No you can't visit Ari-Yhilina after you have returned from Ardford before the Battle of Yhilin, only after. You can do some of the investments later (for instance you can buy Premium Steel any time that you're in Ari-Yhilina, you can invest in the Bank in chapter 4), but many others are not available after you depart for Ardford.
