Vistra Energy Corp VST has made an impressive upward movement from $21.50 to $27.25. It is extremely overbought and due for a small retrace. Both the MACD and RSI/EMA have crossed on the daily chart- indicating a shift into downward momentum (MACD) and a loss of support for being so overbought (RSI/EMA). A retrace to $25 is my conservative target for a 1 month time-frame.
