1. What makes MarketPlays different?
Unlike traditional investment platforms, we don't follow experts or fund managers. We crowdsource real user data to create diversified portfolios, anchored by professional ETF allocations.
2. How does the 60/40 hybrid model work?
Each Hub combines two sources: 60% comes from aggregated holdings of real investors who've connected their brokerage accounts, and 40% comes from professional ETF allocations. This gives you the best of both worlds: the trend-spotting power of retail investors with the disciplined strategy of institutional managers.
3. Why should I trust what retail investors hold?
You're not trusting any individual. You're trusting the aggregate signal from thousands of investors, normalized so smaller accounts count equally. Research suggests aggregated retail positioning can provide useful momentum signals, especially when combined with institutional data. Plus, these are real positions backed by real money, not just opinions or tweets.
4. Why not just buy ETFs directly?
ETFs can't tell you when conviction is building, but we can. ETFs rebalance quarterly; Hub weights shift with real-time positioning. You get the strategic allocation of ETFs plus the momentum signal of what thousands of investors are buying right now.
5. What is the AI Researcher?
Our AI Researcher instantly analyzes any stock and breaks it down into 12 comprehensive sections: what the company does, revenue breakdown, competitors, risks, strengths, weaknesses, and more. It's like having a professional analyst explain any stock to you in 60 seconds. 100% free to use.
6. Is my brokerage account supported?
We support most major brokerages. We will announce the full list once we are closer to launching this feature.
7. How is my portfolio data used?
Your data is private and encrypted. We only aggregate holdings anonymously to build investment hubs. No personal data is shared.
8. Can I customize my portfolio while following a hub?
Yes! You're not locked into any hub's allocation. You can adjust weights, remove stocks, or add your own selections while still benefiting from community-driven diversification.
9. How does MarketPlays ensure diversification?
Our investment hubs are built using real retail investor portfolios, combined with professional ETF allocations. Instead of relying on a single person's stock picks, we aggregate holdings from thousands of users to create naturally diversified portfolios in different sectors.
10. Is MarketPlays a brokerage?
No, MarketPlays doesn't replace your brokerage. Instead, it integrates with your existing brokerage accounts, providing a unified portfolio view and the ability to invest in crowdsourced portfolios.
11. Can I use MarketPlays if I'm a beginner?
Absolutely! MarketPlays makes investing accessible by showing you what stocks other retail investors are holding, giving you a solid starting point without the complexity of stock picking.
12. What happens if my brokerage isn't supported?
We're constantly adding support for more brokerages. If yours isn't available yet, you can still use MarketPlays to explore investment hubs and track market trends while we expand our integrations.
13. Does MarketPlays charge fees?
MarketPlays' social features are completely free. You can join discussions, explore investment hubs, and research symbols without any cost.
To connect your brokerage accounts and sync your portfolio, a $9.99/month subscription is required. This allows us to provide secure brokerage integration, real-time portfolio tracking, and investment hub syncing.
