I have heard in a couple of articles and again on cnbc that GOOG or AAPL could replace GM, I would really like to see that take place, however they say that replacing GM with F or TM might be the better way to go since they are in the same industry, who knows, GOOG going into the dow now would be great, stock in reality is only worth around $50 bucks a share, so throwing it in the dow now at $400+ and seeing it sink below $200 or even $100 a share would really hurt the DOW going forward, however I highly doubt its even going into the DOW at this moment.
F is a most likely component. Each DOW component makes up 8 -1 on a DOW calculation. This means that for every point a compnent moves, the DOW moves 8. If GOOG moves 50 points in a day, that is 400 points alone. Correct me if I am wrong
