Companies have been rushing to issue bonds as yields spiked to touch new highs with the Federal Reserve looking to keep interest rates higher for longer.
The average yield on U.S. investment grade bonds rose to 5.55% on Monday from just 4.94% on Feb. 1.
"There's much more yield now to be had in corporates," said David del Vecchio, co-head of the U.S. investment grade corporate bond team at PGIM Fixed Income.
Investors still had plenty of cash, despite the flurry of issuance, said Blair Shwedo, head of IG corporate bond trading at U.S. Bank.
"With more volatility, you may see some short term negative returns but overall, we’re well positioned to have a very nice positive total return in investment grade credit in 2023," said Natalie Trevithick, head of investment grade credit strategy at investment management firm Payden & Rygel.
