It looks like y contains unique values. In that case replace

>         x.append(y.index(item))

with 
      x = list(range(len(x)))

or use a single loop

      for index, (num1, num2) in enumerate(pairwise(serie)):
         x.append(index)
         y.append( num2 / num1)

There should be only one loop; use if ... to avoid the IndexError

for i, num in enumerate(serie):
    if i < len(serie)-1:
       x.append(serie[i + 1]/ num)
       y.append(i)

or clip the list:

for i, num in enumerate(serie[:-1]):
    x.append(serie[i + 1]/ num)
    y.append(i)

But I would definitely recommend pairwise().
