In order for the t-trades to be associated with Hemi running out of authorized shares, Hemi would have to know about them and have knowledge of what the t-trade activity is related to. They don't... as can be seen in the September 27th press release:
"We are aware that some shareholders have issues and are concerned by after-hours stock trading. We would like to reassure the stockholders that Hemi management has no knowledge nor involvement in the after-hours trading that appears to be discounted stock prices to brokers. "
Then there was this from the June 11th press release:
"Neither Hemi nor Hemi's management have sold any shares in 2008 to the stock market and no market makers have been selling on the behalf of Hemi. Therefore, it continues to be Hemi's opinion that after hours postings are not shares being sold in volume but are predominately reporting of transactions of sales made during the day. "
This has been brought up more than a couple of times each time somebody, normally you, attempts to allude the after hours prints are due to Hemi dumping shares directly into the market.
