Hey hunters! JJ here 👋 and I’m very excited to introduce Double today! Double let’s anyone design and invest in their own Stock Index. 🛠️ How Double Works --------------------------------------------------------- - 🧠 Choose Your Strategies: Start by selecting one or more of our 20+ pre-built direct indexed strategies, focusing on broad markets like the S&P 500, specific sectors, industries, themes, or even custom groupings (think: all publicly traded YC companies) - ⚙️ Customize, Combine and Make Your Own: We let you easily deeply customize your strategies, tilting towards or against your hunches on a stock or sector level. You can also create your own baskets using our stock and ETF screener. - 🤖 Tax-Optimized Automation: Sit back as Double handles the complexities of trading, employing tax-aware rebalancing and tax-loss harvesting (if eligible) with the aim of maximizing your after-tax returns. We continuously monitor your portfolio, considering factors like market drift, tax implications, and transaction costs before making any trades. - 🔀 Flexible Portfolio Adjustments: Easily modify your investments all at once or gradually over time. Dollar-cost averaging is built in, allowing you to invest consistently regardless of market conditions and reduce timing risks. 💡 Common Use Cases --------------------------------------------------------- - 💼 Big Tech Employee Seeking Diversification: If you work at a major tech company, use direct indexing to remove your employer's stock from your portfolio and even reduce the overall weighting of the tech sector. - ⏸️ Temporary Risk Reduction: Easily schedule recurring portfolio changes to shift your investments into a less volatile strategy for a specific period, like the next six months. - 🎯 Individual Stock Picks: Believe in the continued success of ZYN or have a basket of favorite fast-casual restaurants? Allocate a portion of your portfolio to a custom basket of stocks. Our built-in backtesting within the stock screener even lets you see how your basket would have performed historically. 💰 Cost-Effective Investing --------------------------------------------------------- - 💵 Worried about high fees? We charge a nominal $1 per month, and your first six months on the platform are completely free! 🚀 Our Motivation --------------------------------------------------------- - 🏦 Traditionally, sophisticated financial tools like direct indexing and tax-loss harvesting were only accessible through high-priced financial advisors. While DIY options existed, they often involved tedious spreadsheets and manual trade execution. Double was created to democratize access to advanced portfolio optimization tools, making investing both powerful and user-friendly. 💬 We're excited to hear your thoughts and welcome any questions you may have!

this is the investment app i've always dreamed about! One question though - for people who work in industries where they have to report individual stock trades but not ETF trades (for regulatory reasons), is it still possible to use Double?

@nsbradford So our account is treated as discretionary, meaning we have the discretion to make trades on your behalf. I believe this is usually the distinction that firms relay on for whether things need to be cleared before trading or not. Wealthfront for example, despite holding individual stocks in their direct index portfolio, in my experience has usually been allowed by companies without the need to report every trade. But anyone in this scenario should check with their compliance team.

Never invested in stocks/indexes before, but just being able to play within your interface and see potential backtested annual returns makes it a ton of fun. Amazing product!

Congrats on the launch! It's a handy tool to manage the stock. It contains all the essential functions when one analyzes their stock: comparison between different stocks throughout different periods, customizing allocation, and insurance of security....Each function is easily accessible, for the page is designed as clearly and straightforwardly as possible. And this is awesome!

This is a pretty cool tool for those who know what they are doing, but also for the average joe who wants to customize. I think the big use case is if I can replicate an ETF and get it to auto balance, then I can save on the fees. Even 0.09% adds up for SPY. This is pretty cool tool! I love how you are honest with your business model - you want to make money like RobinHood and those with 0% commission fees. It's important for people to know. Congrats on the launch @jj_maxwell and team! Please let us know when you are in Canada here :)
