Fresh US economic data painted a mixed picture of late-summer momentum. On one hand, factory activity cooled in August and construction spending slipped in July. On the other, the Atlanta Fed's GDPNow model—a real-time tracker of economic growth—lifted its estimate for third-quarter GDP to a robust 4.8% annualized rate.
For everyday investors, the takeaway is that the economy isn't moving in one clear direction. Instead, it's sending conflicting signals that could influence everything from stock market sentiment to interest rate expectations.
What the data shows
The Institute for Supply Management (ISM), an industry group, reported that its manufacturing index eased to 54.6 in August from 55.6 in July. A reading above 50 still indicates expansion, so the sector remains in growth territory—but the pace has slowed. New orders, production, and employment all softened, suggesting that manufacturers are seeing less demand than earlier in the summer.
Encouragingly, the prices-paid component held steady, which could mean that slower activity isn't accompanied by fresh inflationary pressure. That's a relief for investors worried about the Federal Reserve having to keep interest rates higher for longer.
Separately, the Commerce Department said construction spending fell in July, a decline that adds to the cooling picture. Construction is often sensitive to interest rates, so the drop could reflect the impact of elevated borrowing costs on both residential and commercial projects.
The GDPNow counterpoint
Yet the Atlanta Fed's GDPNow model—a widely watched estimate that updates frequently as new data arrives—now projects 4.8% annualized growth for the third quarter. That's a strong number, well above the roughly 2% pace that many economists consider the US economy's long-run potential.
How can factory activity cool and construction fall while GDP growth accelerates? The answer lies in what GDPNow tracks. The model incorporates a broad range of data, including consumer spending, trade, and inventories. It's possible that strength in other areas—like services or net exports—is offsetting the manufacturing softness. Also, GDP measures total output, and construction spending is just one slice of that pie.
It's also worth noting that GDPNow is a model, not a forecast. It can swing sharply from week to week as new data rolls in. A 4.8% reading is eye-catching, but it's not a guarantee of what the official GDP report will show.
What it means for investors
For investors, the mixed signals create a tricky environment. On one hand, strong GDP growth suggests corporate earnings could remain resilient, which is supportive for stocks. On the other, cooling factory activity and falling construction spending hint at a slowdown that could weigh on specific sectors, like industrials, materials, and homebuilders.
The steady prices-paid reading is a key detail. If inflation stays contained, the Federal Reserve may feel less pressure to hike rates further. That could be positive for bonds and for growth stocks, which tend to be sensitive to interest rate expectations. However, if growth remains strong, the Fed might keep rates higher for longer to prevent the economy from overheating.
Investors should also watch how these trends evolve. The ISM index is just one month's reading, and construction spending can be volatile. A single data point doesn't make a trend. But when multiple indicators diverge, it's a reminder that the economy is complex and that forecasts can be wrong.
For those with diversified portfolios, the key is to avoid overreacting to any single report. The stock market often moves on surprises, and the mixed data could lead to choppy trading in the near term. Long-term investors might focus on the broader picture: the US economy is still growing, inflation is cooling, and the labor market remains resilient—even if the pace is uneven.
As always, it's wise to keep an eye on upcoming data releases, including the next jobs report and inflation readings, which will provide more clarity on the economy's trajectory. For now, the mixed signals are a reminder that the path forward is rarely a straight line.
