Build portfolios with evidence, not instinct.
aperature lets you research thousands of assets, construct portfolios, and test them against decades of market history — before a single dollar is allocated.
See what your portfolio would have survived.
Change the allocation. Change the outcome.
Drag the sliders and watch decades of simulated history rewrite themselves. aperature rebalances the rest of the portfolio automatically so you always stay fully invested.
Simulated from 26 years of monthly market data. Rebalanced monthly. Past performance does not guarantee future results.
Find the portfolio between risk and reward.
Every dot is a simulated portfolio. The curve is the efficient frontier — the set of allocations where no extra return comes without extra risk.
Research without leaving the workflow.
Fundamentals, valuation, and risk for any of 8,000+ assets — wired straight into the backtesting engine. No tab-switching, no exports.

Why TLT and GLD earn their seats.
Hover any cell. The low — sometimes negative — correlation of bonds and gold to equities is what turns a drawdown from a −45% event into a −30% one. That's the whole game.
One portfolio. Multiple realities.
Three strategies, same starting capital, same 26 years of history. Hover the chart to compare them month by month.
