How do you  solve for holding period yield?
 Holding period return/yield is calculated on the basis of total returns from the asset or portfolio – i.e. income plus changes in value. It is particularly useful for comparing returns between investments held for different periods of time. where t = number of years. Returns for regular time periods such as quarters or years can be converted to a holding period return through the following formula: (1 + HPR) = (1 + r1) x (1 + r2) x (1 + r3) x (1 + r4) where r1, r2, r3and r4are periodic returns.
