Dude I calculated that if you compound your $2000 on 80 business days (which is roughly the 120 calendar day period) with an average daily profit of 1,3%, the value of your assets will be roughly $5548 on the 80th Day
I wish I had that money to invest

I just progressively invested $500, so can't buy a share every day and can't maximize the compounding effect (yet). Above $2000 you reach the maximum compounding effect (supposing a minimum of 1% daily profit) because you can buy (at least) a new share every day :p
Seems like I'll have to go sing in the street to get money faster...
The hard times of being a student...
EDIT: just to compare, if you cash out every day with the same profit rate you should get approximately $4106 on the 80th day, so $1442 less.
