if the Lifeinfader stock ever rose significantly from its negative 500%(scripted) and you were able to get a heads up on that, then the Madoff insider-trading stuff that they're trying to mimick would actually be taking place, not 10-20% on stocks that already have double/triple digit priced shares
82% more than you put in is huge profit. It doesn't matter how much you put in to it, because you're going to end up with 82% more.
Obviously utilizing it when you have a lot of money is better, as you will almost double what you had. If you're only putting $12,000 in, you aren't getting the full benefit. You'd only get about $21,840 back, which is easy enough to make anyway. If you invest $2,000,000, you could get about $3,640,000 back. That extra $1,640,000 is a lot harder to make in the game.
You need to invest a lot of money in to it to reap the benefits. Completing the story will give you a lot of money, so it's perhaps best to leave these missions open until then.
