This is actually a long-expected runup from a TA point of view. MACD has been showing positive divergence for months in daily chart. In the weekly chart, after this week, a building Golden Cross (strong BUY signal - see the red circle in the figure below) will definitely draw everyone's attention in the long run.
SP briefly touched $0.63 (Bollinger upper band) and closed at $0.56 - very strong. It should adjust itself in the next several days. In my opinion, as long as it stays above EMA(10), another Golden Cross (EMA 10 crossing 20) will be in the horizon any time soon .
Looking forward to coswil's opinion.
Hold with confidence, still.
