The reason for the distribution of open interest between Jan and Dec is that Jan's didn't come into existence until about 9 trading days ago so for liquidity purposes, players will always prefer the ones with the biggest open interest. Unless there is some correlated move in TEVA, the move is not event based IMO. Although, the options IV suggest a big move (+/- ~1.5) is possible by weeks end as IV went up another 10% compared to Monday. So options player are starting to price in a binary event before expiration.

However, I see no such pricing signals in either TEVA or TEVA options.
