Topline Genomics powerhouse Natera surged in trading Friday following a blowout second-quarter earnings report and a strong revenue beat, sending the stock to an all-time high and its co-founder’s fortune even higher. Natera’s market capitalization jumped to $46.1 billion after ending July around $38 billion, according to market data. Rabinowitz holds roughly 2.28 million shares worth approximately $717 million, as well as options and vesting restricted stock units, according to the company's proxy filing and insider transaction disclosures. That is how much Natera shares have grown since the start of the year, when they were priced around the $228 mark. The company’s lowest closing price this year occurred in late March, when shares fell to $182.65.
