GILD BUY BACK比我开始以为的要多，新闻里说买了2B那个估计是下半年的数字，今年其实买回5.3B。

As of December 31, 2014, Gilead had $11.7 billion of cash, cash equivalents and marketable securities compared to
$2.6 billion as of December 31, 2013. During 2014, Gilead generated $12.8 billion in operating cash flow and utilized
$5.3 billion to repurchase shares.

所以buy back不是我原来以为的动作不大，而是动作比较大，对股价应该有像去年AAPL一样有个强支撑，见低买进会是不错的手段。
现在有18B的buy back 计划，用它手上的现金一下砸个3，5B出去狂扫一阵也是有可能的，再多估计短期没钱了，要发点BOND了。
