Lump sum or DCA in the CAC 40?

Are exchange rates taken into account?
Yes. The CAC 40 trades in its own currency; every purchase and valuation is converted at that month's exchange rate. A US asset can gain in dollars and less in euros if the dollar weakened.
Are fees and taxes included?
No: results are before brokerage fees, fund fees and taxes. Your net result depends on the account you invest through.
