Many successful professionals in Hampton Roads choose to manage their own investments. While DIY investing can work, the data shows that individual investors consistently underperform the market—not because of poor investing, but because of behavioral mistakes. As a Norfolk-based CFP® working with affluent families across Tidewater, I see the same errors over and over again.
The good news? These mistakes are avoidable with the right structure, discipline, and planning.
Investment Problems vs. Behavior Problems
Most DIY investors don’t lack access to good investments—they struggle with behavior. Studies consistently show that individual investors trail market indices by 1–3% annually due to emotional decision-making. Over decades, that gap can cost hundreds of thousands, or even millions, of dollars in lost wealth.
Successful investing isn’t about finding the perfect stock. It’s about sticking to a disciplined plan despite emotional feelings.
1. Panic Selling During Market Declines
Market volatility is normal. The average intra-year market decline is about 14%, even in strong years. Yet many investors sell after a 15–20% drop, locking in losses and missing the rebound—which often happens quickly and without warning.
If you can’t tolerate short-term declines, your portfolio is likely misaligned with your goals and temperament.
Key takeaway: Corrections and bear markets are part of investing—not signals to abandon your plan.
2. Trying to Time the Market
Market timing requires being right twice: when to sell and when to re-enter. Even professional managers struggle to do this consistently.
There is always a “crisis of the day”—elections, interest rates, recessions, geopolitics. Waiting for uncertainty to disappear means staying out of the market indefinitely.
Key takeaway: Long-term success comes from staying invested and following your plan, not guessing headlines.
3. Chasing Last Year’s Winners
Buying what just performed well often leads to buying high and selling low. Markets rotate. What led last year may lag next year.
A properly diversified portfolio already includes exposure to areas that will outperform at different times—without needing constant tinkering.
Key takeaway: Build diversification upfront so you don’t feel compelled to chase performance later.
4. Investing Without a Written Plan
Without a written investment plan, emotions become the plan.
High-net-worth investors benefit from a clear framework that defines:
- Goals and time horizon
- Target asset allocation
- Rebalancing rules
- Expected volatility
At our firm, every client portfolio is governed by a written Investment Policy Statement (IPS). This document provides clarity during calm markets—and discipline during turbulent ones.
5. Taking the Wrong Amount of Risk
Too conservative? Your portfolio may not keep up with inflation or long-term goals.
Too aggressive? You may panic at the worst possible moment.
The right portfolio balances:
- What you need to earn
- What you’re willing to tolerate
- What you can realistically stick with during downturns
Key question: If your portfolio dropped 30%, would you stay invested—or sell?

6. Poor or Illusory Diversification
Many portfolios look diversified but aren’t. Multiple funds can hold the same underlying stocks, creating hidden concentration risk—especially in 401(k) plans with limited options.
True diversification spans:
- Asset classes
- Geographies
- Investment styles (growth vs. value)
Key takeaway: Fund names don’t equal diversification, holdings do.
7. Overconcentration in Employer Stock
Holding too much employer stock exposes you to double risk, your income and your investments depend on the same company.
We generally recommend limiting employer stock to no more than 10% of net worth and treating it as compensation—not a core investment. Systematic selling reduces risk without trying to time the stock.
8. Ignoring Fees, Taxes, and Trading Friction
Small costs compound into big losses:
- High expense ratios
- Excessive trading
- Short-term capital gains taxes
In taxable accounts, tax-efficient funds, low turnover, and disciplined trading matter just as much as investment selection.
Key takeaway: What you keep matters more than what you earn.
9. Treating Investing Like Entertainment
Day trading, options, leverage, and “hot stock tips” are speculation, not investing. Financial news networks exist to sell advertising, not to build your retirement.
Investing should be boring, systematic, and rules-based. If needed, limit speculation to a small “play money” account—never your core portfolio.
10. Ignoring Early-Retirement Sequence Risk
The first few years after retirement are the most vulnerable. A major market decline combined with portfolio withdrawals can permanently damage long-term sustainability.
Prudent retirees maintain a Plan B—cash reserves, flexible withdrawal strategies, or alternative income sources—to weather early downturns.
Final Thoughts: When DIY Investing Stops Making Sense
Successful investing requires:
- Technical knowledge
- Long-term planning
- Emotional discipline
- Tax awareness
If any of these areas feel uncertain, partnering with a fiduciary CFP® such as Wealthway Financial Advisors may significantly improve outcomes.
For those considering professional guidance, look for advisors held to a fiduciary standard through organizations like the Financial Planning Association.
