How Should You Invest Your MPF? Three Lessons in Asset Allocation

This article is a rewrite of a report from October 2012.

MPF — Hong Kong’s Mandatory Provident Fund, in force since December 1, 2000 — requires every employee to build an investment fund for retirement. It is not a savings plan: portfolio performance hinges on asset allocation, adjusting the equity-bond mix across the life cycle. Simple in theory, yet most members lack the time or interest to study markets. Three lessons for managing your MPF portfolio.

How does MPF work?

Your monthly contributions buy into funds across five types — equities, bonds, mixed-asset, guaranteed and conservative — each with its own risk-return profile. Before picking, know what you are buying: equity funds are aggressive, bond funds steady, mixed-asset blends the two, guaranteed funds protect capital conditionally, conservative funds are near-zero risk and near-zero return. Your age, years to retirement and loss tolerance set the mix.

What is Buffett’s first rule?

Rule one: never lose money. Rule two: never forget rule one. Warren Buffett’s dictum matters for MPF investors: controlling downside is everything. Losses usually come from four mistakes — buying tops, deteriorating fundamentals, undiversified idiosyncratic risk, and mishandled market risk. MPF’s monthly contributions dodge the lump-sum-at-the-top trap: dollar-cost averaging means expensive top-buys get offset by cheap bottom-buys.

What is systematic risk?

Diversification tames company risk, not market risk. Idiosyncratic risk — company and sector risk — balloons with concentration but dissolves across several fund types. Systematic risk is market risk: no diversification cures it, only endurance. Decades-long monthly-contribution plans like MPF are built to ride out volatility with time; most long-horizon investing ends positive.

Why do investors buy high and sell low?

They sell in panic and chase in euphoria. The columnist’s warning: investors most easily dump at maximum fear and buy at maximum optimism. MPF’s small monthly amounts make buy-high-sell-low hard early on — but after years of contributions pile into a large sum, market swings bring real psychological pressure. The advice: find at least one trustworthy adviser with a solid track record.

What is the lesson from 2012?

Allocation beats timing. Written in 2012 under the euro-debt cloud, the column’s logic still holds: MPF returns come not from calling markets but from asset allocation, disciplined contributions and time. Before watching the market, answer three questions — how old are you, how much can you lose, and what is your equity-bond split?
