The fundamental analysis of this is fairly easy. Mergers are good for stocks. Why? Because it usually means increasing profitability. Why? Because it oftentimes leads to reducing inefficiencies and eliminating two teams that could be consolidated into one whether its with commercial banks, foreign exchange desks, etc. This merger would lead to the cutting of 30,000 jobs in Germany which would clearly help push the mega bank in a positive direction towards profitability. If talks progress positively, expect both Deutsche Bank (bars) and Commerzebank (pink) to edge up. But let's not forget, these two banks' stocks have been in the gutter since the 2008 Financial Crisis and both greatly underperformed the DAX (dark blue) and the Eurostoxx 50 (light blue).
