>>95642064Anycolor had a scandal and that spooked some investors who sold out of fear that the stock will crash. But at the same the scandal was just online drama in a foreign branch, it wasn't that important as many make it be. Anycolor was down for so long, because they failed to deliver a proper restructuring plan for the EN branch, ultimately they did, they abandoned it and decided to focus on their profitable domestic market, which combined with buy-outs and paying dividends, made the stock bounce.
Cover had a quarterly report. When a quarterly report happens, analyst and traders make predictions, and based on their expectations they buy stock, with the idea that this report is promising, the stock goes up and they make a nice profit. The stock value was pumped from 2700 to about 3400 in the past week by traders. The report came, it was a great report, only not on the level what some analyst expected. Traders know that the stock won't go up any more, so they all sold at the same time knowing the stock will dip. At the end of the day, the stock returned to 2700, which means that pretty much everyone who sold after the report, are the same traders who bought in the week prior to it. Then other traders who were late on the party, and maybe expected a rebound, sold further to avoid losses, so the stock dropped another 300 yen the next day. It may go down a bit more, as those who sold around 2000 mark will try to cash out too, but it should go back to green, but it won't explode anymore by high margin until the next report, if something major won't happen in between.
