized gain to the Schedule D as a realized loss. No profit, in either class of securities, should ever go unrealized. A target profit must be established as part of your plan.
