When majority of the flock of smart birds were outflowing as tsunami, it is obvious based on the FFA flow that a lot of retailers were trying to catch MyEG stocks which had discounted by more than -50% thinking it is cheap.
This resulted in the price down to be disproportionate compared to the funds flow outflow, i.e. outflow tsunami got out at decent prices because fools' monies rushed in aplenty. Based on thousands of precedents worldwide, selling is often far from ended for such a funds flow outflowing stock, especially when it is evident that many retailers bought a falling knife. Prices are often able to further half price again after an initial half price.
