The economy continues to show surprising strength. Businesses are investing, corporate profits have been growing, and consumer spending remains resilient.
So why should investors be concerned?
Because a strong economy doesn’t necessarily translate into strong future investment returns.
In fact, some of the same forces supporting economic growth today may also be creating additional risks for investors.
I recently read an insightful third-quarter economic and market outlook from Larry Swedroe, an investment author and researcher whose work focuses on evidence-based investing. His commentary highlighted several important developments involving interest rates, government debt, and investment diversification.
Here are five takeaways that I believe are particularly relevant for investors approaching or living in retirement.
1. The Economy Is Stronger Than Many Expected
Despite persistent concerns about inflation and interest rates, the economy has continued to expand.
Businesses are investing heavily in technology and artificial intelligence, and consumer spending has remained relatively strong. Professional economic forecasters have also become somewhat more optimistic about near-term growth.
These are encouraging developments.
However, it’s important to distinguish between the economy and the stock market.
Stock prices reflect not just current economic conditions, but also investors’ expectations about the future.
A strong economy can support corporate profits, but that doesn’t necessarily mean stocks are attractively priced.
The takeaway: Economic growth is encouraging, but it shouldn’t be the sole basis for our investment decisions.
2. Higher Interest Rates Have Changed the Investment Landscape
For much of the past 15 years, investors faced an unusual environment: Interest rates were extremely low, and bonds offered relatively little income.
That has changed.
Higher interest rates have made bonds more attractive, creating opportunities to earn meaningful income without relying entirely on stocks.
But there’s another side to this development.
When relatively safe investments offer higher returns, investors may be less willing to pay premium prices for stocks.
Think of it this way: If an investor can earn an attractive return from a high-quality bond, they may demand a higher expected return before accepting the additional uncertainty of stocks.
That can put pressure on stock market valuations.
The takeaway: Higher interest rates create both opportunities and risks. Bonds offer more attractive yields, while stocks face greater competition for investors’ capital.
3. Government Debt Is a Risk Worth Watching
One of the more concerning issues highlighted in Swedroe’s commentary is the continued growth in federal government debt.
The federal government is running substantial budget deficits even though the economy remains relatively strong.
As government debt increases, so does the cost of servicing that debt.
Over time, investors may demand higher interest rates to compensate for concerns about inflation, borrowing needs, and the government’s fiscal outlook.
Why does this matter to investors?
Because higher long-term interest rates can create challenges for both stocks and bonds.
They can reduce the market value of existing bonds and make future corporate earnings less valuable in today’s dollars.
There’s also a potentially important consequence for diversification.
Historically, long-term government bonds have often performed well during recessions, helping offset stock market declines.
But if concerns about inflation and government borrowing keep interest rates elevated, that protection may be less reliable in certain economic environments.
This doesn’t mean government bonds have lost their value. It means we shouldn’t assume they’ll always behave exactly as they have in the past.
The takeaway: Diversification remains important, but we also need to understand the risks within the investments we’re using.
4. Stock Market Valuations Matter
One distinction I often discuss with clients is the difference between a good company and a good investment.
A business can be highly successful, increase its profits, and have an excellent future.
But if investors pay too much for those future profits, their investment returns may still be disappointing.
Stock market valuations are elevated, reflecting considerable optimism about future growth and profitability.
That optimism may prove justified.
However, higher starting valuations generally translate into lower expected future returns, all else being equal.
This doesn’t mean a market correction is imminent. Markets can remain expensive for a long time.
It simply means we should be thoughtful about the amount of risk we’re taking relative to the returns we can reasonably expect.
The takeaway: Rather than trying to predict the next market decline, we want to ensure that our investment strategy reflects both the opportunities and risks that exist today.
5. Diversification Is About Preparing for Different Outcomes
Perhaps the most important message from Swedroe’s commentary is the need to build portfolios that don’t depend too heavily on a single economic outcome.
Stocks generally benefit from economic growth and rising corporate profits.
High-quality bonds can provide income and stability, although they remain sensitive to changes in interest rates.
But what happens if inflation remains elevated, interest rates rise, or stocks and bonds decline together?
This is where additional forms of diversification may be helpful.
Depending on the investor’s circumstances, we may consider investments such as:
- Inflation-protected bonds (TIPS): Designed to help preserve purchasing power by adjusting their principal value with changes in inflation. When held to maturity, individual TIPS provide a return above inflation based on the real yield at purchase, assuming the U.S. government meets its obligations.
- Gold: May provide diversification during periods of financial instability, geopolitical uncertainty, or declining confidence in currencies. While gold has historically preserved purchasing power over very long periods, it is not a reliable short-term inflation hedge and doesn’t consistently rise during market downturns.
- Commodities: May help diversify a portfolio during certain inflationary environments, particularly when rising prices are driven by increases in energy or raw material costs.
- Alternative investment strategies: Approaches such as trend following that seek returns from sources other than traditional stock and bond markets. These strategies may behave differently during sustained market trends or periods of significant volatility.
None of these investments is a perfect solution. Each introduces its own risks, costs, and trade-offs.
For example, gold produces no income and can experience significant price fluctuations. TIPS can decline in market value when real interest rates rise, particularly if sold before maturity. Alternative strategies can experience extended periods of disappointing returns.
The objective isn’t to own as many different investments as possible.
It’s to combine investments that respond differently to changing economic conditions.
The takeaway: A well-diversified portfolio should be built to handle more than one possible economic scenario.
What Does This Mean for Your Retirement Plan?
When you’re approaching or living in retirement, market conditions take on additional importance.
You’re no longer investing solely to accumulate wealth. You’re also thinking about how to turn that wealth into a dependable source of retirement income.
That introduces considerations beyond simply maximizing investment returns.
We need to think about how much investment risk is appropriate, how withdrawals will be funded during market declines, and how to protect purchasing power over what could be a 25- or 30-year retirement.
My approach centers on three principles:
- Take the right amount of risk. Your portfolio should reflect your goals, financial circumstances, and ability to withstand market declines—not simply your expectations about where the market is headed.
- Diversify across different sources of return. We want a portfolio that has the potential to perform reasonably well under a variety of economic conditions, rather than one that depends on a specific forecast being correct.
- Connect your investment strategy to your retirement income plan. The timing and flexibility of withdrawals, cash reserves, and reliable income sources can be just as important as investment performance.
The Bottom Line
There are legitimate reasons to be optimistic about the economy. There are also meaningful risks involving interest rates, government debt, and stock market valuations.
Both can be true at the same time.
We don’t know precisely how these competing forces will unfold, and we don’t need to pretend that we do.
Instead, the goal is to construct a thoughtful investment strategy that can adapt to changing conditions while remaining focused on what matters most: your long-term financial goals.
Successful retirement investing isn’t about predicting every market turn.
It’s about building a plan that doesn’t require us to be right about what happens next.
