"Socialism" implies more governmental control, and "nationalism" refers to being dedicated to the Nation/People/Race/Folk. So capitalism may be permitted, but it must be subject to governmental regulations calculated to keep capitalism in service to the People, and to prevent tyrannical monopolies and abuse of corporate power.
Much like fire: it is a good servant but a terrible master. Capitalism, like all things, can only be permitted so long as it serves the people, and it must never be permitted to rule the people.
Is a fireman opposed to fire? have you never seen a fireman rescue people from a burning house and put out the conflagration - then, after his work is complete, pause to light a cigarette? National-Socialism is opposed to the mastery of Man by capitalism. But capitalism may live on as a humble servant.
