LNKD is so far (knock on wood) obeying the laws of technical analysis by turning down on the backtest of the uptrend line while simultaneously riding down the downtrend line and still offers an objective short-entry or add-on as long as prices remain below those resistance levels. Just to reiterate, this is a fairly aggressive short trade with a suggested beta adjustment of 0.70.
What that means is that A) one should pass on this trade if it does not fit their trading style or risk tolerance and B) Those that are experienced and comfortable with the inherent risks of such as trade should consider adjusting the position size to approximately 70% of their typical position size for average beta (1.0) positions such as the SPY. Of course these are general suggestions, not specific recommendations and each trader or investor must determine which trades to take (or pass on) and the position size that is commensurate with their own unique risk tolerance & trading style.
