Home-country bias

Home-country bias is the well-documented tendency for investors almost everywhere to keep the bulk of their portfolio in their own country's market, far beyond what that market's actual size in the global economy would justify. It isn't a Philippine quirk. American investors overweight US stocks, Japanese investors overweight Japanese stocks, and Filipino investors overweight Philippine stocks, all for the same underlying reasons.

The pull toward home is easy to understand. Local companies are the ones you recognize from billboards and malls, local news covers them constantly, and buying and holding pesos feels safer simply because pesos are what you already think in. None of that makes the local market a better investment, it just makes it a more familiar one, and familiarity gets mistaken for safety more often than it should.

The problem is that home bias concentrates risk in a way most investors don't fully notice. Your salary, your business prospects, your real estate, and your local bank deposits are already tied to the Philippine economy. Stacking most of your investment portfolio on top of that same economy means a single country's downturn, a weak peso, a slow GDP quarter, a local political shock, can hit nearly everything you own at once, not just one slice of it.

A Manila-based professional has a peso salary, a condo in Quezon City, a peso savings account, and a stock portfolio that's 100% Philippine equities. When a period of weak local growth and a soft peso hits at the same time, the professional's job security, property value, and portfolio all wobble together, because every part of their financial life runs through the same economy.
