(Bloomberg) -- General Electric Co.’s bonds haven’t yet found a bottom. Several of the firm’s most active securities have widened more than 30 basis points since yesterday’s close and are well over 100 basis points wider than where they traded a month ago.

GE notes maturing in 2034, issued out of the GE capital entity, rank just behind DowDuPont Inc.’s newly issued debt in total volume traded on Thursday in the investment-grade bond market. The bonds, which trade at 305 basis points above Treasuries, have widened 140 basis points since September.

The corporate credit market has been concerned about General Electric’s heavy debt load, and this has fed worry in the broader market. Guggenheim Partners Chief Investment Officer Scott Minerd tweeted on Tuesday that the company’s problems aren’t isolated, and “the slide and collapse in investment grade credit has begun.” Those concerns were echoed by Jason Shoup, head of global credit strategy at Legal & General Investment Management America.
