QUAFI scores every asset in our universe using a behavioral-finance utility model and runs a constrained gradient-ascent optimizer to find your optimal allocation. Built on academic research, validated on 16+ years of market data — and your first two analyses are free.
Every allocation comes with a backtested cumulative-return chart against the S&P 500 over your selected window. We show you the curve — including the periods where we underperform.
One subscription. No percentage of assets under management, no per-trade commissions, no kickback agreements with brokers. The same engineering institutional clients pay six figures for.
Run two complete optimizations — one guided, one with your own tickers — before any payment is taken. See the engine in action with your own money in mind.
Choose your investment horizon (short / mid / long) and risk aversion (conservative / balanced / aggressive). Two clicks. We translate them into the behavioral-utility parameters used in the optimization.
Either supply your own tickers, or let the QUAFI selector score every asset across S&P 500 equities, US ETFs and Argentine stocks, then build a diversified basket for you automatically.
Within seconds the gradient-ascent optimizer returns the weight of each asset, a cumulative-return chart, KPI tiles (Sharpe, volatility, drawdown), and an actionable HTML report you can download or print.
QUAFI's utility function is derived from Tversky & Kahneman's loss-aversion framework. Every instrument is scored on its full historical return series with separate penalties for downside variance (α₁) and upside variance (α₂), discounted geometrically so recent observations dominate. The optimizer is projected gradient ascent on the same utility, under a per-asset concentration cap and a per-holding floor — so the portfolio is never collapsed to a single name and never holds an invisible 0.1 % position.
Every plan includes the full optimization engine, the downloadable report, and the per-asset detail screen. You only ever pay a flat monthly fee.
All plans bill in USD. Cancel any time from your account settings. The first two optimizations on every new account are always free, before any payment is taken.
QUAFI was started by Agustín Shehadi (Ph.D.) and his co-founder to bring the optimization techniques used inside hedge funds and private-bank desks to the rest of us — without the AUM fee model, without the broker kickbacks, without the black-box marketing. We don't sell securities. We don't take a cut of your gains. We build the math, charge a flat fee, and show our work.
