How to make a quick profit in the stock market?

Here is whats happening my brother found out I’ve been studying the stock market and all.Now he thinks I can make a fortune or something,so much to the point he offered me $100 dollars and told me in shorter words “I don’t care what you do if you can make even 20 dollars with it I’d be happy.” I told him to just save it,the trade fees alone make it pointless,but he insisted.He also keeps talking about giving me money to invest for him I told him no tough as I won’t be responsible for his loses or the such.

We both looked at companies and had some ideas but truthfully I don’t know enough about to want to waste a $100.

For a newbie like myself how can I expect to turn a $100 into say $120—$130 or more if possible?I also figured it could be a nice way to get my feet more “wet”.

I told him think long-term but he just wants to flip some money I guess.

Any suggestions?
