Impossible to answer. Perhaps some exposure to both is best for your "oil spill remediation" portfolio.
At least for Friday you would have seen some cushioning or some 'green' for the drop in ACLH if you had enough BCLE
Maybe they should both be viewed as tradeable while sorting out what the long term might entail for both of them. Contract announcements for either or both are the wildcards.
You can certainly buy more shares of BCLE @ .0119 than you can of ACLH @ .04, and if they're both on their way to .10 you can see where the most leveraged gain lies.
For all any of us know they're both .20-.30 stocks as this disaster plays out.
