VCNS holds 40% global equities and 60% bonds — the textbook "conservative" allocation. 0.24% MER. Designed for retirees actively drawing down portfolio income, or risk-averse savers within 3 years of retirement. The 60% bond allocation prioritizes capital preservation and predictable distributions over growth.
If you're withdrawing 4%/yr from a portfolio and stocks drop 30% in your first 3 retirement years, you can deplete a 25-year nest egg in 12. This is "sequence-of-returns risk." VCNS's 60% bond allocation mathematically reduces this risk by ~40% vs an all-equity portfolio. The trade-off: lower lifetime returns. But you reach retirement; the worst-case scenario is no longer a concern.
VCNS is a niche product, but for the right user (65-75 actively drawing portfolio income) it's the math-optimal answer. The 60% bond allocation virtually eliminates sequence-of-returns risk in exchange for ~2% in long-term return. For most accumulators it's too conservative — use VBAL or VGRO instead.
