The ongoing war in Ukraine has driven Rheinmetall's stock to new record highs since 2022. Today, unexpectedly aggressive remarks from French President Macron led to a volatility explosion, which could signal the end of the uptrend. Year-to-date, the German arms manufacturer's stock has risen by more than 72%. A double top formation is evident in the OBV, which is noteworthy as the OBV has consistently confirmed the previous increase. Therefore, in our view, a good opportunity for profit-taking in Rheinmetall stock has arisen. Here we present a short idea, but we emphasize that Rheinmetall's stock is in a very strong uptrend, making short positions particularly risky. Nonetheless, in our opinion, investors should consider realizing at least a substantial portion of their profits at this price level.
