Fisher Investments created The Eight Biggest Mistakes Investors Make™ to help investors identify and avoid costly mistakes. Understanding these eight mistakes can greatly improve an investor’s ability to reach their long-term investing goals and objectives.

Below we explore each of The Eight Biggest Mistakes Investors Make™ in more detail.

  • Biggest Investor Mistake #1:

    Not Having Clear Investment Objectives or an Appropriate Time Horizon

    People often invest without clear investment objectives or an appropriate time horizon, focusing instead on short-term returns and price swings. Investors who don’t have clearly defined investment goals over an appropriate investment time horizon are much more likely to have “knee-jerk” reactions to short-term market events. That means they have to rely on luck to achieve their goals rather than a portfolio strategy with a higher probability of success.

  • Biggest Investor Mistake #2:

    Underestimating the Time Horizon for Your Assets

    Investors often underestimate how long their portfolio will need to provide for them. Given rapid advances in health care and nutrition, people are simply living longer today than decades ago, which means their money needs to last longer. Having an accurate sense of life expectancy can mean the difference between investing success and failure. One of the primary drivers of a successful portfolio strategy is the ability to accurately identify the investment time horizon, or the amount of time an investor’s assets need to be working.

  • Biggest Investor Mistake #3:

    Ignoring the Impact of Inflation on Your Portfolio

    Investors all too often focus on the dollar value of their portfolios without considering their purchasing power. Over time, a portfolio’s purchasing power can diminish due to inflation. Since 1925, inflation has averaged about 3% per year,* though it does fluctuate over time. It can rise dramatically, as seen in the mid-1970s and early 1980s, or it can be relatively subdued, as it has been this past decade. If we assume prices continue their long-term trend and rise about 3% per year for the next 30 years, an investor who currently requires $50,000 to cover annual expenses will need approximately $67,000 in 10 years, $90,000 in 20 years and about $120,000 in 30 years just to maintain the same purchasing power**.

  • Biggest Investor Mistake #4:

    Turning Away From a Long-Term Investing Strategy After Suffering Losses

    After a correction or bear market, some investors may be tempted to abandon stocks once they “get back to even.” Such emotional decisions can be harmful because they remove the focus from achieving their investing goals. In times like these, it’s especially important that investors stay focused on their long-term strategies. Prudent investors know stock markets can sometimes be bumpy and unsettling. However, historically, that volatility has come with a benefit—stronger long-term returns relative to bonds. Since 1926, the stock market has returned about 10% a year on average.*** This includes both bull markets AND bear markets. Though remaining calm during volatility can be challenging, capturing market moves above previous highs is essential to achieving long-term stock market gains.

  • Biggest Investor Mistake #5:

    Improperly Judging Risk

    Many investors improperly judge risk. Generally, the longer the time horizon of your investments, the more risk that may be appropriate, depending on your cash-flow needs and return objectives. Increased risk can allow for increased returns over the long term. But overly conservative portfolios can underperform.

  • Biggest Investor Mistake #6:

    Avoiding Foreign Securities

    Most investors know it’s smart to diversify, yet most American investors aren’t nearly as diversified as they think. A portfolio with only US stocks misses out on an important factor—the rest of the global stock market. American investors tend to focus on US stocks. However, investing only in US stocks may cause investors to miss out when foreign stocks outperform US stocks, a particular challenge for investors who rely only mutual funds.

  • Biggest Investor Mistake #7:

    Making Investments Based Only on Widely Known Information

    Many investors regularly read various newspapers, magazines and newsletters. Unfortunately, countless hours spent researching may not help you beat the market. Why? Because capital markets efficiently price in all widely known information. As soon as news is available to the public, it becomes reflected in share prices. So looking at the same thing as everyone else doesn’t give investors a leg-up on other investors. Despite this fact, many investors still make trading decisions based upon widely known information. That’s not to say news should be ignored. Rather, in order to beat the market over time, we believe investors must either know something most others don’t or interpret widely known information differently and correctly. This unique knowledge and insight can enable you to take advantage of things others miss.

  • Biggest Investor Mistake #8:

    Forgetting the Importance of Supply and Demand

    Pundits, economists, analysts and journalists all have theories on what factors will move stocks. But often the most fundamental factors determining stock prices go unnoticed: supply and demand. Basic economic theory states supply and demand for any asset traded in a free market will determine prices. Though this fundamental can be easy to overlook, it’s vital for understanding stock movements. Consider the bull market in the late 1990s. At that time, demand surged as investors clamored to purchase stocks. Initially, stock supply remained relatively steady, and stock prices rose. But in late 1999 and early 2000, a huge influx of stocks came to market through initial public offerings (IPOs). The new supply overwhelmed demand, stock prices fell and a bear market ensued. After the bear market, the supply trend reversed as a high rate of cash mergers and acquisitions reduced stock supply and boosted prices.
