Where did you get your RSI reading(which chart term and frequency)?
I show us at 73.61 on the daily 1 yr chart-
high, but still very sustainable(see march-april2011 and dec2010-jan2011) for at least a few weeks.
If we see some catalyst that causes a distinct, high volume, pop, I think it might set us up, but short of that, I think we may still have some running room.
Of course, JMO.
