GILD BUY BACK比我開始以為的要多，新聞裏說買了2B那個估計是下半年的數字，今年其實買回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不是我原來以為的動作不大，而是動作比較大，對股價應該有像去年AAPL一樣有個強支撐，見低買進會是不錯的手段。
現在有18B的buy back 計劃，用它手上的現金一下砸個3，5B出去狂掃一陣也是有可能的，再多估計短期沒錢了，要發點BOND了。
