Heh.. I've just noticed that Adam's old company (in real life) has an entry on the Neodaq:
Heh

Powlex, for those who don't know, was a real company that Adam ran before he made Neopets
Edit: I've also just noticed that the ticker symbol for Huberts Hot Dogs is HUW - the Welsh spelling of Hugh. Since there's no W in "Huberts Hot Dogs" (and no apostrophe either, naughty Neopets), I think we can assume that Adam decided on that symbol, to throw a little bit of Wales into the Neodaq
