Source: Shanthikumar & Yoo (2026) — “Beyond Automation: AI and the Human Value of Sell-Side Analysts”
At first this sounds like a technical finance question. Then you look closer and realise it is also a question about attention, incentives, and whether people are using information or just being impressed by it.
Every AI conversation eventually becomes a job conversation. Will it replace the poor junior person who just learned how to use Excel without crying? This paper is useful because it does not answer that question in the usual dramatic way. It does not say, “AI destroys the analyst.” It also does not say, “AI magically makes everyone brilliant.” The finding is more interesting than that. The researchers looked at investment banks that invested in AI and studied what happened to sell-side analysts. These are the people who read company filings, build forecasts, follow management, join earnings calls, and somehow turn a mountain of information into a view on a company. A lot of it is also extremely boring. The kind of work that makes you question your life choices at 11:47 p.m. After banks invested in AI, analysts produced better and more timely earnings forecasts, especially after iXBRL made filings more machine-readable. That suggests AI was not replacing the analyst’s judgment. It was speeding up the public-information processing that analysts used to do manually. The saved time did not just disappear into the calendar, although I personally would have accepted a nap.
In plain English, that is why the result matters beyond the chart. It changes where people should look, what they should question, and which comfortable assumption probably needs to be retired.
So I would not read this as a neat technology story. It is a messy information story. The tools improve, but people still have to decide what deserves attention. Annoying, but true.
