Why is my 401(k) rising? More Fed rate cuts on the way? We answer your economy questions

The stock market has appeared to follow a crude pattern in recent months.

It looks something like this: See the Fed predict more interest rate cuts than expected.

See the market soar.

The dynamic held to form last week when the Federal Reserve stuck to its forecast of three rate cuts this year despite a worrisome inflation pickup in January and February. The S&P 500 index has jumped 1.1% since the Fed’s announcement midday Wednesday and closed at 5,234 Friday, just off the previous day's record high.

But there’s a bit more nuance to what looks like a knee-jerk response to the financial rocket fuel of low interest rates, analysts say. The outlook for the U.S. economy and corporate earnings has brightened considerably in the past few months. Investors like that narrative even more than they like low interest rates.

“I think the market is focused more on earnings and the economy than the Fed,” says Chris Zaccarelli, chief investment officer of Independent Advisor Alliance.

And that means the market's rally since autumn could have legs, a development that would further lift Americans’ 401(k) balances and other investments this year even after an already big run-up.

“I think it’s got more room to run,” Zaccarelli says.

Why is the stock market going up?

There’s little doubt the Fed’s median estimate Wednesday of three rate cuts in 2024 propelled stocks higher last week. After the inflation flare-up early this year, many economists figured officials would scale back their forecast to two cuts to ensure consumer price increases are subdued before lowering rates sharply. Fed Chair Jerome Powell suggested the price spike could be a blip and officials will monitor the data closely in the coming months.

But Fed officials last week also predicted the economy will grow 2.1% this year, down from a robust 3.1% in 2023 but well above their 1.4% forecast in December. Consumer spending and job growth have been surprisingly resilient despite high borrowing costs and prices, largely as a result of healthy pay increases. The Fed's more bullish view also drove up stock values, Zaccarelli says.

What is the corporate earnings forecast for 2024?

Meanwhile, earnings of S&P 500 companies are projected to grow 10.9% in 2024, according to FactSet. That’s up from low single-digit increases last year, a leap that can partly be traced to the resolution of pandemic-related supply chain snarls and faster growth in productivity, or output per worker, says Ryan Detrick, chief market strategist of Carson Group, an investment firm.

On the surface, it may look as if the stock market is all about the Fed and interest rates. Wall Street likes lower borrowing costs for consumers and businesses because they spur faster growth, which should boost corporate profits. Lower rates also coax investors to move money from bonds that now have lower returns to higher-yielding stocks.
