Something very fuzzy about your example and math. First of all in your example, what is the price per share?
At $1 pps you have one million shares, and if your share count goes down to 10,000 shares that means it was a R/S of 100 to one. Horrible. Nobody is discussing anything even close to that. And our share value isn't even close to $1, if only it was.
But if you suffered this split, the share value in your example would now be $100. So you still have value of $1,000,000
The percentage of increase of a share at $1 going up a penny is not a valid comparison of a share at $100 going up a penny. The percentages are not the same. In fact the change is equitable to the reverse split ratio. So to compare a one dollar stock going up 1% (.01), you would see a $100 stock going up 1% would be a rise of $1. Voila!
