With the only exception of tax treatment for different holding periods or year of sale. If you’re a few days away from getting long-term treatment on a large gain, you’re not in exactly the same position as someone buying today and could easily have a different risk-adjusted return on holding shares you think are over-valued for a few more trading days.

Less common is if you have a long-term loss (in-year or carry-forward) that will be used to offset a short-term gain, but you have a long-term unrealized gain. In that case, you would consider holding and realizing the long-term gain in the subsequent year, allowing the (less valuable) long-term loss to offset the (more expensive) short-term gain.
