"Ya, I forgot to add psychological factors into that list. But that also goes both ways"
Of course, I didn't mean to imply that breakouts can only happen on the upside. But even a downside breakout can happen only on TA reasons. There are plenty of traders who buy ONLY on breakouts and conversely look to sell ONLY at breakouts. It just depends how many of each there are at the various levels to determine who wins and who loses. Same with new highs/lows, swing highs/lows etc. Any staircase trend is an example of this. No way staircase trends are trading on fundamentals only. Supply and demand at the various inflection points, which can be very emotional, area much bigger factor. New bulls and bears are created just by the markets reaction to these points. If fundamentals ruled stock price, how can Shake Shack be valued at 10 times sales and Buffalo Wild Wings at 2 times sales?
"Breakouts occur for a variety of reasons. Good news, a massive word of mouth campaign, economic factors, inflation rates, interest rates, competitor progress or decline, insider knowledge between colleagues etc"
You're leaving out probably the most important one: technicals themselves. Swing highs and lows, support and resistance etc....all these conditions effect trading at the various levels, certainly at breakout levels. If the pullback from a prior high is weak, that itself can lend strength to a subsequent attempt at a breakout. We've had two consecutive inside days as trading during this 'correction' dries up. The next move could tell a lot as to future direction. A breakout without any of the conditions you mentioned is definitely a possibility.
How does the statement "the share price can drop by 70% or more" qualify as "facts and no fiction"? Isn't that more "speculation, and no facts"? I mean, if I say "share price can rise by 1000% or more" does that also qualify as 'facts and no fiction"? Not to mention you're just parroting a Seeking Alpha article anyway. Did you read the other S.A. article that predicted peek sales of 2-73 at $9 BILLION a year? At even just a 4 times sales metric, what do you think that might do to the market cap?
