Question formulation sentence structure

I wish to improve this sentence, which sounds bad to me but maybe acceptable:

Are traditional investors at disadvantaged against high-frequency traders?

should I say:

  • Are traditional investors at disadvantaged versus high-frequency traders?
  • Are traditional investors at disadvantaged relatively to high-frequency traders?

any other suggestions?


All three sentences that you've posted are ungrammatical. I would write

Are traditional investors at a disadvantage, relative to high-frequency traders?
