Hi Tim...Charts are not perfect predictors and aren't really designed for that.....We Chartists use crystal balls for our predicting ;):D
Charts are reasonably good at picking up subtle investor behavioural changes and when it happens at say pre-announcement time it catches the chartist's attention..
At this stage the Chartist turns detective and tries to sort out if that investor behavioural change is:...
1....mostly due to possible insider trading (legal ones:)and illegal ones:mad ;:) and privileged released researched data stuff to clients ...which is a very good signal......
.....or....
2....a not so good signal..e.g when the company's shareholders are mostly the "excitable/emotional investor" type that speculates/worries, punts..
...and....
3....sometimes the Market and Chartist alike are taken completely by surprise e.g when TA can't detect anything (there is no investor behavioural change) such as an out of favour companies which are completely leak proof.
You get to know which companies are which (consistent historic behaviour)..so using TA detection with these certain companies around announcement times is usually a good bet :D
As for AIR...It's difficult for me to understand...It's volatility is its only constant and why should that be?... looking at the shareholder list at least 90% of the shares issued are "managed"
