In the end, you can only hope that you don't regret it. European shares in the summer sale.

Today I bought the last tranche of Carl Zeiss Meditec $AFX (-4,37 %) today. The reason is of course that I am still convinced of the company, but nobody can say how long it will be before the share comes back to life.

It could probably go down even further, but I have decided not to buy any more from now on as the position is large enough and otherwise my risk management will no longer work.

Overall, I have increased my position size from around 1% to just over 3%, which already represents a clear commitment to a German company, which is known to be particularly volatile.

The same applies to L'Oreal $OR (+1,38 %) here, too, I have finished buying with a buy-in of €365 and have reached a position size that is already approaching the 4% portfolio weighting. The shares will probably continue to fall for the time being, which I will simply have to hold on to.

I would now rather concentrate on other opportunities such as Thermo Fisher $TMO (+1,71 %) where I have already doubled down this month. Here, however, I can well imagine buying significantly more if prices fall.

It cannot be ruled out that, if the market as a whole weakens, LVMH $MC (-1,36 %) and $ASML (+3,19 %) a first purchase could take place. With the four stocks already mentioned here (+ $NOVO B (-2,54 %) ) mentioned here, I believe that the potential of Western European equities has already been fully exhausted.

It's just a difficult case. Europe is currently more attractive than ever before compared to the hot American market. Either you can seize the opportunity of the decade NOW and bet on a recovery of the European economy, then the champagne corks will pop here in two years' time. Or there will be a complete implosion of the European economy (and then the double-digit losses in the portfolio will be the least of our problems)
