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.

Where it sits among rivals

Fennel sits at 1 of 213 for minimum deposit and 1 of 161 for stock trade fees, the strongest pair of positions in the comparison. The account fee trails at 112 of 138, so the low cost case rests on entry and trading rather than the account charge.
