Technical Rating and Analysis

5

We assign a technical rating of 5 out of 10 to PRTA. In the past year, PRTA was only an average performing stock in the market. The medium term picture is unclear, although we see some positive events in recent action.

PRTA is currently trading in the lower part of its 52 week range, which is not a good signal. Certainly not because the S&P500 Index is trading near new highs.
PRTA is currently showing a bull flag pattern! A bull flag pattern occurs when prices pull back slightly after a strong rise up. This may be a nice opportunity for an entry.
PRTA has an average volume of 1158450 traded shares per day. This is a good sign as it is always nice to have a liquid stock.
The short term trend is positive, while the long term trend is still negative. So this is evolving in the right direction, but it may need some more time to really turn around the trend.
