It's just the ferrule moving. A dab of epoxy and slide it back down and you're good to go.

If epoxy does not reach the ferrule, they often will expand in hot weather and slip down. Apply some epoxy or superglue in the gap, heat it with a blowdryer, and slip it back in place. After the glue sets it should stay in place.

Me thinks its inferior glue/install. I'm not a fitter or pro. I think that there should be a little glue at the point its fits into the adapter.

Good questions for you fitters/pros. I want to learn, need an answer.... thanks

Just put a 10 mm open-end wrench around the shaft above the hosel and tap it back into position with a light weight hammer. I also put a portion of a soft towel/rag between the wrench and the shaft/hosel to protect from scratching.

This separation will likely continue to happen. It's a common issue if/when the epoxy lets loose inside the hosel. In general, most epoxy doesn't adhere that well to simple plastics such as the hosel is made from, as much as it does to a properly prepared graphite/composite shaft and club head coupling.

For a more lasting fix, albeit still questionable long-term, you can tap the hosel up further and clear of the head, clean/slightly sand the flanged area, add some epoxy and tap it back into position. Clean any excess epoxy on the shaft around the joint, wait 24 hours and keep you fingers crossed that you won't have to repair it again....until it lets go again. Depending on how well you prepared the joint for epoxy, this could be a day or years.

Yes, I've seen/had that happen a couple of times. Like Dale said, my was caused by the heat (left clubs in car for extended period). You can used some bonding glue or epoxy if you have some, if not a club repair shop can fix it (probably at no cause since all you need is a dab of epoxy and push it down).

Can you twist the clubhead? The clubhead might be leaving the shaft behind on some future swing.

This happened to a fairway that i had built with an aftermarket shaft. I took it back to the shop and they cleaned and re applied the epoxy and it's been solid ever since.

Has not happened to me, when my shafts installed by professional installers/Titleist and kept out of heat when not in use.
