Speculative short on BOEING

BOEING lends itself for a speculative short position as the price has reached a long term resistance line from the tops in 2007 and 2015. The 2015 top was also the 1.618 fibonacci extention from the top in 2007 en the bottom in 2009. Be carefull with a short position though as there no indicators yet of a weakening of the current uptrend. The price trend is upwards, and both the MACD and the RSI do not show signs of weakening (bearish divergence).
I do not have a position in BOEING.
