If you log in with longer pauses in between, the stock trade is for you. Diamond stock trade is not worth it.
Example from my last company upgrade:

That are the lvls I could afford when leveling all girls evenly. If I would not have hired Charlotte, but Anika instead, I would have needed almost 100 lvl more for the company sell goal. Of course, I could have almost doubled my income, but insane number growth does not work this way. To get +5 lvl on every girl to have 55 more levels you need more than double money.
