How We Build Stock Portfolios
We pull stock holdings from ETFs and real investor accounts, then blend them by industry.
ETF Holdings (40%)
We look at what stocks top ETFs hold for each industry. These picks come from professional research teams with regulatory oversight.
Crowd Holdings (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.
