I now have a PEA at BoursoBank to invest in shares and ETFs and will be ready to move it to Helios if it remains advantageous in terms of costs and profitability! For the CTO I will set it up later because everyone starts by investing in a PEA in view of its advantageous taxation! I like to lend my money to companies that make good things out of it

Yes I think it's a good idea. I want to buy shares on carbios

Indeed, to my knowledge, there is no PEA specially designed to accept actions from ethical companies.
