The TA actually did turn out to be correct- the share price (as repeatedly predicted by some of those who adhere to TA) went on a longish downtrend from its highs to where we are now. If you did believe in TA you would possibly own a lot less shares at this point. Having said that It all gets down to your personal strategy. If you are a long term investor you possibly would not care so much about TA. If you like to trade and try and increase your holding with the same capital or turn profits along the journey you would likely take closer interest in TA. Again, its a personal thing Mr P.

TA does not predict announcements or their effects, it is predictive of likelihood of outcomes based on numerous studies of how share prices mostly behave given a set of circumstances. Not infallible and no one is Nostradamus but it is a powerful tool to give you an edge in this game in my opinion.

And yes, in a general sense announcements, share prices being strategically propped up (or suppressed or held within a range) , behind the scenes mergers/ acquisitions, product failure and success etc etc and any other of the multitude of unforeseen issues can at times interfere with the TA of any company but overall in my experience TA is the most objective predictor of likelihood. Good luck today!
