Yes, it can definitely be the opposite. And product companies can have the hardest time if their target audience was the bubble companies or those that supported the bubble companies. This is also part of why I think a lot of things are different this time around, although we could still crash, but I personally feel it would be different.

Last time much of the entire market and product was new, e.g. web purchasing was barely in its infancy, companies were building up around that and the web wasn't an integral part of peoples lives, yet. Today, everything we do is around smart devices, the internet etc, so I don't think a collapse like we saw during the dot com boom/bust is likely. But that's just my opinion, could be totally wrong.
