If you had to choose now, would you rather have $LMT-3.9% or $RHM.DE3.0%stock in your portfolio ?
While $RHM.DE3.0%stock is up significantly this year, $LMT-3.9% stock is down quite a bit. I would prefer Rheinmetall because of the current situation, but the stock is very overvalued right now.

Lockheed Martin
LMT
Despite the high price, I still find $RHM.DE3.0% more interesting. The stock may have risen now, but the company still has huge potential. With $LMT-3.9%, the big risk is Musk, who can negatively impact this company.
Given the price, I would buy $LMT-3.9% now because it is cheaper, but I imagine $RHM.DE3.0% will continue to rise for some time.
