Greactec 的 roic 才33.2%，p/e 70 多，正常的 investment bank 不会再買，因为roic 跟P/E 不對称, 只有推上去出票.
反覌MFCB 的 roic 43%, p/e 少过 15，Investment bank 只会压着吃票，吃夠了，就会推回上去. 一个股的Roic 及 p/e ‘多數’ 相向而行，高低的差别不大. 買greactec, 用这么大本錢去賺小錢，花不来！有賺祝你好運........

四大手套股也被 short sell, 有些IB 希望買多点便宜票，只有用short sell 的方法，才可force 那些不能及不要抓票的人cut loss 或 離場. 因为很多人不明白 quality business which have an ability to generate return on invested Capital that is substantially higher than the cost of capital, high roic is also mathematically linked to high cash flow generation, so IB like this type of company and driven by longer term outcome in the business rather than the short term stock price behaviour.......over longer term IB are the winners.......
