E*Trade Core Portfolios vs Magnifi: Which Is Better in 2026?

Prices checked October 2026. A price marked (Oct 2026) was read on the vendor's own pricing page; others are described without a number because we could not verify one.

E*Trade's automated investing service, offering managed ETF portfolios alongside its self-directed brokerage, now under Morgan Stanley.

How it works: A questionnaire sets a risk level and E*Trade invests in a diversified ETF portfolio with automatic rebalancing, including socially responsible and smart-beta variants. It sits alongside E*Trade's self-directed brokerage, so a managed portfolio and an account you trade yourself live under one login.

In practice, E*Trade Core Portfolios’s AI automates a diversified ETF portfolio. It is a robo-advisor (hands-off automated investing), best suited to e*Trade customers wanting a managed portfolio alongside self-directed trading. On connecting an account: no (holds your money at E*Trade). On execution: automated. Cost: 0.30%/yr, $500 minimum (Oct 2026).

One real limitation: A conventional service whose main advantage is sitting next to an E*Trade brokerage account.

A conversational AI investing assistant you can ask natural-language questions about funds and holdings, with account-connection features. Best for research and discovery in plain English.

How it works: Magnifi is built around a chat box: you ask plain-English questions like "what are low-cost clean-energy ETFs?" or "how diversified am I?" and it surfaces investments, side-by-side comparisons, and observations. You can link accounts so its answers reflect what you actually hold, and it points you toward funds and stocks to consider.

In practice, Magnifi’s AI conversational fund/stock research. It is an AI stock research and scoring tool, best suited to research and discovery in plain English. On connecting an account: partial. On execution: read / discovery. Cost: free plan; Premium is a paid subscription (as of October 2026).

One real limitation: Skews toward fund discovery; it is weaker at managing a concentrated stock portfolio.

Category comes first. E*Trade Core Portfolios focuses on e*Trade customers wanting a managed portfolio alongside self-directed trading (automates a diversified ETF portfolio), and Magnifi on research and discovery in plain English (conversational fund/stock research). On broker connection they differ too: E*Trade Core Portfolios is “No (holds your money at E*Trade)” versus Magnifi at “Partial”. That shapes everything downstream: how personal the answers are, where trades settle, and how much control you keep over individual positions.

Every tool gives something up for what it does well. Below is the give-and-take on each, so you can weigh the specific strengths against the limitations that come with them, beyond the headline category.

For AI investing tools, the distinction that matters most is whether the tool works from your actual, connected positions or reasons from something else: a separate account it manages for you, or the tickers and numbers you feed it. It decides how personal the answers can be, and where your money physically lives.

• E*Trade Core Portfolios: manages a separate account it holds. E*Trade Core Portfolios does not read the brokerage you already use. It opens and holds a new account, then invests the money you move into it, so its view is limited to what sits inside E*Trade Core Portfolios.
• Magnifi: partial account connection. Magnifi offers some account-connection features, but it leans toward research and discovery. It does not keep a full, continuous read of your real positions.

This is where they diverge most. One works from your real, connected account while the other does not, so if you want an assistant grounded in the exact positions you already hold, that gap is the thing to weigh first. This holdings-aware angle is the one Walnut is built around: it connects the brokerage you already use and reasons from your live positions, read-only by default, with any trades left for you to approve.

Each one wins a different job, so the answer depends on which job you need done.

• Choose E*Trade Core Portfolios if you want e*Trade customers wanting a managed portfolio alongside self-directed trading. Its AI automates a diversified ETF portfolio, and it costs 0.30%/yr, $500 minimum (Oct 2026). It is built for an existing E*Trade customer who wants part of the money handled automatically and part self-directed. Keep in mind: a conventional service whose main advantage is sitting next to an E*Trade brokerage account.
• Choose Magnifi if you want research and discovery in plain English. Its AI conversational fund/stock research, and it costs free plan; Premium is a paid subscription (as of October 2026). It is built for investors who want to research and discover funds by chatting in plain English. Keep in mind: skews toward fund discovery; it is weaker at managing a concentrated stock portfolio.
• Choose Walnut if you want a keep, trim or exit read on the stocks you already own, and placing the trades you approve. It is an AI investing app that connects the broker you already use, and it costs free; Walnut Plus $9.99/mo on the web; no fee on assets.

Because they sit in different categories, this is not strictly either-or: some investors use one for e*Trade customers wanting a managed portfolio alongside self-directed trading and the other for research and discovery in plain English, and watch for overlapping costs.

Cost is easy to misread when two tools charge in different shapes, so compare the model, not just the number. E*Trade Core Portfolios: 0.30%/yr, $500 minimum (Oct 2026). Magnifi: free plan; Premium is a paid subscription (as of October 2026). A percentage-of-assets fee scales with your balance, a flat subscription does not, and a “free” tier usually earns elsewhere (on cash, order flow, or premium upgrades), so the cheapest headline is not always the cheapest outcome for your situation.

Prices checked October 2026. Pricing and tiers change, so confirm the current numbers on each provider’s own site before you decide.

Walnut is an AI investing app, and it is the pick for a keep, trim or exit read on the stocks you already own, and placing the trades you approve (free; Walnut Plus $9.99/mo on the web; no fee on assets). It connects the brokerage you already use, read-only by default, gives each holding a keep, trim or exit read against the S&P 500, flags any position above a quarter of the portfolio, and places the trades you approve. You use it through its own assistant, or inside Claude or ChatGPT. See Walnut vs E*Trade Core Portfolios and Walnut vs Magnifi.
