20 Investment Mistakes to Avoid
From emotionally-driven investment decisions to paying too much on fees, here are some of the most common investing mistakes:
Top 20 Mistakes | Description |
---|---|
1. Expecting Too Much | Having reasonable return expectations helps investors keep a long-term view without reacting emotionally. |
2. No Investment Goals | Often investors focus on short-term returns or the latest investment craze instead of their long-term investment goals. |
3. Not Diversifying | Diversifying prevents a single stock from drastically impacting the value of your portfolio. |
4. Focusing on the Short Term | It’s easy to focus on the short term, but this can make investors second-guess their original strategy and make careless decisions. |
5. Buying High and Selling Low | Investor behavior during market swings often hinders overall performance. |
6. Trading Too Much | One study shows that the most active traders underperformed the U.S. stock market by 6.5% on average annually. Source: The Journal of Finance |
7. Paying Too Much in Fees | Fees can meaningfully impact your overall investment performance, especially over the long run. |
8. Focusing Too Much on Taxes | While tax-loss harvesting can boost returns, making a decision solely based on its tax consequences may not always be merited. |
9. Not Reviewing Investments Regularly | Review your portfolio quarterly or annually to make sure you’re staying on track or if your portfolio is in need of rebalancing. |
10. Misunderstanding Risk | Too much risk can take you out of your comfort zone, but too little risk may result in lower returns that do not reach your financial goals. Recognize the right balance for your personal situation. |
11. Not Knowing Your Performance | Often, investors don’t actually know the performance of their investments. Review your returns to track if you are meeting your investment goals factoring in fees and inflation. |
12. Reacting to the Media | Negative news in the short-term can trigger fear, but remember to focus on the long run. |
13. Forgetting About Inflation | Historically, inflation has averaged 4% annually. Value of $100 at 4% Annual Inflation After 1 Year: $96 After 20 Years: $44 |
14. Trying to Time the Market | Market timing is extremely hard. Staying in the market can generate much higher returns versus trying to time the market perfectly. |
15. Not Doing Due Diligence | Check the credentials of your advisor through sites like BrokerCheck, which shows their employment history and complaints. |
16. Working With the Wrong Advisor | Taking the time to find the right advisor is worth it. Vet your advisor carefully to ensure your goals are aligned. |
17. Investing With Emotions | Although it can be challenging, remember to stay rational during market fluctuations. |
18. Chasing Yield | High-yielding investments often carry the highest risk. Carefully assess your risk profile before investing in these types of assets. |
19. Neglecting to Start | Consider two people investing $200 monthly assuming a 7% annual rate of return until the age of 65. If one person started at age 25, their end portfolio would be $520K, if the other started at 35 it would total about $245K. |
20. Not Controlling What You Can | While no one can predict the market, investors can control small contributions over time, which can have powerful outcomes. |
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 common investing 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.

An Investor’s Guide to Copper
Copper is the world’s third-most utilized industrial metal and the linchpin of many clean energy technologies. It forms the vital connections in our electricity networks, grid storage systems, and electric vehicles.
In this graphic, sponsored by iShares, we dig into the forces that are set to shape the future of the copper landscape.
How Much Copper Do We Need?
Copper is poised to experience a remarkable 54% surge in demand from 2022 to 2050.
Here’s a breakdown of the expected demand for copper across clean energy technologies.
Technology | 2022 (kt) | 2050P (kt) |
---|---|---|
Electricity networks | 4364 | 8862 |
Other low emissions power generation | 93.7 | 142.2 |
Solar PV | 756.8 | 1879.8 |
Grid battery storage | 24.6 | 665.2 |
Wind | 453.5 | 1303.3 |
Hydrogen technologies | - | 0.22 |
Electric vehicles | 370 | 3582.9 |
Other uses | 19766 | 22382 |
Copper is vital in renewable energy systems such as wind turbines, solar panels, and electric vehicle batteries because of its high electrical conductivity and durability.
It ensures the effective transmission of electricity and heat, enhancing the overall performance and sustainability of these technologies.
The rising demand for copper in the clean energy sector underscores its critical role in the transition to a greener and more sustainable future.
When Will Copper Demand Exceed Supply?
The burgeoning demand for copper has set the stage for looming supply challenges with a 22% gap predicted by 2031.
Given this metal’s pivotal role in clean energy and technological advancements, innovative mining and processing technologies could hold the key to boosting copper production and meeting the needs of a net-zero future.
Investing in Copper for a Prosperous Future
Investors looking for copper exposure may want to consider an ETF that tracks an index that offers access to companies focused on the exploration and mining of copper.
