Lufthansa is leaving the downward trend and can develop upwards. Importantly, there will be more expensive ticket prices from the next few years and that can have a positive as well as a negative impact on prices.
The Dax is recovering from its negative rally and can now move into an uptrend. But the news from England that could provide movement again is decisive. My attitude is Long.
The numbers don't say anything good for Thyssenkrupp. The KGV is currently 1600 and the profit is turning back to a minus. My forecast says you should sell.
