Every two weeks, millions of paychecks buy stocks. Nobody checks the news first. The money comes out of the check and goes into a 401(k) or an IRA. Spencer Jakab's Heard on the Street column asks what happens to that flow if AI takes the jobs those paychecks come from.
Duncan Lamont runs strategic research at Schroders. His report came out in late October. His point is that we watch short-term market signals too much and the paycheck flow too little. In recent years, close to half a trillion dollars a year has moved from workplace plans and IRAs into U.S. stocks alone. By his count, for every other dollar that bought U.S. stocks, company buybacks included, retirement accounts put in 30 to 78 cents. "These contributions don't care about valuations," he says. They don't care about headlines either.
Who does the buying
Here's the catch. The people who contribute the most are the ones AI could hit first. About 87% of finance workers and 80% of tech workers are in a workplace plan. They also have the highest pay and the biggest company matches. Only 14% of leisure and hospitality workers contribute to a 401(k), and they earn much less. Schroders' AI-boom scenario has unemployment reaching 10% by 2030. That's a scenario, and nobody should read it as a forecast. Even a milder job shock would land on the biggest savers.
There's been no wave of AI layoffs so far. Hiring is a different story. Companies have hired far fewer young white-collar workers, such as software developers, since ChatGPT launched. A chart with the column shows employment for developers aged 22 to 25 down about a fifth since late 2022, by our read of it. Those young workers put more of each contribution into stocks than people near retirement do. Lamont's worry is simple. A small change in buying at the margin can move prices a lot. Price-sensitive buyers may balk at money-losing AI companies valued in the trillions.
Our read
This is a Retirement story, M10 in our planning map, with a Career edge. The automatic contribution is the steadiest buyer in the market and the steadiest builder in your plan. It kept buying through 2022, and it bought on Thursday, Nov. 5, when the Nasdaq fell 5.5%. We'd keep it running. The one thing that stops it is a lost job. So the job-loss plan is part of the retirement plan. For a young worker in software or finance, it's the most important part right now.
Here's your check this week. Open the 401(k) app and confirm two things. Your contribution is still on, and you're getting the full company match. Then look at the other account, the one that keeps the contribution alive. If you work in a field where hiring has slowed, count how many months of bills your emergency fund covers. That fund is what lets the 401(k) keep buying between jobs. You check the spare tire before the trip. On the shoulder is too late. If you want help sizing that fund to your own bills, bring it to a planning review.
