The New York-listed company’s shares closed up 13% at $1.06.
The move by JA Solar follows similar repurchase programmes at peers LDK Solar and Yingli last year, after weakening demand and falling profits led investors to sell off shares.
JA Solar has been trading at its lowest valuations since 2008, a likely trigger for the share buyback, say Nomura analysts.
The stock fell 11.4%
