It is hard to weight the factors without prejudice coming in. It is easy to figure out what to weight if you just look at stock history. Factors like capitalization, management, market support, (meaning sector momentum), trading volume, historical sector risk, trading ranges, # of irons in the fire, geological value etc.. Some investment banks have a good list and methodology. The trouble is how to weight?
TA is more removed. It takes into account that given all those factors, some smart guys want to trade the stock and the truth is in the price out there. Volume and price cannot hide. Can you suss their moves? Momentum crossing its own moving average key reversals, accumulation-distribution, says you can.
Many swear by Camarilla like techniques, which are not that hard to program. If you day trade it works well. You have to watch the hourly moves and manage money, sell quick but it is not that hard to do. If Camarilla is changed to a history of say one month, then theoretically it looks out one month. It is based on a long held observation. Today's price is most like yesterday's, and moves the next day show them selves in the levels reached in the first 2 hours of trading.
