AI Hasn't Made Stock-Picking Any Easier, Report Finds

Stock-picking has not become easier this year despite the rising use of artificial intelligence, according to a new report.

The finding lands as a rebuttal to one of the most aggressive claims in modern asset management: that machine intelligence would finally give active managers an edge over the market. It has not happened — at least not this year, the report concludes.

What does the report actually say?

The report's core claim is narrow and direct. Even with AI tools spreading through research desks and trading floors, the difficulty of picking stocks that beat the market has not declined this year.

That is a significant data point for one of the oldest debates in finance: whether skill or structure wins over time. The answer, once again, favors structure.

Why does this matter for index funds?

The report's title makes its verdict explicit: broad-market index funds remain unbeatable, even in what it calls "the era of AI stock-picking."

That phrasing matters. It does not argue that index funds won despite AI. It argues they won in an environment where AI-driven stock selection is already in wide use. The technology's arrival has not shifted the balance.

The report's own framing contains three claims worth separating:

• AI usage in investing has risen.
• Picking market-beating stocks has not become easier this year.
• Broad-market index funds remain unbeatable under these conditions.

Each claim supports the same conclusion: the case for low-cost, broad-market indexing has survived the first wave of AI enthusiasm intact.

Does AI change the active-versus-passive debate?

The report's answer is no — not yet, and not this year.

The logic behind index funds has always rested on the difficulty of persistent outperformance. If AI made that difficulty disappear, the entire argument for passive investing would weaken. The report finds the difficulty has held.

For investors, the practical takeaway is straightforward. The tool that was supposed to dethrone the index fund has not done so. The index fund keeps its place.

What should investors watch next?

The report covers this year. AI capabilities keep improving, and future reports could tell a different story. But on the evidence presented, the burden of proof still sits with anyone claiming machines can reliably beat a broad-market index — and, so far, the machines have not met it.
