Dealing with calls gone wrong?

I'd imagine experienced sell-side ER analysts have had to go through the experience of a stock going the opposite direction of your call multiple times. As a relatively new analyst going through it for the first time, it's a bit nerve wracking seeing a stock you pitched a Buy keep dropping. How do you guys typically deal with this? Both in terms of work (i.e. do you intensify/lower client interactions? do you reverse your call?) and in terms of your own thoughts (i.e. how do you move on from the call?).

Admittedly, it's a LOT SMALLER of a problem for us on the sell-side because we aren't actually putting in the $$.

Also, it'd probably be important to differentiate between calls gone wrong because of your fundamental thesis being wrong or calls gone wrong because of unpredictable externalities. I'm more on the second boat right now, but the question applies to both.
