The Anatomy of Pump n' Dump Stock Spamming

giorgiofr writes "Laura Frieder and Jonathan Zittrain have analyzed pump n' dump spam activity in their paper 'Spam Works: Evidence from Stock Touts and Corresponding Market Activity'. Unbelievably, it appears that spammers are able to achieve a 5% gain on pumped stock before dumping it, along with a dramatic increase in transaction volume of the stock. From the synopsis: ' We suggest that the effectiveness of spammed stock touting calls into question prevailing models of securities regulation that rely principally on the proper labeling of information and disclosure of conflicts of interest to protect consumers, and we propose several regulatory and industry interventions. Based on a large sample of touted stocks listed on the Pink Sheets quotation system, we find that stocks experience a significantly positive return on days prior to heavy touting via spam. Volume of trading responds positively and significantly to heavy touting.'"

  1. Invest in spam-filter companies ;) by Reverse+Gear · · Score: 5, Insightful

    I bet many or maybe even most of the people who start buying the stocks being spammed, buy them in the expectancy that the spamming will make the value of that stock rise.
    Thereby they reinforce this strange mafia way of making money and worst of all they make sure that loads of spam will keep on putting even more pressure on the internet.

    The only sensible conclusion I am able to draw from this is that it probably will pay of to invest in the spam-filter companies ;)

    Really, this should be the easiest to crack. Someone has to take the money. Or some company which then turns it over to some person. The SEC should be busting these left and right.

      Except, you've missed the point on the very reason these scams do make money - Because people buy these stocks realizing them as pump-n-dump scams, hoping to trade out in time.

      Pretty easy, actually...

      1) Get stock spam
      2) See if the price has gone up in the past week. If so, forget it. If not, continue o step 3
      3) Buy a few thousand shares
      4) Watch the price carefully.
      5) The second it starts going up, sell sell sell! Don't try to time it for best profit, dump ASAP.
      6) Profit!


      So, by "following the money", they'd potentially catch honest traders as well as those running the scam.

      Mutual fund managers are almost never empowered to trade the "pinks". Plus why would they bother risking their $$$$$ jobs for a 5% profit? Part of the reason they can't/don't is that you just can't put large amounts of $ to work in these stocks. Even if they truly loved some penny stock and thought it would be the next microsoft - you can't invest even as little $10M in a company with $50M market without totally distorting the market - easier to just do a buy out the company of you like it that much.

      In theory you could write a few lines of java/lisp/perl into your favorite automated trading platform and seek out the patterns of the spammers taking their position before they start pumping. That is, if they traded on some "real" exchange you could. In the "pinks sheets" there are no market makers, frequently no level 2 quotes, etc. Not enough data to easily find the patterns. As others have pointed out, this is also what makes it hard to prosecute the pumpers, they data trail is just too thin.

    The problem with that, is that there's millions of middle-low class citizens in the world that are fully aware they will never have the things of thier dreams without taking a chance now & then.

    Spam like that is successfull for the same reasons lotterys are successfull.
    Not because people don't know, but because they're prone to greed.
