Stock Portfolios Using
ETF & Crowdsourced Data

We blend crowd holdings with ETF holdings. The default split is 60/40, and you can adjust it.
100% free to browse and track. Pro $9.99/month for unlimited trades, instant blend control, and more.
How We Build Stock Portfolios
We pull stock holdings from ETFs and real investor accounts, then blend them by industry.
ETF Holdings (default 40%)
We look at what stocks top ETFs hold for each industry. These picks come from professional research teams with regulatory oversight.
Crowd Holdings (default 60%)
We aggregate what stocks real investors hold, synced from their brokerage accounts. See what thousands of verified investors actually own.
Blended by Industry
We combine both sources into industry-focused portfolios: AI, Semiconductors, Biotech, Cybersecurity, and more. Updated as holdings change.
The Crowd + ETF Blend
The default split is 60% crowd / 40% ETF. You can adjust it to fit your style. Free users get one change per month, applied at the next recalculation. Pro unlocks instant updates.

| ETFQQQ | 15% |

| ETFARKK | 10% |
| RetailNVDA | 20% |

Yes. Browsing portfolios, seeing holdings, tracking performance, and making up to 2 trades per month is 100% free. Pro ($9.99/month) unlocks unlimited trades, instant blend control, all 350+ themes, and a unified view of your brokerage positions.
What is the 60/40 blend?
By default, 60% of the portfolio comes from what real investors hold, and 40% comes from ETF holdings. This is the starting point, not a fixed rule. You can adjust it to weight crowd or ETF data more heavily based on your preference.
Which ETFs do you pull data from?
We use relevant ETFs for each industry. AI portfolios pull from QQQ, SMH, SOXX holdings. Biotech pulls from XBI, IBB. We extract the stocks they hold, not the ETFs themselves.
Can I use any broker?
Yes. We integrate with 8 major brokerages: Alpaca, Webull, E*TRADE, Schwab, TastyTrade, TradeStation, Tradier, and Interactive Brokers.
