Shares of banks and other financial institutions ticked down as concerns about private credit offset optimism about mortgage and commercial lending.

Shares of private-credit firms Blue Owl, Blackstone, Ares Management and Apollo Global all fell by 4.9% or more.

"Sunshine and time heals all wounds," said Oliver Pursche, senior vice president at financial advisory Wealthspire. "The fact that there's a focus on and an awareness of the issues with private credit...[and] on the lower lending standards that were applied in the boom years is a big positive. This can correct itself over time."

Credit investors are generally prepared for some level of default as long as risks are transparent, Pursche said.
