Stem Cell Stocks 5/31/09: The Week That Was

Last week consisted of more sporadic trading for the stem cell stocks. I'm still trying to figure out if there is some correlation between the general market and the stem cell sector, but as of right now, nothing stands out.

Top Stem Cell Stock Performer(s) for Last Week:

- International Stem Cell Corp (ISCO.OB) = Up 47% for the week; Mid-week ISCO.OB received positive early results from animal trials designed to improve photorefractive keratectomy (PRK), a form of corrective laser eye surgery that offers an improved alternative to LASIK.

Worst Stem Cell Stock Performer(s) for Last Week:

Cord Blood America Inc. (CBAI.OB) = Down -15%; This stock was flat all week and then tanked the last hour of the last trading day of the week. It looks like frustrated traders are throwing in the towel.

Catalyst(s):

Nothing has changed from the last few months.

- M&A (mergers and acquisitions) activity will be key. I can't believe that there hasn't been any activity yet, but I think it will happen as the economy improves.
