Common First-Investor Mistakes To Skip

Most first-time investor mistakes fall into predictable patterns. Knowing them ahead of time saves years of learning by expensive experience.



The first common mistake is trying to pick individual stocks before understanding index funds. Individual stocks require research, ongoing monitoring, and a strong stomach. Index funds require none of these and outperform most active stock pickers over decades.



The second common mistake is buying investment products from someone whose income depends on selling them. Whole life insurance sold as an investment, high-fee variable annuities, and load mutual funds are the classic examples. If someone earns a commission on selling you the product, expect the product to cost you more.



The third common mistake is checking the portfolio too often. Frequent checking creates emotional reactions to normal volatility. Once a quarter is plenty for most long-term investors.



The fourth common mistake is stopping contributions during a downturn. This locks in losses and skips the moments when future returns are highest. Automation prevents this.



The fifth common mistake is spreading contributions across too many accounts and funds. Simplicity almost always wins over the long term.

The compounding cost of avoiding one or two of these mistakes over a career is often larger than any active investment decision you will make.
