Jay1000, the mffais data has been shown to STILL mix WM and WAMUQ ever since the conversion of the symbols. Do not rely on them as a viable source of information.
I'll 'bet' that if you dig deeper, you'll see that they added WASTE MANAGEMENT now known as WM
looks like they bought it at the end of january, but it was filed last friday? i'm not sure how to read mffais, but "filed" and "as-of/on" is distinguished as two seperate items.
