How We Invest
Every decision in the investment process is designed around one constraint: the time horizon of the underlying demographic shift.
See Our PerformanceWe Start With the Household.
Most equity analysis begins with a company: its earnings, its management, its competitive position. We begin with the household. Before evaluating any single security, we ask which demographic forces are reshaping demand in a given sector over the next decade, and which companies are structurally positioned to benefit.
Instead of screening for stocks and then checking whether they happen to benefit from demographic trends, we first map the demographic structure of the economy and identify the sectors and sub-sectors where that structure creates durable demand, before finally conducting rigorous company-level research within those bounds.
Company analysis begins only after the demographic structure of the sector has been mapped. The thesis narrows the research agenda before fundamental work begins.
We hold between 38 and 45 positions. Concentrated ownership requires a smaller research universe and a higher conviction threshold per position.
Demographic Shifts Are Structural.
A person born in 1960 will turn 65 in 2025. The demands that person will place on health care, financial services, and consumption patterns over the following two decades are calculable, and the equities positioned to benefit from that demand growth are identifiable today.
Our strategy is to identify these structural shifts before the consensus recognizes them as investment themes, and to build high conviction positions around those shifts.
Population data from the Census Bureau and Social Security Administration is publicly available. The opportunity lies in the conviction to act on a decade-long thesis before consensus catches up.
The Market Misprices Time.
Capital markets are organized to price the next quarter accurately. Analyst models rarely extend beyond a five-year horizon, and the further out a projection runs, the more aggressively it is discounted. This is rational for most investing, but it is not rational when the underlying driver of returns is a demographic shift that compounds over a generation.
Mercury was founded on a single observation: demographic trends are among the most predictable forces in economics, yet the market, oriented around quarterly results and annual performance reviews, systematically underprices them. We invest in the gap between the duration of the opportunity and the shorter horizon the market watches. The same structural pressures that create the mispricing keep it in place long enough to be worth acting on.

Cost Efficiency Compounds.
Most performance is measured gross of taxes and transaction costs. For a taxable investor, those deductions are meaningful and they compound over time. A portfolio with high annual turnover generates realized gains that add to the tax burden year over year. Mercury's strategy, by holding positions until the thesis resolves, defers that liability and reduces transaction drag. The result is a structural cost advantage that accrues to the investor quietly, over time, and regardless of market conditions.
