Valuations vs. the Dot‑Com Era

A shift in mindset can help investors cope with market uncertainty.

2025 was a case study in the futility of trying to predict the market. Wall Street had lofty expectations for stocks entering the year. Then the tariff shock in April rattled the markets and many firms lowered their annual stock forecasts in response. They later raised them—after stock prices rebounded. With the new year on the horizon, Morningstar’s 2026 Global Outlook report is offering investors tactics to weather whatever the future may hold.

Morningstar strategists and an analyst will discuss key challenges facing investors in 2026 in our series. Dan Kemp, the chief research and investment officer with Morningstar Investment Management Europe, is one of the major driving forces behind the report.

We’re going to dig into research analyzing the AI arms race and its worldwide buildout. A team of Morningstar researchers have investigated the spending and the risks. Morningstar Research Services’ senior equity analyst Brian Colello was part of the effort. Brian also covers Nvidia. He discusses the AI king’s outlook, competition, and stock.
