I bet Surf had some kind of inside info. Otherwise there is no explanation why would anyone short a high beta tech stock when the market is going sideways or up. When was the last time GOOG acted against the Nasdaq??
You should have waited at least until the January effect lasts and short then. Around 10-15th of January...
And even if you really wanted to short GOOG, why didn't you use your death channel approach? Let's say 430-435 death, below short, above not in the position. (because you don't want to be long). In this case you might loose a few bucks to fluctuation, but you sure lose less than GOOG at $550...
This trade started to remind me when you were short YMs against my strong buy signal and let it ran against you by 130 points. You got lucky with that one and got out at breakeven, but remind you that was your last trade for the year in November, so I guess it had a lasting effect...
A good trader shouldn't depend on luck, that will ran out eventually.
Otherwise have a happy and profitable new year...
