Let's check out the charts to see if there is a chart point we should be respectful of.
In the daily bar chart of SRPT, below, we can see that prices have been stuck in a sideways to lower trading range since June of last year.
Prices have crossed above and below the 50-day moving average line several times over the past nine months. SRPT tested and broke the rising 200-day moving average line in December and January and again this month.
The daily On-Balance-Volume (OBV) line shows a peak back in June, followed by a slow decline. A weak OBV line tells me that sellers of SRPT have been more aggressive.
The trend-following Moving Average Convergence Divergence (MACD) oscillator has been moving around the zero line the past twelve months, but recently has been pointed down to the zero line and perhaps a new sell signal.
In this weekly bar chart of SRPT, below, we can see that buyers of this stock two years ago or three years ago have huge gains. Maybe some of them have been sellers over the past nine months.
Prices are holding right on the rising 40-week moving average line. The weekly OBV line is flat and the MACD oscillator has rolled over towards a fresh, take-profits signal.
In this Point and Figure chart of SRPT, below, we can see that the software is projecting a possible downside price target of $107.
Bottom-line strategy: I don't follow the fundamentals behind SRPT, but the charts are telling me to sell.
