wipeoff: Over the past five trading days, the following volumes were traded in ITC:
23/11: 14.4 mio
24/11: 14.1 mio
25/11: 4.7 mio
26/11: 19.2 mio
29/11: 30.7 mio
So, put together over 83 mio.
With the likely more than 20 mio. today, the overall volume will represent more than 10% of all ITC shares will have been traded. I doubt that this is just "by chance"...
