Rio Tinto Plc: gauge fails to break through support level

This week, Rio Tinto Plc tested the lower bound of the trend at USD 41, with a bullish engulfing candlestick pattern shaping up at the end of the week. This is a strong signal pointing to the beginning of movement toward the upper bound of the trend at USD 56-58. Notably, there are no divergences in the RSI, and downward movement may occur, which may be used for buying.
