Parametric, a part of Morgan Stanley Investment Management, recently reported that its proprietary Radius technology platform drove more than 19% growth in assets and accounts during its first year. The update, shared in a Feb. 18, 2026 press release from Morgan Stanley Investment Management, also highlighted improvements in data analysis and trading capacity.
For everyday investors, this news is significant because platforms like Radius automate tools that can improve after-tax results. These features, including tax-loss harvesting and direct indexing, are becoming more available across the Morgan Stanley ecosystem.
This network includes E*TRADE and similar brokerage platforms used by retail investors.
Key Takeaways
- Parametric’s Radius platform saw 19% growth in its first year, signaling high demand for tech-driven portfolio customization.
- The system is designed to manage hundreds of thousands of portfolios simultaneously with advanced reporting for pre-tax and after-tax returns.
- Higher trading volumes on the platform help capture tax-loss harvesting opportunities, which is especially useful in volatile markets.
- While Radius is not yet a direct feature in the E*TRADE retail app, it represents the core technology Morgan Stanley is building for future wealth management.
What exactly did Parametric announce about Radius?
Parametric launched Radius in January 2025 as a cloud-based platform to support multi-asset portfolio management. In its first year, the firm saw significant growth in assets and accounts, which it attributes to the platform's ability to handle complex data and high trading volumes.
While these points may seem technical, they are closely linked to investor performance. Better data and scalable infrastructure allow for more consistent tax-aware strategies.
This is particularly useful for direct indexing and systematic tax-loss harvesting within taxable brokerage accounts.

How does Radius fit into Morgan Stanley and E*TRADE’s ecosystem?
Radius is part of the broader technology stack at Morgan Stanley that supports advisory and wealth management. The press release does not confirm a direct link to the E*TRADE mobile app today.
However, it suggests that these advanced optimization tools may soon power the managed accounts and advisory programs that E*TRADE customers use.
Why does “tax efficiency” matter so much to individual investors?
Taxes often create a gap between what your investments earn and what you actually keep. This is a major factor in taxable brokerage accounts where capital gains, dividends, and interest income can trigger tax bills.
Understanding these impacts is essential, especially when working with a financial planner or advisor.
Radius serves as the infrastructure that makes tax management more systematic. According to the press release, the platform provides reporting that illustrates both pre-tax and after-tax returns.
This helps investors see exactly how much taxes are impacting their overall performance.
How does Radius potentially improve tax-loss harvesting?
Tax-loss harvesting involves selling an investment at a loss to offset capital gains and reduce your tax bill. This strategy allows you to maintain market exposure while following IRS rules, such as the wash sale rule.
Radius brings scale and automation to this process. The platform can support high trading volumes to capture these opportunities across thousands of portfolios at once.
This systematic approach is a key part of modern automated investing. Capturing these losses is especially important during market swings.
Knowing how to invest in various market conditions is a vital skill for long-term success. An automated system can scan holdings and trade more consistently than a manual process.
Is Radius actually part of E*TRADE’s investing experience today?
Based on current reports, Radius is not yet a named feature inside the E*TRADE retail platform. While Parametric and E*TRADE share a parent company, the technology is currently used primarily on the institutional and advisory side.
However, technology investments at Morgan Stanley often flow down to retail clients over time. This means E*TRADE users may eventually see these tax-managed solutions in their managed portfolios.
In a separate move, Morgan Stanley plans to introduce cryptocurrency trading for E*TRADE customers in 2026. This service will initially support Bitcoin, Ethereum, and Solana, according to a BeInCrypto report.
Why would higher trading volume be a good thing for investors?
More trading is not always better, as frequent activity can increase costs and taxes. However, the Radius announcement frames higher volume as a tool for precision.
In tax-loss harvesting, trading is the mechanism used to capture a loss the moment it occurs. A platform that can place these trades efficiently across many accounts is better positioned to deliver tax savings.
For consumers, more trading is only beneficial if it follows a specific set of rules. It must be systematic, cost-aware, and strictly focused on tax benefits while avoiding wash sales.
How does customizable indexing help everyday investors?
Direct indexing allows you to own a basket of individual stocks that track an index rather than buying a single fund. This provides more control, allowing you to customize your holdings and harvest losses on individual stocks.
Radius supports this customization through its modern data architecture. If these features reach retail platforms, they could offer more personalized portfolios that are hard to replicate with standard index ETFs.
What fees or account minimums should investors expect?
The current announcements do not list specific fees or minimum balance requirements for Radius-powered accounts. This is an important detail for consumers to watch.
Strategies like direct indexing often require managed accounts, which may have higher fees than self-directed trading. Before joining a tax-managed program, investors should review total costs and how the broker measures after-tax success.
How should investors compare E*TRADE’s tax tools with Fidelity or Schwab?
There is currently not enough data to provide a direct feature comparison between E*TRADE and competitors like Fidelity or Charles Schwab regarding Radius. However, consumers can still compare basic tax tools across these platforms.
Investors should look for easy-to-use tax-lot tools and automated tax management in robo-advisors. It is also helpful to see if the broker provides clear reporting on after-tax performance.
What does Parametric’s Radius mean for tax-efficient investing going forward?
Radius highlights a shift toward using automation and data to simplify tax-aware investing. As more firms adopt these platforms, features like automated harvesting and direct indexing may become standard for a wider range of investors.
This technology makes sophisticated tax strategies more accessible through traditional brokerage and advisory relationships.
The Bottom Line
The Radius platform is a backend technology story that has real benefits for individual investors. Better data and automated trading can improve after-tax outcomes for those using Morgan Stanley's infrastructure.
For E*TRADE customers, the news signals a move toward more sophisticated, automated, and tax-efficient investing tools in the near future.
