E*Trade Core Portfolios vs SigFig: Which Is Better in 2026?
Last updated July 2026
Short answer
E*Trade Core Portfolios and SigFig are often compared, but they are built for different jobs. E*Trade Core Portfolios is hands-off automated investing (robo-advisors) (automates a diversified etf portfolio), best for e*trade customers wanting a managed portfolio alongside self-directed trading. SigFig is hands-off automated investing (robo-advisors) (automates a portfolio in accounts you already hold), best for automation that manages your existing schwab or fidelity account. Neither is universally better: pick E*Trade Core Portfolios if you want e*trade customers wanting a managed portfolio alongside self-directed trading, SigFig if you want automation that manages your existing schwab or fidelity account.
Both E*Trade Core Portfolios and SigFig get grouped under “AI investing tools,” which is why people compare them, but they sit in different categories and answer to different needs. Below is a balanced, 2026 look at what each one does, whether it reads the brokerage you already use, how each is priced, and who each fits, so you can tell which job you are actually hiring a tool for. Where relevant, we note where Walnut sits in its own category: chat-driven management of your own broker. Walnut is not an investment adviser.

What is E*Trade Core Portfolios?
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 falls under hands-off automated investing (robo-advisors), which makes it best suited to e*trade customers wanting a managed portfolio alongside self-directed trading. On connecting an account it is “No (holds your money at E*Trade)”, and on execution it is “Automated”. It is priced as percentage of assets (verify current).
One honest limitation: A conventional service whose main advantage is sitting next to an E*Trade brokerage account.
What is SigFig?
An automated investing service that manages accounts held at your existing broker rather than requiring you to move money.
How it works: Rather than opening a new account, you link an existing brokerage account at a supported custodian and SigFig manages it in place, rebalancing and running tax-efficient strategies. Below a stated balance the management is free. This structure is unusual: nearly every competitor requires custody of your assets.
In practice, SigFig’s AI automates a portfolio in accounts you already hold. It falls under hands-off automated investing (robo-advisors), which makes it best suited to automation that manages your existing schwab or fidelity account. On connecting an account it is “Yes, it manages accounts held at supported brokers”, and on execution it is “Automated”. It is priced as free under a stated balance, then a percentage (verify current).
One honest limitation: Supported custodians are limited, so it only works if your account is already at one of them.
E*Trade Core Portfolios vs SigFig: how they actually differ
The core difference is category. E*Trade Core Portfolios focuses on e*trade customers wanting a managed portfolio alongside self-directed trading (automates a diversified etf portfolio), and SigFig on automation that manages your existing schwab or fidelity account (automates a portfolio in accounts you already hold). On broker connection they differ too: E*Trade Core Portfolios is “No (holds your money at E*Trade)” versus SigFig at “Yes, it manages accounts held at supported brokers”. That shapes everything downstream: how personal the answers are, where trades settle, and how much control you keep over individual positions.
E*Trade Core Portfolios vs SigFig: strengths and trade-offs
Every tool gives something up for what it does well. Here is the honest give-and-take on each, so you can weigh the specific strengths against the limitations that come with them rather than judging on the headline category alone.
E*Trade Core Portfolios
Where it is strong
- Managed and self-directed accounts side by side under one login
- Portfolio variants including socially responsible options
- Backed by Morgan Stanley following the acquisition
What to watch out for
- Priced at the middle of the market with no distinguishing feature
- A minimum applies to open the managed portfolio
SigFig
Where it is strong
- Manages the account you already have rather than requiring a transfer
- Free below a stated balance
- Avoids the tax consequences of liquidating to move to a new provider
What to watch out for
- Only works with a short list of supported custodians
- Smaller and less prominent than the large robo-advisors, so check the current state of the service
The key divider: does it read your real holdings?
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.
- SigFig: manages a separate account it holds. SigFig 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 SigFig.
On this specific question the two land on the same side, so the deciding factors between them are elsewhere: category, cost, and who each is built for. 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.
E*Trade Core Portfolios vs SigFig: which should you choose?
There is no universal winner here; the right pick depends on the job you are hiring the tool for. Match the category to your intent rather than chasing a single “best.”
- 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, it is priced as percentage of assets (verify current), and it fits hands-off automated investing (robo-advisors). It is built for an existing E*Trade customer who wants part of the money handled automatically and part self-directed. Keep in mind that a conventional service whose main advantage is sitting next to an e*trade brokerage account.
- Choose SigFig if you want automation that manages your existing schwab or fidelity account. Its AI automates a portfolio in accounts you already hold, it is priced as free under a stated balance, then a percentage (verify current), and it fits hands-off automated investing (robo-advisors). It is built for someone with an existing account at a supported broker who wants it managed without moving anything. Keep in mind that supported custodians are limited, so it only works if your account is already at one of them.
Because both sit in the same category, the choice comes down to the finer details above rather than a fundamental difference in approach.
E*Trade Core Portfolios vs SigFig: pricing and cost model
Cost is easy to misread when two tools charge in different shapes, so compare the model, not just the number. E*Trade Core Portfolios is priced as percentage of assets (verify current), while SigFig is priced as free under a stated balance, then a percentage (verify current). 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.
Pricing and tiers change often. Confirm the current numbers on each provider’s own site before you decide; the framing above is point-in-time.
Where Walnut fits
If neither quite fits, Walnut sits in a third category: chat-driven management of your own brokerage. It connects the brokerage you already use through SnapTrade, lets you analyze and manage it by talking through Claude or ChatGPT, build thematic portfolios around a thesis, and place trades you approve. Read-only by default. See Walnut vs E*Trade Core Portfolios and Walnut vs SigFig. Walnut is not an investment adviser.
