let's say stock closes up 5% today what are the chances that we have another 5% or more tomorrow, I don't see the change in value here just a split, if a small investor had $3,000 to invest couldn't they have bought the same share or amount of shares what am I really missing here?
It's simple mathematics: If you purchased one share of this stock at $3000 a share, and it goes up $100 in one day, you got $100 profit, i.e., 1 x $100.
However, if you purchased 50 shares at $60 and it went up $100, you profit is $5000, ie. (50 X $100).
Investors/traders are betting that the more shares outstanding will make the stock more liquid and the demand will send the price skyrocketing, and if it does you'd rather be multiplying that increase by 50x rather than 1x.
