Two large trades21 Nov 2016 10:43
I see on 17th & 18th November tradesof
2,500,000 shares.
The first listed as a sell definitely was a sell.
The second listed as a buy and could have been
either a sell or a buy.
It looked a good price for a sell of such a price.
As they were two sizable trades of identical size and price,
it is hard not to conclude it is the same seller/buyer.
Conclusion - Someone is offloading.
