XRO has had a fantastic run up over the past 5 or 6 years. It recently retraced (possibly in sympathy with Wall Street revaluing tech stocks generally. I see this as an Elliott Wave 4 and with price having broken above a downtrend line it could be started up on Wave 5 - which would normally see price go back above $160 before turning down again.

Note that the downtrend isn't a valid downtrend line because it can't be fitted to three peaks, however I'm electing to see it as a usable trendline. Could be a good long-term hold.
