I think the primary reason people have been discussing, that investors are cashing out of ASICMINER to invest in new startups (unwisely IMHO), is likely one of the primary causes of the low share price. Others likely include the lower dividends recently, the lack of information about new hardware despite expectations of such, and a lack of updates from friedcat. Remember, until fairly recently friedcat was providing weekly updates every thursday like clockwork, and that has stopped without explanation.
The fact that news about new ASICMINER hardware is imminent, competition is unlikely to seriously compete any time soon, and that friedcat is working just as hard as every in spite of the lack of official updates leads me to believe that it is in fact an fantastic time to purcahse ASICMINER shares.
I must agree watching it at 3.6 even I think that's a steal
