Adding a second Y axis on the right side of the graph?

I am making a line graph to show the performance of stocks.
I need to add the Y axis on the right side of the graph as well. Pretty much a mirror image of the Y axis that is on the left. Any idea on how to accomplish this?

Thanks for your help
