German Blue-Chips Navigate a Minefield of Warnings

DAX faces profit-taking risk with extreme RSI at 83.8, while Lufthansa strikes and Hugo Boss profit warning add pressure ahead of key ECB meeting and ex-dividend dates.

The DAX opened the new trading week with modest gains, supported by diplomatic progress in the Middle East and positive signals from Asia. Yet this fragile calm belies a market under significant strain, caught between extreme technical warnings, a flurry of negative corporate news, and a deteriorating macroeconomic backdrop.

A Market Stretched to Its Limits

Beneath the surface, the technical picture is flashing red. The 14-day Relative Strength Index (RSI) is sitting at an extreme 83.8 points, a level that strongly signals the market is overbought and raises the probability of imminent profit-taking. The benchmark index closed the previous week at 23,803 points, leaving it just below the immediate resistance level of 24,000. For chart technicians, a new buy signal would only emerge if the index sustainably reclaims the 24,033-point mark, which coincides with its 50-day moving average on a closing basis.

Compounding this technical pressure is a worsening fundamental environment for equities. The yield on the 10-year German federal bond recently climbed to 3.05%, reflecting investor nervousness ahead of the European Central Bank's monetary policy meeting on April 30. Higher bond yields make fixed-income securities more attractive and tend to drain liquidity from the stock market.

Corporate Stress Tests Dominate the Agenda

This cautious mood is already triggering clear rotations within the index. While shares like Heidelberg Materials and BASF found buyers at the week's close, investors pulled capital en masse from Rheinmetall, sending its stock down 5.74%.

The new week brings a concentrated wave of challenging corporate news. A pilots' strike at Lufthansa is the dominant story, with the Vereinigung Cockpit union calling cockpit personnel across the entire Lufthansa Group—including Cargo, CityLine, and Eurowings—out on a 48-hour walkout. The stock had already lost 3.2% on Thursday following a strike call from the UFO flight attendants' union.

The fashion house Hugo Boss was hit even harder, with its shares plunging roughly ten percent at the open. The company warned after markets closed that both sales and operating profit are now expected to decline in 2026, with improvement not anticipated before 2027. Airbus also lowered its delivery target for the current year, though its shares still gained 1.7% as the move was not a surprise to the market. On the positive side, E.ON (+1.3%) and Bayer (+1.1%) benefited from upgrades to "Overweight" by Morgan Stanley.

Adding to the index's headwinds this week are several key ex-dividend dates, which will mechanically weigh on its price. Mercedes-Benz goes ex-dividend on April 17, followed by Airbus on April 21, E.ON on April 23, and Beiersdorf and Merck KGaA on April 24.

Macro Concerns Loom Large

The broader economic landscape offers little solace. The Spring Meetings of the International Monetary Fund commence in Washington, where the IMF is expected to significantly downgrade its growth forecast due to the Iran conflict and higher energy prices. German research institutes now expect GDP growth of just 0.6% for 2026. Porsche reported a double-digit drop in deliveries, and inflation in Germany sits at its highest level since early 2024.

Later today, Federal Chancellor Friedrich Merz and ECB President Christine Lagarde are scheduled to speak at the annual reception of the Association of German Banks, an appearance that could move markets shortly before the closing bell.

With immediate chart support seen around 23,800 points, the DAX faces a critical test. The convergence of an overextended rally, rising bond yields, and a barrage of corporate setbacks suggests the path of least resistance may be lower. The next major sentiment test for the global economy arrives tomorrow with quarterly reports from JPMorgan Chase, Wells Fargo, and Citigroup.
