A fixed value security does not vary in price.  It is usually priced at $1 per share.  When you check this box, Advisors Assistant will assume the price is $1 per share.

Rate Of Return And Fixed Value Securities

Money markets will typically receive interest once per month, though their balances may fluctuate between extremes during the month.

If a money market maintains a large value during the month and then has only a small value when the interest is paid, it can receive a larger interest payment than the value at the time of payment.

This scenario can cause time weighted calculations to show a very large return for the cash flow period.

Because of this, all rate of return calculations for fixed value securities are made on a dollar weighted calculation basis.
