My brother just did the third one, and says he hasn't seen the stock go past 25% increase. Do all the stocks reach an approximate 80+% in profit?
I sold my Debonair a little too early, about 80% for Franklin and was up to 87% by the time I'd switched to my third character. Not sure what the max profit would have been. On the first one, it stayed at 81.5% for a while, sounds like a confirmed peak.
