my guess is that it is some insto shorting the stock. Given the severity of the decline this close to 1H results, buyers are nervous and are sitting out, which amplifies the impact of the short trade. at some point, the insto will have to cover its short position and that will provide support for the price. Putting it into perspective, only ~4m volume traded today = just a touch over 1% of the stock. patience will pay off!
