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. Announce to everyone that you own UNIX. Make sure to grab a lot of media attention.
    2. Sue IBM for stealing your code. Make sure to grab a lot of media attention.
    3. Sell off stocks after everyone else buys, but before anyone realizes that you don't actually have any evidence that IBM stole code.

    Much like cigarette tax money goes to health education, wouldn't it be great if lottery profits were required to go to statistics and finance education?

    That said, all the people I know who p[l]ay the lottery claim to do it because the realization of the possibility of great wealth is entertaining enough that it is worth the expense, even if they never win.

    Don't get left in the dust on this one. We are expecting big news from this infotech player. Undervalued now; but expect it to skyrocket on Monday on a new press release. Monday may be your last chance to get a great price on this undervalued st0ck.

    I see two obvious solutions:

    1) Do not allow morons access to the Internet
    2) Do not allow morons to trade stocks

    I vote for the number 1 as it will solve a couple of other problems as well.
