SEC Halts Trading on Spam Driven Stocks

goombah99 writes "The SEC has taken action to halt transactions on spam-touted stocks. Presumably this opens an opportunity for denial of service attacks on stocks. However, to be effective spam generally must target penny stocks with historically low volumes and thus the actual capitalized market impact or effect on the companies for a temporary shutdown can be expected to be negligible and transient. One example was given of a touted apparel stock jumping from 6 cents to 45 cents over a period of days before settling down to ten cents a share and near 65,000 or about $6500 in transactions (an eighth of the peak share volume, and a 50th of the peak transaction value). In other words, the market distortion of a brief shutdown, even if it were a DOS attack, would be massively less than the integrated spam surge. The thing I found surprising was that for this to be an effective measure with human oversight then the number of such events must be relatively small in number. From the amount of spam I get I'd have guessed it was a tidal wave."

Wrong answer to problem

[winkydink]

All this does is give bad guys a new way to extort money from companies. "Hey, Mr. CEO! Wire $50k to my egold account by Friday or I'll send pump&dump spam and get trading suspended on yoru company's stock."

The right answer is to unroll these trades and see who is profiting. Then start doing some analysis on the brokerages associated with these trades, because I'm willing to bet we're talking about "less reputable" brokerages. Now pull their securities dealer's license. Do you think that would cause other brokerages to look more carefully at sudden large volume trades on previously thinly-traded stocks? I do.
