More Chinese technology companies might turn to convertible bonds after Alibaba Group Holding Ltd. and JD.com Inc. raised a combined $6.5 billion through such notes, said UBS, the joint book runner for JD.com’s issuance.

Both enterprises said the proceeds will be used for share buybacks, which are expected to boost their stock prices and show some positive signs in the capital market for other Chinese tech companies, Selina Cheung, co-head of UBS Asia equity capital markets, said Tuesday.
