On Schwab Network Molly Pieroni argued that Samsung sits at the epicenter of artificial intelligence (AI) memory's surge in demand while also running a healthy foundry business, and she flagged Berkshire Hathaway (BRK/B) as a low-valuation, shareholder-friendly defensive pick.

For anyone worried about concentration in AI winners, the segment is a tidy reminder to balance growth bets with durable, cash-generating ballast.
