The 20 Most Common Investment Mistakes

No one is immune to errors, including the best investors in the world.

Fortunately, investment mistakes can provide valuable lessons over time, providing investors an opportunity to gain insights on investing—and build more resilient portfolios.

This graphic shows the top 20 mistakes to watch out for, according to the CFA Institute.

20 Investment Mistakes to Avoid

From emotionally driven investment decisions to paying too much on fees, here are some mistakes that investors commonly make:

For instance, not properly diversifying can expose you to higher risk. Holding one concentrated position can drastically impact the value of your portfolio when prices fluctuate.

In fact, one study shows that the optimal diversification for a large-cap portfolio is holding 15 stocks. In this way, it helps capture the highest possible return relative to risk. When it came to a small-cap portfolio, the number of stocks rose to 26 for optimal risk reduction.

It’s worth noting that one size does not fit all, and seeking financial advice can help you find the right balance based on your financial goals.

Another common mistake is trading too much. Since each trade can rake up fees, this can impact your overall portfolio performance. A separate study showed that the most active traders saw the worst returns, underperforming the U.S. stock market by 6.5% on average annually.

Finally, it’s important to carefully monitor your investments regularly as market conditions change, factoring in fees and inflation. This will let you know if your investments are on track, or if you need to adjust based on changing personal circumstances or other factors.

Controlling What You Can

To help avoid these mistakes, investors can remember to stay rational and focus on their long-term goals. Building a solid portfolio often involves assessing the following factors:

• Financial goals
• Current income
• Spending habits
• Market environment
• Expected returns

With these factors in mind, investors can avoid focusing on short-term market swings, and control what they can. Making small investments over the long run can have powerful effects, with the potential to accumulate significant wealth simply by investing consistently over time.

A Visual Guide to Economic Indicators

Economic indicators provide insight on the state of financial markets.

Each type of indicator offers data and economic measurements, helping us better understand their relationship to the business cycle. As investors navigate the market environment, it’s important to differentiate between the three main types of indicators:

• Leading
• Coincident
• Lagging

The above infographic from New York Life Investments shows a road map of indicators and what they can tell us about the economy.

What’s Ahead: Leading Indicators

Leading indicators present economic data that point to the future direction of the economy like a sign up ahead. Here are three examples.

1. Consumer Confidence Index

This key measure indicates consumer spending and saving plans. When the index is above 100, consumers may spend more over the next year. In December, the index jumped to 108 up from 101 in November. This was in part due to lower inflation expectations and improving job prospects.

In the December survey, 48% indicated that the job market remained strong, highlighting the strength of employment opportunities and likely influencing sentiment towards spending in the future.

2. ISM Purchasing Managers Index

The ISM Purchasing Managers Index indicates expectations of new orders, costs, employment, and U.S. economic activity in the manufacturing sector. The following table shows how the index is broken down based on select measures:

For instance, in November the index fell into its first month of contraction since May 2020. Falling new orders signal that demand has weakened while contracting employment figures indicate lower output across the sector.

3. S&P 500 Index

The S&P 500 Index indicates the economy’s direction since forward-looking performance is factored into prices. In this way, the S&P 500 Index can represent investor confidence as the index often serves as a proxy for U.S. equity markets. In 2022, returns for the index are roughly -20% year-to-date.

Current Conditions: Coincident Indicators

Coincident indicators reflect the current state of the economy, showing whether it is in a state of growth or contraction.

1. GDP

GDP indicates overall economic performance. Typically it serves as the most comprehensive gauge of the economy since it tracks output across all sectors. In the third quarter of 2022, real U.S. GDP increased 2.9% on an annual basis. That compares to 2.7% for the same period in 2021.

2. Personal Income

Rising incomes indicate a healthier economy and falling incomes signal slower growth. Personal income grew at record levels in 2021 to 7.4% annually amid a rapid economic expansion.

This year, U.S. personal income has grown at a slower pace, at 2.7% on an annual basis as of the third quarter.

3. Industrial Production Index

Strongly correlated to GDP, the industrial production index indicates manufacturing, utilities, and mining output. Below, we show trends in industrial production and how they correspond with GDP and personal income indicators.

*As of Q3 2022.

As the above table shows, factory production collapsed following the 2008 financial crisis, a key indicator for the depth of an economic downturn. Meanwhile, personal income sank over -3% while GDP fell -2%.

Despite economic uncertainty in 2022, industrial production remains positive, at a 4.7% growth rate, albeit somewhat slower than 2021 levels.

Rearview Mirror: Lagging Indicators

Like checking your back mirror, lagging indicators take place after a key economic event, often confirming what has taken place in the economy. Here are three key examples.

1. Interest Rates

Often, interest rates respond to changes in inflation. When rates rise it can slow economic growth and discourage borrowing. Rising interest rates typically signal a strong economy and are used to tame inflation. On the other hand, low interest rates promote economic growth.

Following years of record-low interest rates, the Federal Funds rate increased at the fastest rate in decades over 2022, jumping from 0.25% in March to 4.25% in December as inflation accelerated.

2. Consumer Price Index

This inflation measure can indicate cash flow for households. Inflation is often the result of rising input costs and increasing money supply across the economy.

Sometimes, inflation can reach a peak after an expansion has ended as rising demand in an economy has pushed up prices. In November, U.S. inflation reached 7.1% annually amid supply chain disruptions and price pressures across food prices, medical prices, and housing costs.

*As of November 2022.

3. Unemployment Rate

The unemployment rate has many spillover effects, impacting consumer spending and in turn retail sales and GDP. Historically, unemployment falls slowly after an economic recovery which is why it’s considered a lagging indicator. When the unemployment rate rises it confirms lagging economic performance.

Overall, 2022 has been characterized by a strong job market, with unemployment levels below historical averages, at 3.7% as of October.

On the Road

To get a more comprehensive picture of the economy, combining a number of indicators is more effective than isolating a few variables. With these tools, investors can gain more perspective on the cyclical nature of the business cycle while keeping a long-term perspective in mind on the road ahead.
