Got your popcorn? The wild ride for the summer's blockbuster stock, AMC Entertainment, got even crazier on Thursday (Friday in Manila).

The movie theater company's stock plunged nearly 40 percent in the morning after it announced plans to sell 11.6 million shares to raise cash while warning buyers they could lose all their investment. But it erased the loss in just a few hours. After the stock sale was complete, it climbed above the record closing price it had set a day earlier, only to sink back to a 17.9-percent loss by the end of trading.
