Entries for the fourth round of Watson Wyatt Investment Challenge, in partnership with Financial News and the National Association of Pension Funds, must be submitted in two days.

Participants will aim to achieve the best performance over a notional 10-year period for an imaginary pension fund by stipulating asset allocation and level of risk from a range of options. They will have the chance to opt for a variety of equity and bond splits and allocate equity assets across various regions.
