Shares of Angie's List Inc. soared in premarket trading Wednesday after the Financial Times reported that the consumer reviews service was considering a sale of its business. The newspaper, citing sources it did not identify, said Tuesday that the Indianapolis company has hired bankers to help it explore strategic options, but it was not committed to a sale and may decide not to pursue a deal. Company spokeswoman Cheryl Reed declined to comment on the report. Angie's List provides online access to business ratings and reviews.
