Now we know why!
If one believes in technical analysis, one understands why the stock price hit a 52 week low.
The market moves ahead of the news.
Some people got or felt this was going to be announced and sold. We had a little stronger volume the last 3 days.
It is possible that PYR opted to release it late Friday night so that it wouldn't hurt the
stock price before the week-end.
Now on the other hand, if, in the future, you see the stock price rising for now apparent reason,
that may also mean that something good is about to be released and will make the stock go up.
That is technical analysis for you.
