MathewMartoma's insider-trading conviction upheld

An Indian-origin portfolio manager, who is serving a nine-year jail term for his role in the most lucrative insider trading scheme in the US, has lost his bid to overturn his conviction after an appeals court ruled that there was "overwhelming" evidence against him. Mathew Martoma, 43, was convicted in 2014 for his role as the "central figure" in the most lucrative insider trading scheme ever charged involving $275 million in illegal profits.
