If you liked them at one price why not like them even more at a cheaper price. Till the fundamentals of the company change and deteriorate from bad management and bad deals price month to month, quarter to quarter, even somewhat year to year is sorta irellevant and short term thinking. That's fluctuations of the market overall not the company. And the market will always go up then down then back up then down. So plan for the inevitable down to buy more good companies but don't ever think it won't continue up or come back up. Stay invested.
