The "test" will be if that gap closes under $51.5 and then if $49.5 gives or not. If the market as a bad stretch here in the near future, I think that MRK with one of the weaker charts on the Dow, will "yield"....By the way, I should add that the stop suggested on that 9/10/03 post (#msg-1422587) at $56.75 can now be lowered to $54.5, thus the risk is really quite minimal.
