We show that for many values of the multiplier, the cycles in the unit disk of the corresponding monic quadratic polynomial are \"optimal\" in the following sense: They minimize the distance to the origin among cycles of the same minimal period of normalized germs having an irrationally indifferent fixed point at the origin with the same multiplier. We also give examples of multipliers for which the corresponding quadratic polynomial does not have optimal cycles.
