Constellium's 15min chart shows RSI overbought and KDJ death cross.

Constellium's 15-minute chart indicates a potential shift in momentum towards the downside, as the Relative Strength Index (RSI) has reached an overbought level and the KDJ indicator has formed a death cross. This suggests that the stock price has risen too rapidly and is no longer supported by fundamental analysis, with a potential for further decline.
