For the bragging rights.

It was already about to be delisted and I think it was sub $1/share. So I looked up how much I'd need to own to match the largest individual investor, and decided.

I could have invested the paltry amount (I actually cannot remember how much, but it was < $10k in my IRA) in something worth while, or... burn it all to own more more than any other individual investor at the time that I did it.

I only held for a couple of days, before selling it at a ~70% loss - or vanguard liquidating when it delisted - I cannot remember now.

But it was a fun ride and brag I got to have. People at the office cheered for me. People in my house berated me.

Not the guy you asked, but he just listed a half-dozen or so things he probably expected them to expand into that were promising/could have worked out, so I'm guessing he invested hoping they'd do those things, and was pissed when they didn't.
