This is an interesting thread. I agree that there is no holy grail, even with Visual Analysis. But I will say that there ae definite "conditions" which seem to repeat themselves, and if one can detect what these are, and when these occur, then a profitable system may be established. This takes lots of back testing, time, and patience, but it can be done, just stay with your gut instincts, keep good records, and listen to no one. From what I have seen, and worked with, I can say that it would seem that people are either "fooled" or "discounted with emotion" out of their money, with all the news the internet can conjure up.
With Visual Analysis, one can say that the best time to take a position is when nobody wants the stock. Easier said than done. One must master the elimination of the emotional component completely, otherwise risk being continually led to the slaughter house. I sum up a stock chart as
the best possible insight into the workings of the company that an outsider can get, without being an Insider. I look at news about the stock as event markers used to justify the recent moves in the chart. This is true because all insiders have early positions before the public news is made...always.
If you can ignore the emotional attachment, but monitor and trade on the emotional attachment of others, then you can profit.
Hope this makes sense...cheers D
