Thats one impressive trend, but like all good trends they eventually come to an end. Counting from the 2008 lows I am working the idea this stock is tracing out an impulse wave, currently it appears to be in wave 5, and a closer inspection suggests its possibly now in a 5th of 5th, so the essentially the last wave of the whole move. A strong reversal back under 155.00 is needed to suggest a possible peak in place.
If you happen to own this stock, then I suggest maybe sticking a sell stop at that area and protecting your gains.
