calculation and analysis: need help with Limit (DirectedInfinity)


I tried to calculate the following limit:

Limit(Series(
  1/(1/x^2) (Sin(y x)/(x^4))^2 - Sin(y x)/y(x^3) + 1/x^2, {x, 0, 5}), 
 x -> 0, Assumptions -> {y > 0})

The exit :

DirectedInfinity(Sign(y)^2)

What does this mean? Is there any solution?
Thanks in advance.
