Let's check and see how the charts and indicators look.
In the daily bar chart of SPWR, below, we can see that the shares made a base around $4 and prices broke out on the upside in June/July and have turned parabolic. SPWR is trading above the rising 50-day moving average line and above the rising 200-day line. Prices are more than twice the 200-day line so they are considered extended or overbought.
The On-Balance-Volume (OBV) has been rising since early June and tells us that buyers of SPWR have been more aggressive. The OBV line looks like it is leveling off in the past few weeks. This could mean that there is more of a balance between buyers and sellers.
The Moving Average Convergence Divergence (MACD) oscillator has been above the zero line since June but the two moving averages that make up this indicator are very close together so we could have a new signal soon.
