I'm all about fundamentals. That's why I wrote that post. But the breech of that neckline was a pure T/A indicator that played out perfectly.
Fundamentals always win in the long run, but you have to understand there exists huge amounts of dollar volume moving around daily that use technicals as an intricate part of their algorithms. These build on each other as certain points are established and in a way become self-fulfilling prophesies. I've seen it play out a 100 times. Ultimately they overshoot either up or down, and the stock then reverses.
So all that said, one would be silly to ignore T/A completely, unless you are strictly buy and hold and identify companies as such. Or short and hold like Ackman does occasionally. I guess it depends what your game is and what you are trying to accomplish.
Here's TSLA after it recently went way up on earnings. Are you saying there's something after the jump that is explained by technicals?
