NAV stands for Net Asset Value. The market value of all securities owned by a entity, minus its total liabilities, divided by the number of shares issued.
The graph on the side bar is a graph of the NAV, which help us track our online option trading strategy’s performance.
When I started to test this Option Trading Strategy on 6/1/2005, the initial NAV was set at $10.00. So if the currant NAV is at $11.80 that means every $10 invested then would now be worth $11.80. $10000 invested would be worth $11800.
