@Acer 股票的话不知道是不是因为reverse split
怎麼檢查是不是 reverse split?
什麼情況下會發生 reverse split 呢?
reverse split本身是什麼也不太理解
@Acer 很难根据图来直接判断，逆分拆就是把流通股票按比例合并，比如原来我手上一百股变成了一股，导致价格按比上升，一般见于市场下跌，动机很多，其中一个就是防止公司被delist
There are no value indicators on the y-axis, so we don't know if the bottom of the chart is zero or if the chart actually shows a narrow price range. The volume indicator shows an increase in volume at the time of movement and at other points before and after the movement, however, that also it difficult to judge because the chart is only for a few days so we can't tell if that volume is typical for that stock.
Where did this chart come from? Did you create it yourself?
That's a 3.6% move. Not extraordinary, especially if it's a high-beta stock.
It's not a split.
If you can't find any news that would account for the move, it may be related to taxes. Buyers who are thinking about getting into the stock may purchase right before the end of the year so that they get a tax advantage.
The very sudden jump is probably due to the exchange opening and brokers settling orders they got during the time when the market was closed. (I'm not sure what timezone is shown or which exchange it trades in.)
例：
原本持有100股每股1元
现在变成50股每股2元
于是股价“貌似”跳空上涨一倍
个人习惯：
但凡看到并股跳空，直接88…
（事实也证明，这个股价在并股后确实暴跌）
ps 个人不喜欢“逆向拆股”这种叫法，所以直接叫“并股”
@Acer 期货合约么
