$DTE (-1,29%) How far can she still walk?

First of all, I am invested and am not planning to sell. I would just like to hear your opinion on the share.

The last time I bought it was at €24, so I was worried about how far the rally could go. But I didn't really care because even after the purchase my equity was still just under €20. When the 26€ came I had already put some cash aside as I was speculating on a correction of 15-20%. In the last 2 weeks the 26€ were secured and now the share price is at 26.7€. The current figures are convincing and the outlook is also good. I like to compare it with its US sister, which is traditionally valued somewhat higher. It now has a P/E ratio of around 25.5 Telekom Deutschland is at 26.9. Can this upward trend be maintained? the new financial report will be published in 2 months. Where do you see the share until then?

My prediction is that it will lose a little ground but somehow hold €26.

Edit. Not €26.7 but €26.87
