 做空真的有罪吗 ?还是有必要回顾一下常识。所谓做空,就是指看到10元的某只股票,认为它会在未来跌至8元,这时就从持有这只股票的人手中借来100股,以10元的价位卖出,得现金1000元。如在规定时间内,该股跌到8元,则再以8元买进100股,并将这100股还给原持有人,这个时候就赚取了200元。如果该只股票涨到12元,到了约定时间,也必须花1200元买进,这是就亏损了200元。

 有专家指出,现在对“能吏”的评价更多是结果决定论。一个干部升得快、干得多就是“能吏”,很少对其政绩背后的过程、成本进行科学细致的分析和检讨。一个热衷于在领导面前表功讨好,或者靠跑、送、要而升得快的干部,干的是面子工程、政绩工程、腐败工程,这算是哪门子的“能吏” ?
