Warrants trade at a rate of roughly 2x the common stock usually...
If you are a shareholder and want the maximum possible return on your investment with, at this point in time no financial risk, consider switching to the warrants issued at the time of the public offering, they trade under the symbol CSCIW and they don't expire until October 11, 2018. The excersise price is $1.25
You can sell CVM, buy an equivalent number of CSCIW shares, and take almost 50% of your money off the table. Or buy additional shares, it would be up to you.
From this point forward, if CVM reaches $2.00, the stock will appreciate about 100%, CSCIW would appreciate almost 150%.
I made this switch in several stocks like GALT and ICLD and it's worked out great for me and several friends, you should think about it...JMHO
