CNBC - May 31 -In its IPO prospectus on Friday, health-tech company Doximity - founded in 2011, often described as the LinkedIn for doctors - said it's allocating up to 15% of shares in the offering for physicians through a "reserved share program." That means eligible doctors can get stock at the same price as the select group of institutional investors, who so often benefit from the IPO pop because they get an early allocation and don't have to wait for trading to begin.
