That is another fact that few shorts like to admit. I learned not to short high tech stocks as they zoomed up so quickly that I could not recover fast enough.
It is extremely difficulty to judge the value of EXTR as its growth is fast. Its trend is similar to CSCO at early age, which needless to say, was expensive for the past 10 years.
I do not argue that EXTR is expensive, but it already reports profit which is rare for a recent IPO. According to my prediction (see my previous post), it may hit $110. Therefore I decided to leave when it break the century mark. My new prediction is it will sink to $70 in the near future, and I shall re-enter at that price.
EXTR is still a good stock to hold onto as it has excellent product. I do not worry about the "millions shares of stock" to be released as the insiders will always look after the #1 first.
