Equities shrug off oil spike, but rates and concentration risks loom, Timmer says - CNBC intervoew

Fidelity’s Jurrien Timmer says equities have largely shrugged off a recent oil spike (Brent near $100), but the S&P 500 rally remains vulnerable to two key risks: concentration in a handful of large-cap names and rising interest rates. He warns that a change in Fed leadership or policy stance—especially opposition to QE—could spark corrections, likely hitting bond markets first and then spilling into equities. For now equities have recovered quickly from the oil move, but elevated yield risks and market concentration leave the rally exposed to downside when sentiment shifts.
