Proprietary Technology
Built Different.
Built for Investors.
BestFolio isn’t just another strategy tracker. Our research team has built proprietary technology that no competitor offers.
SmartLeverage™
Amplify returns without amplifying complexity.
Apply mathematically optimized leverage to any strategy with a single parameter. Our engine finds the sweet spot between growth and risk for each strategy individually, so you get more from your capital without guessing at leveraged ETF combinations.
SmartBlend™
Four ways to combine. One optimal portfolio.
Combine multiple strategies into one portfolio, optimized four different ways. Equal weight, risk-balanced, volatility-targeted, or maximum risk-adjusted return — compare them side by side and pick the approach that fits your goals.
SmartStack™
Layer strategies like a pro. No margin required.
Build multi-strategy portfolios by stacking independent sleeves, each with its own rebalancing schedule and weight. Designed for tax-advantaged accounts where each layer runs independently — see combined analytics and execution-ready positions in one view.
ETF Proxy Chains
30+ years of data. Even for ETFs launched yesterday.
Backtest with three decades of validated historical data, even for recently launched ETFs. Our proprietary data pipeline stitches together verified historical proxies automatically, so you can see how strategies would have performed through every major market crisis.
UCITS Translation
European investor? We speak your language.
One click translates any US ETF allocation into UCITS-compliant alternatives with confidence ratings. Get actionable signals with ISIN codes you can enter directly into your European broker — no manual research required.
Execution Rollup
Eliminate dust positions. Trade what matters.
Running multiple strategies? Our rollup engine merges your allocations into clean, execution-ready positions. Small holdings below your threshold get consolidated into the closest matching asset — no more impractical $50 trades in a $50,000 portfolio.
Signal Backfill
Know what to hold now. See what’s coming next.
Every strategy shows two clear signals: your active allocation for this month and a forward-looking preview of next month’s likely changes. No ambiguity about signal dates, no confusion about whether a signal is current or stale.
Daily NAV Extension
Your dashboard updates every morning. Not every month.
Track your portfolio’s month-to-date, year-to-date, and period returns in real time. Performance data refreshes every market day, so you always know where you stand — without waiting for the next monthly backtest cycle.
Walk-Forward Validation
Don’t just backtest. Stress-test.
Our walk-forward engine splits history into training and testing windows to detect strategies that are overfit to the past. See genuine out-of-sample performance, so you can trust that what worked historically will hold up in live trading.
TaxStack Engine
Estimate tax impact before you trade.
Model different holding periods and account types to understand your tax burden before executing. Get concrete savings estimates and strategy-specific suitability assessments tailored to your tax-advantaged account structure.
Price Integrity
Every data point verified. Every backtest auditable.
Multi-source validation, automatic anomaly detection, and transparent data lineage for every backtest. When underlying data changes due to corporate actions, the system flags it — so you always know your results are based on clean, verified data.
