It might be an interesting failure scenario for algorithmic trading. Almost like misspelled domain names and ad networks.

I'm curious to know what happens after they halt trading. What's the outcome for those with outstanding shares? I would assume either the spread would get ridiculously wide or the sell orders never be fulfilled?

  Trading halts trading, not ownership; Assuming the trades themselves are not cancelled, he who holds the bag owns the bag.

    Trades have been reversed before, though.

> It might be an interesting failure scenario for algorithmic trading. It's not how auto trading works. Traded instrument ranges are preset before the algo is started. I've never heard of an algo that tries to pick stocks to trade dynamically based on a name, it would be astoundingly risky.

  RIC codes are the industry standard security identifier. Name doesn't play apart, must be some truely idiotic manual investors.

  > It's not how auto trading works. That's OK. It doesn't have to exist for it to be interesting to me. Think of it more like an interesting extrapolation of a scifi story, if you want. HFT advantages become slim enough to warrant dynamic instrument selection based on twitter sentiment analysis. So, you get bad algorithms following imperfect people, who execute millions of trades to fast to watch. And, someone trying to take advantage of that would act like a domain squatter, taking stake in a penny stock, predicting the next misspelling and correction.

  What does the name have to do with anything? A few dozen people screw up and the bots see a stock go from worthless to hot in a short period of time and jump on board.

That's a pity. I think people should be able to have their lulz, or learn a lesson the hard way, as the case may be.
