CM 的 aone buy signal 挺准, 只不过是量没上去, 今天是 lock up period 最后一天, 明天IPO holder 可以自由地买卖, 那么 aone 的 venture capital, who hold a large position of aone, and insiders, can decide the direction if they opt to sell it to open market or not. But since aone is not much higher than IPO price, I doubt it would cause much fluctuation.

When stock prices "melt up," options-pricing models can get cloudy.
