I think T/A is very interesting, but it isn't a series of charts that determines the SP, it is news that determines the SP and hence the trend lines.  You pretty much said this within the body of your statement.  Your trends, looked at in retrospect, simply demonstrate what happens with a successful company, or for that matter a bad one.  T/A certainly does have a Pavlovian affect on those that follow it, so to that extent it does affect how and when some invest.  Does tv imitate life or does life imitate tv.
