As I noted in my recent trading lesson, the Spyder Trust ( SPY) had two sharp double-digit rallies in 2012, but each was followed by almost a double-digit correction.
That much was clear from the very first point against Djokovic - a visibly nervous Berdych opening proceedings with a double-fault - but against Roddick he looked sharp and confident from the outset, clipping a beautiful forehand winner up the line in game one.
