Investment experts suggest that now might be the best time in recent market history to buy corporate bonds, primarily due to the 10-year U.S. Treasury yield hovering around 5%, which has boosted the fixed income market. Hyperscale tech companies such as Google, Amazon, Meta, and Microsoft are actively issuing bonds to fund AI projects, leveraging their strong balance sheets and manageable debt levels. The VettaFi AI Hyperscaler Bond Index yielded 6.51% at the end of September. Nevertheless, analysts caution investors to remain vigilant, as even companies with the most robust cash flows are facing pressure, exemplified by Meta's free cash flow turning negative for the first time since its 2012 IPO.
