STML has formed a classic bullish divergence in which the price is making lower lows while the oscillator associated (in this case the RSI) is making higher lows. Another 'hidden' version of this exists and i am doing my best to try find an example of this.
STML seems at the beginning of an uptrend but at the moment it is in a corrective phase. I'm expecting a bounce on the area posted on chart for a new leg up. A breakdown of the rectangle on chart invalidates this setup.
