I will place my bet beside them on this one.
I did a quick search "Vanguard Group 13F".....and YES they have increased their holdings by 13% to 312,820 shares...Whale Wisdom site.
Sentiment: Strong Buy
I just looked up Vanguard Gourp Inc's most recent 13-F HR for quarter ending 3/31/13 and they have $912,868,823,000 assets under management but not a penny invested in AFFY.
Are you really this dumb or are you just acting dumb???
