Econometrics an Asset as a Graduate?

Hi guys,

I am new here and looking for some general advice. After working outside of finance and lots of traveling in my 20s, I went to get my masters degree in "Finance and Banking" in Rome, Italy. I am planning on graduating within 12 months, while working as an intern at the German Stock Exchange in Frankfurt in the Index Engineering Department.

My main question: How applicable and relevant are econometric models in the finance world (ARIMA, GARCH, Kalman Filter, High Frequency Models, etc..)?

I am asking because Excel Valuation Modeling seems to be the major talking point not only here, but in anything finance in general. Do my skills I gathered in more econometric fields go to waste or is there an industry that values such skills?

My university's courses are very heavy on econometrics (we use Matlab and R, but learning Python on the side). While I have a bit of catching up to do on valuation, I believe such skills are quicker to learn than pure data science. My ultimate goal (for now) is to work in asset management after I became more seasoned in the finance world, learning valuation and risk management

Which industries should I look at to make an entry into the finance world?

Thank you all for your time, much appreciated :)
