To be honest, I wasn't watching the share price toward the end of trading today, and did not know HIMR dropped to .0001 until later.  That said:

People often ask why a company might want to depress their stock price, or why a company with a depressed share price doesn't do something to increase share prices. The answer may be as simple as the company wants to do a stock buy back and retirement, and the lower the price, the more shares can be bought back with the funds available to them. This is often the case with penny or sub-penny stocks, because such companies often do not have large piles of cash just lying around. However, for higher priced stocks, a lower price often means higher trading volume, and this can be a motive in itself.

We know from HIMR's public statements that they are actively reducing their share structure. How can HIMR acquire shares that are already held by others? Would shareholders be more likely to sell their shares if the price remained low, or if the price dropped even further?  Once the share buy back and retirement is complete, what is likely to happen to share prices?

Something to think about.
