Why does Fidelity Select Fundranker have set exchange dates?
Fidelity Select Fundranker’s exchange dates are carefully selected to allow time to distribute the newsletter and to avoid roundtrip transactions, which are discouraged by Fidelity Investments’ frequent trading policy for Select funds. A Fundranker exchange date is never earlier than the second day of the month and is always at least 30 days after the previous exchange date if a fund held for only a month is being exchanged.
