Paul, take what i say with a grain of salt but I recall reading either an academic paper , or a synopsis of one which indicated that having 30 different stocks essentially gave one virtually all the diversification one needed- like a 95% confidence level sort of thing so I am surmising that they selected 30 as a non-specific number for diversification rather than being specific to this methodology. BTW does the methodology say why they rebalance after 12 months? that seems strange to me and arbitrary.
