Last updated July 2026
Short answer
E*Trade Core Portfolios and Fidelity Go 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. Fidelity Go is hands-off automated investing (robo-advisors) (automates a fidelity flex fund portfolio), best for small balances, where it is free. Neither is universally better: pick E*Trade Core Portfolios if you want e*trade customers wanting a managed portfolio alongside self-directed trading, Fidelity Go if you want small balances, where it is free.

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 Fidelity Go?
Fidelity's automated service, free below a stated balance and built from zero-expense-ratio Fidelity Flex funds. Best for people starting out.
How it works: A questionnaire sets the allocation, and Fidelity invests it in its own Flex mutual funds, which carry no expense ratio because Fidelity earns the advisory fee instead. Below a stated balance there is no advisory fee at all, which makes it one of the genuinely free ways to get a managed portfolio; above it, a flat percentage applies.
In practice, Fidelity Go’s AI automates a fidelity flex fund portfolio. It falls under hands-off automated investing (robo-advisors), which makes it best suited to small balances, where it is free. On connecting an account it is “No (holds your money at Fidelity)”, and on execution it is “Automated”. It is priced as free under a stated balance, then a flat percentage (verify current).
One honest limitation: No tax-loss harvesting, which removes the strongest argument for a managed taxable account.
E*Trade Core Portfolios vs Fidelity Go: 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 Fidelity Go on small balances, where it is free (automates a fidelity flex fund portfolio). On broker connection they differ too: E*Trade Core Portfolios is “No (holds your money at E*Trade)” versus Fidelity Go at “No (holds your money at Fidelity)”. 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 Fidelity Go: 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
Fidelity Go
Where it is strong
- Genuinely free below the stated balance threshold, with no underlying fund expenses
- Zero-expense-ratio Flex funds mean the advisory fee is the whole cost, which is unusually easy to compare
- Coaching calls are included above a higher balance tier
What to watch out for
- No tax-loss harvesting, so the main reason to pay for a managed taxable account is absent
- Flex funds are Fidelity-only and not portable, so leaving means selling
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.
- Fidelity Go: manages a separate account it holds. Fidelity Go 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 Fidelity Go.
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 Fidelity Go: 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 Fidelity Go if you want small balances, where it is free. Its AI automates a fidelity flex fund portfolio, it is priced as free under a stated balance, then a flat percentage (verify current), and it fits hands-off automated investing (robo-advisors). It is built for someone with a smaller balance who wants automation at no cost and holds it in a retirement account where harvesting would not apply anyway. Keep in mind that no tax-loss harvesting, which removes the strongest argument for a managed taxable account.
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 Fidelity Go: 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 Fidelity Go is priced as free under a stated balance, then a flat 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.
