No margins of safety for Constellium

From a risk mitigation perspective, you should hold a diversified portfolio. This means stocks in different sectors as well as in different countries.

One the sector and country that I am currently hunting in are US listed companies.

Constellium SE (NYSE:CSTM) is a global aluminum company that IPOed in 2013. It had a challenging performance during the first few years. But the past few years' results seem to suggest that it has turned around.

But CSTM is a cyclical company. It should be analyzed and valued based on its performance over the cycle. On such a basis, I found that there is no margin of safety. I also have concerns about its profitability and financial strength. I would not invest in CSTM.
