Based on the price he purchased the stock and the amount he sold them for, Jeff's annualized HPR on the investment is 2,395%.
First find the net profit:
= (1,000 x 9.26) - (1,000 x 1.89) - 10
= $7,360
The HPR is:
= 7,360 / (1,000 x 1.89)
= 389.4%
The annualized HPR is:
= (1 + 389.4%)² - 1
= 2,395%
Note: Taken to the power of 2 because there are two six-month periods in a year.
