“Your journey through retirement is like a road trip with many twists and turns. Thoughtful diversification is an important tool for navigating this ride, helping to smooth out the bumps that could otherwise slow you down or derail your progress. Market volatility is part of the trip. While speeding ahead can lead to higher returns over time, the volatility along the way can be unsettling during market downturns, making it hard to stay the course.

By spreading your investments across different lanes—some focused on income, others on growth—you can build a portfolio that adapts to changing conditions and keeps you on track toward your goals. This strategy allows you to patiently ride out market turbulence and take advantage of opportunities to rebalance.

The classic ‘buy low, sell high’ mantra can be difficult without diversification, but by investing in different assets that move at different speeds, you can rebalance during those market traffic jams. Think of it like driving: When one lane stops and another starts moving, it’s tempting to switch lanes. But we all know what happens next—as soon as you switch, your new lane grinds to a halt, and the old one zooms by.

This is a reminder to resist the urge to jump in and out of markets, trying to time them perfectly—a nearly impossible task.

It’s hard not to follow the crowd when the investments we’re holding aren’t performing as expected. But if they’re still quality investments that have temporarily dropped in price, that’s the time to buy more, not less. Rebalancing allows you to do just that.

On the flip side, it can be difficult to sell investments that have outperformed, but it’s important to zoom out, see the bigger picture, and stick to the plan you’ve mapped out.

The goal is balance—not being too aggressive or too cautious.

By setting guardrails and regularly monitoring each lane’s performance, you can optimize your portfolio. For instance, you might set a rule to move 5 percent from cash or fixed income into growth assets if the stock market drops by 10 percent or more. You can also create similar rules for when your cash reserves or income lanes start to fall behind.

This helps you stay disciplined and avoid emotional reactions to big market swings, which can feel very different when you’re dealing with two-comma wealth. After all, the percentage returns may stay the same, but six-figure portfolio fluctuations can hit differently than they did before.

Whether you’re cruising in the steady income lane or enjoying the thrill of the growth lane, each has its purpose. Finding the right balance between risk and stability is the key to managing your two-comma wealth.

As Bob’s experience showed us, it’s not just about how much you have—it’s about how you manage it across these lanes. Strategies like the bucket system and proper diversification can give you the confidence to handle whatever road you choose.”

“Concentrating your assets may have helped build your wealth, but diversifying is essential for making it last during retirement.

ACTION STEP:

Reflect on whether your current diversification strategy supports your goals for maintaining financial stability.

EXAMPLE:

Jay transitioned from a portfolio of tech stocks to a diversified mix of asset classes and sectors, ensuring his wealth could weather market volatility and sustain his retirement income.

How does your current diversification strategy help you balance preservation and growth? Are there areas where you might adjust to better meet your financial goals?”
