Reverse split

"...
A reverse stock split is also called a stock merge
...
A reverse split is the opposite of a stock split.

"

stock split 就是把股票分割, 例如一百股變兩百股, 股價就會減半;
reverse split 就是相反, 兩百股變一百股, 股價變兩倍.

Reverse stock split 可能是為了提高股價, 有些雞蛋/水餃股(penny stock)
為了讓股價回升 會採此方法; 也有可能為了集中籌碼 將一些零股(?)洗出來 ...
