New York

SODASTREAM International Ltd's promise to invigorate sales by reinventing itself as a health-conscious provider of sparkling-water machines is eliciting a response from investors: "Prove it."

The Israeli company's stock has plunged 17 per cent in New York trading from this year's high last month, compared with a 2.1 per cent drop in the Standard & Poor's 500 Index in the span. The stock tumbled a record 11 straight trading days before climbing on Friday.
