Does keyword order matter in a domain name

Does the keyword order matter in a domain name? I know that it's less brandable, but lets say I'm only focusing on the ranking potentials.
And how does dashes affect the ranking of a domain name - compared to one without dashes?

If I were to chose between these two domains:

lose-weight-fast.com
weightlose.com

Which one would be easier to rank?

keyword order doesn't matter at all.In my opinion , second one will be easier to rank (quicker )
