Pros and cons
Composer
Pros
- The regulators are SEC, FINRA and SIPC, and investor protection is SIPC up to USD 500,000.
- Account types cover ira, roth ira and corporate, which suits ordinary retirement savers as well as company money.
- A mobile app (mobile app) lets you check the account away from a desk.
Cons
- Trading stops at stocks and etfs, so forex, CFDs and crypto sit outside the platform.
- The $50 minimum deposit is above the $0 entry point at CFI and the $5 at Vantage.
- Retail accounts on this site lose money at 70.15% in the median case and 72.03% in the stocks ranking, so a broker-run portfolio still carries real downside.
Fennel
Pros
- Stock trades cost $0, so entry costs sit at the floor of the market.
- A minimum deposit of $0 lets an account start from a small sum.
- Regulators listed are FINRA and SIPC, with investor protection at SIPC up to USD 500,000.
Cons
- The account types listed are ira, so there is no taxable brokerage account on offer.
- Markets stop at stocks and etfs, where CFI lists stocks, etfs and forex.
- There is no live chat, since support runs on email, phone and help centre.
Who each suits
Composer
Who it suits
- Retirement savers who want a broker-run portfolio of stocks and etfs and accept a $50 starting amount.
- Cost-first readers, who get an account fee of $0 and a stock trade fee of $0.
- People happy with US equities and ETFs rather than a long market list; eToro offers stocks, etfs and forex instead.
Who should look elsewhere
- Anyone after forex, CFDs or crypto on the same account, since Composer trades stocks and etfs, while eToro covers stocks, etfs and forex.
- Savers who need to start below $50: CFI opens at $0 and Vantage at $5.
- Investors who want a taxable general account, as the account types are ira, roth ira and corporate and centre on retirement and corporate money.
Fennel
Who it suits
- US investors opening or holding an IRA, since the account types are ira.
- Investors trading shares and exchange traded funds from a phone, since the platforms are mobile app and web.
- Readers starting with a small amount, since the minimum deposit is $0.
Who should look elsewhere
- Not for CFI users who want forex, contracts for difference or crypto, since CFI lists stocks, etfs and forex.
- Not for readers who would rather hold no account fee, as the eToro account fee is $0 against Fennel's $4.99.
- Not for Vantage users who want a stated starting level, since Vantage asks for $5 and Fennel asks for $0.
