Shorters are probably institutions ? ? That one big dump at $1.4, looks very dumb now. .. June is Tax Time, all INSTO swaps shares to record profit/loss. If a stock is sitting on healthy profit, then will lower it and make massive swap trades. That way they can continue to show profit for next year too. That's why some shares drops randomly during May/June. During last week on June, I my self have swapped BIN for Tax Purpose else it is nightmare to keep track of holdings and carry them forward to next year when Tax Rate can be different( depending on Income)
