Shares in Barbie toymaker Mattel have jumped almost 20% on reports rival toy giant Hasbro is considering a takeover.
Shares in Hasbro, whose brands include Play Doh and My Little Pony, are also 7% higher in New York.
Last month shares in both companies fell after a warning that the bankruptcy of retailer Toys R Us could limit sales.
The two companies are among the world’s biggest toy makers. Mattel tried to take over Hasbro in 1996.
