WK just busted through some overhead resistance to new highs. It did so on light volume though, which is always a concern. I'd look for a pullback near 60 on a retest of the trendline to get in. Stopped out if it breaks back down below 58.
These cloud stocks are pretty unpredictable when it comes to these breakouts, they tend to make some overblown moves to the upside, but at some point, people will realize that they are all heavily overvalued and .com 2.0 stocks. So you can hold below 58 if you want, but personally I'll always be skeptical of that.
