I exited NUH this afternoon having sold this morning and buying again on the pullback. Not sure how these big tech expos work in the US. I looked at the exhibitor listing and there are 137 pages. That equates to more than 4000 booths. There are some big names like Amazon, Samsung and Facebook and others which may well operate out of a shed in someone's backyard for all I know.

I'll watch the movement tomorrow with interest.
