this would work equally well without the head-check, e.g.: Position[{0.,-1,5,-5.3},_?Negative]. That is probably just relevant for those cases where your entries do not all have the same head but I often use it without checking for the head, the typical test function would return false for non-matching entries anyway, cf.: OddQ["a"]
