I bought into PINK WEAR, for example, when it was at $2000 and got 500+ shares. The stock is now at 3777... a pretty sizable increase if you ask me. Overall I'm up sixty percent because I bought low and waited for my stocks to spike up... It's about patience.
In the R&D section. Setting the level up to high will allow you to improve it quicker but will cost you more money and might make you go bankrupt. Setting it to low will mean it will improve slowly but cost you less.
In the R&D Focus section it lets you choose which part of the phone to improve
