GroupiFi
Correlation intelligence for any basket.
Pearson correlation across seven windows — 30-minute, hourly, daily, weekly, monthly, quarterly, yearly — so you can tell the difference between two names that trade together intraday and two names that only look alike at the yearly zoom.

What you actually get.
Seven timeframes at once
30m up through yearly. The intraday correlation of TSLA and NVDA is not the same as the yearly correlation. You need both.
True diversifier finder
Enter your current book, sort by lowest average correlation to surface names that actually add uncorrelated exposure.
Regime-shift detection
When correlations converge to 1 across every timeframe, that's a risk-off signal. GroupiFi surfaces that pattern visually instead of hiding it in a heatmap.
Sector cluster analysis
Auto-cluster a basket into correlation groups. Useful for confirming a thematic thesis or unwinding a crowded trade.
No spreadsheets
Enter tickers, hit run. Results are live, sortable, and shareable via URL.
Free during beta
Basic correlation groups are free. Pro unlocks per-block AND/OR logic, parenthesized groups, and international tickers.
Frequently asked.
What correlation method does GroupiFi use?
Pearson correlation on log returns, computed rolling over each of the seven windows. Sample sizes are shown per window so you can trust the number and spot which timeframes have the strongest signal.
Where does the price data come from?
Live quotes stream from Alpaca's IEX feed the moment the market opens. Historical bars come from Yahoo Finance, adjusted for splits and dividends and cached in Supabase so every calculation stays fast and consistent.
How many symbols can I put in one group?
Free accounts get up to 15 tickers per group — enough to cover a diversified equity book. Pro adds side-by-side sector comparison across 5 baskets so you can see how the S&P sectors relate to your holdings at a glance.
Which markets does GroupiFi cover?
US equities and ETFs today, with international tickers (LSE, TSX, HKEX) shipping to Pro next. Every US ticker on the major exchanges is fair game — from mega-caps to small caps to sector ETFs.
Can I share or export a matrix?
Yes — every run has its own shareable URL, so you can send a live matrix straight to a teammate. Pro adds one-click CSV export of the underlying correlation values.
