15 Common Investment Mistakes and How to Avoid Them

Investing can be an excellent way to grow your wealth and secure your financial future, but it can also be risky if you don’t know what you’re doing. Common investment mistakes can lead to significant financial losses, so it’s important to be aware of these mistakes and know how to avoid them.

Mistake #1: Not Having a Plan

One of the biggest mistakes investors make is not having a plan. Without a plan, you are likely to make impulsive decisions that may not be in your best interest. A good investment plan should include your financial goals, risk tolerance, and a strategy for reaching those goals.

Avoidance Tip: Take the time to develop a comprehensive investment plan that aligns with your financial goals and risk tolerance. Consult a financial advisor if necessary to ensure your plan is sound.

Mistake #2: Chasing High Returns

Investors often fall into the trap of chasing high returns without considering the potential risks. High-return investments can be tempting, but they often come with a higher risk of losing your money.

Avoidance Tip: Focus on investing in a well-diversified portfolio of low-cost index funds and exchange-traded funds (ETFs) rather than trying to find the next big stock that will make you rich overnight.

Mistake #3: Timing the Market

Many investors try to time the market, thinking they can buy low and sell high. However, timing the market is nearly impossible and can lead to significant losses if you’re wrong.

Avoidance Tip: Instead of trying to time the market, adopt a long-term investment strategy and stick to it. Invest in a well-diversified portfolio and hold onto your investments, even during periods of market volatility.

Mistake #4: Not Understanding the Investment

Before investing in anything, it’s important to understand what you’re investing in. This means researching the investment, the company behind it, and the risks involved.

Avoidance Tip: Take the time to research any investment before you buy. Read the prospectus, consult a financial advisor, and educate yourself on the investment and the company behind it.

Mistake #5: Not Diversifying Your Portfolio

Having a diversified portfolio is essential to reducing your investment risk. If you invest all your money in one stock or one sector, you’re putting all your eggs in one basket and leaving yourself exposed to significant financial losses if that stock or sector performs poorly.

Avoidance Tip: Diversify your portfolio by investing in a mix of stocks, bonds, real estate, and other assets. Spread your investments across different sectors and geographies to reduce your risk.

Mistake #6: Not Monitoring Your Investments

Many investors make the mistake of investing their money and then forgetting about it. This can lead to missed opportunities or even financial losses if the investment performs poorly.

Avoidance Tip: Regularly review your investments and make adjustments as needed. Stay up-to-date on market news and economic trends, and be prepared to make changes if the investment is no longer aligned with your financial goals.

Mistake #7: Following the Crowd

Investors often follow the crowd and invest in what’s popular without considering whether it’s a good fit for their financial goals and risk tolerance. This can lead to poor investment decisions and significant financial losses.

Avoidance Tip: Do your own research and make investment decisions based on your own financial goals and risk tolerance, not what everyone else is doing.

Mistake #8: Not Keeping Emotions in Check

Emotions can play a significant role in investment decisions. Fear and greed are two emotions that can lead to poor investment decisions. Fear can cause you to sell your investments too early, while greed can cause you to hold onto losing investments for too long.

Avoidance Tip: Stay focused on your investment plan and avoid letting your emotions dictate your investment decisions. If you’re feeling particularly emotional, take a step back and reconsider your investment decisions.

Mistake #9: Not Considering Taxes

Investors often overlook the impact of taxes on their investment returns. Taxes can eat into your investment returns, reducing your overall wealth.

Avoidance Tip: Consider the tax implications of your investments and choose investments that are tax-efficient. For example, consider investing in tax-deferred retirement accounts, such as a traditional IRA or a 401(k).

Mistake #10: Ignoring Inflation

Inflation is the gradual increase in the cost of goods and services over time, and it can erode the value of your investments if you don’t take it into account.

Avoidance Tip: Consider the impact of inflation on your investments and choose investments that offer a higher return than the rate of inflation. For example, stocks and bonds typically offer a higher return than savings accounts, which may be more affected by inflation.

Mistake #11: Not Being Realistic

Investors often have unrealistic expectations about the returns they can expect from their investments. High returns are possible, but they are also accompanied by high risk.

Avoidance Tip: Be realistic about the returns you can expect from your investments and choose investments that align with your financial goals and risk tolerance. Don’t chase high returns without considering the potential risks.

Mistake #12: Not Keeping Investment Costs Low

Investment costs can eat into your returns, reducing your overall wealth. High fees, commissions, and other costs can significantly reduce your returns over time.

Avoidance Tip: Choose low-cost investment options, such as index funds and exchange-traded funds (ETFs), to keep investment costs low. Consider working with a fee-only financial advisor who can help you choose low-cost investment options that are right for you.

Mistake #13: Not Having a Long-Term Perspective

Many investors focus on short-term results and sell their investments too quickly, missing out on the long-term growth potential of their investments.

Avoidance Tip: Have a long-term perspective when investing. Focus on your financial goals and invest in a diversified portfolio that aligns with your risk tolerance and time horizon. Avoid making impulsive decisions based on short-term market fluctuations.

Mistake #14: Not Sticking to a Plan

Investors often deviate from their investment plan, making impulsive decisions based on market conditions or news events. This can lead to inconsistent returns and missed opportunities.

Avoidance Tip: Stick to your investment plan and avoid making impulsive decisions. If you feel the urge to make a change, take the time to re-evaluate your investment plan and make any necessary adjustments in a thoughtful and strategic manner.

Mistake #15: Not Seeking Professional Help

Some investors try to manage their investments on their own, without seeking professional help. This can lead to mistakes and missed opportunities.

Avoidance Tip: Consider working with a financial advisor who can help you create and implement an investment plan that aligns with your financial goals and risk tolerance. Financial advisors can also help you avoid common investment mistakes and provide valuable insights and guidance.


Investing can be a complex and challenging task, but by avoiding common investment mistakes, you can increase your chances of success. By having a long-term perspective, sticking to a plan, seeking professional help, and avoiding the mistakes outlined above, you can make smart investment decisions that help you reach your financial goals.
