It's not the evil eye, its the fact that joys are usually short lived. Correlating them to an event is a typically human way of making sense of the events.
Our constant state of apprehension has been useful for us as a specie in an evolutionary perspective. At one time the senses of our ancestors had to be at high alert for reasons external to them. Today, anyone equipped with what we consider to be the basic needs of life may testify that as we  start to feel safe , the source of our attention moves from the external to an internal locus . We are quick to celebrate and quicker perhaps, to mourn.The transient state of emotions we feel and the ups and downs that we experience reflect nothing but the true nature of everything that is there : temporariness. Perhaps nothing more should be read into it.
Also, under such circumstances, care might be employed in gloating too soon over a victory,  or celebrating your happiness publicly . Tomorrow as the tide turns, you may be left alone with people who find it hard to believe the account of your misfortune because you had them convinced otherwise. And there are few things worse than proving your misery to win understanding.
