BofA (BAC) bounced back to the top of the list of most active options after the bank announced plans to repay $45 billion in TARP funds. BAC is up 2.6 percent to $16.06 (but 4 percent off its best levels) and the best gainer in the Dow Jones Industrial Average mid-morning Thursday. In the options market, volume is already 658,000 contracts, or roughly 2X the average daily. The top trades of the day include two blocks (15,380 and 12,446 contracts) of Dec 17 puts at $1 and 95 cents on the ISE. The block of 12,446 contracts is an opening customer buyer, according to ISEE data — perhaps a hedge. 97.5K Dec 17 puts now traded vs. 37K in open interest. Dec 16 puts, Dec 16 calls, and Dec 17 calls are seeing heavy trading as well. Meanwhile, implied volatility (average) is at 53.3, and not much changed today, as players in the options market brace for BofA’s next move.
