Biotech Values

[mcbio]

Why don't people list their holdings?

I'm just curious why most people don't list their holdings on here. Dew has his two bios on his profile and I have mine displayed. What is preventing the rest of you from revealing your cards? I can understand if you're thinking about taking a big position in a small bio and maybe you don't want to disclose that or something (not that I can move the market or anything though). But, if you already own a stock, I don't see what the concern would be about disclosing your position.

So...who's with me? What do you own now? And, dare I ask, what are you considering?
