Hi wbosher
Theres a lot more to it than company announcements.
heres a few to consider
What is the Market as a whole doing today
What did the other Markets in the world do last night
If you are looking at the ASX the performance of the USA markets the night before is a good indicator of what will happen today on the ASX and NZX
What do they sell and if its a commodity whats happening to the price of that commodity
Does currency exchange rates affect this company
Are their Announcements trustworthy. You can look back on what else they had to say for them selves and how it really turned out.
The list goes on but heres a couple of links to start with
