BMY will pay well long term with its seemingly safe dividend of +4%. Do yourself a favor and don't go all in at once especially with this cliff nonsense a real possibility. As long as interest rates remain this low, BMY is an inviting SLOW way to see your investment grow. I bought back in around 25 a few years back and the dividend reivestment is very worthwhile. If you're looking for a quick buck, look elsewhere.
Unfortunately, you can argue that either way. If your committed to BMY, do it!
I don't believe there is any "good" move in the market while Obama is destroying Americas finances.
Best bet, is to hoard cash/gold
