Wall Street's appetite for artificial-intelligence stocks is back in force. According to the Los Angeles Times, stocks rose as investors showed they are "still hungry for AI winners," extending a rally that has defined much of the year.

The gains have not been evenly spread. The Globe and Mail reports that three stocks "crushed Nvidia" with gains of 300% or more over the past year — a reminder that even the AI poster child has been outrun by lesser-known names. CNBC describes chip stocks as having "a wild but strong week," with Meta leading its featured portfolio higher, even as volatile oil prices kept Wall Street on edge.

Not everyone is chasing the same trades. CNBC reports that ETF Action's Mike Akins is encouraging investors to add exposure to groups that have underperformed the biggest AI names, betting those laggards could deliver bigger returns over the next six months.

There are cautionary voices too. Yahoo Finance reports that Morgan Stanley has flagged a "$1.2 trillion question" hanging over the rally, as investors lean on resilient earnings and AI spending heading into the second half. And Yahoo! Finance Canada highlights a portfolio manager warning that "most companies are essentially failing" to profit from AI, cautioning that the divide could hurt Canadian portfolios. Separately, Yahoo Finance notes one manager explaining why Microsoft is not their top pick.

Why it matters: AI stocks now anchor major indexes, so how long Wall Street's enthusiasm holds — and whether the gains broaden or stay concentrated — will shape the retirement and investment accounts of ordinary people, not just tech insiders.
