BTM is up huge today as well. Maybe PT is consolidating and going to buy out TNE and BTM. They are already the largest shareholder of each and they have a lot of cash after TEF bought out VIV last year. I have been hoping for a while that TNE would buy out the rest of BTM that they don't already own. Something is happening for both BTM and TNE to be up so big on the same day.
Found it on Dow Jones. TNE consolidating all four listed companies into one single company (BTM) which they will rename Oi. They will go from four companies with seven stock listings to one single company. It should be huge with 25 to 30 billion in revenue. I think TNE has revenue of about 18 billion and BTM has around 6 or 7 billion alone so should be big. Should save a lot of money in the consolidation. Very happy with the idea.
