Asset Allocation
Domestic
- 48% Total Stock Market (UK)
International
- 24% World Total Stock Market
- 20% Intermediate Term Gilts (UK)
- 8% REITs (USA) *
Notes
(*) If a USA REIT fund is not available, a broad global REIT fund is a good alternative. US real estate makes up a large percentage of global REITs so the numbers should be pretty close in normal portfolio percentages.
