There are two parts to the reason my position in JBII is very small.
1. At this point I would say I'm more concerned about the impact of a financing in combination with their low cash position. IMO they need to do a financing very soon. Economics is also a concern but at this juncture it is lower than financing. Also, I'll add that I think a financing will be relatively easy if they can prove the economics.
2. In combination with #1 above, the other reason my position is small is that generally speaking I can be the first or very close to the first buyer of stock on any news. Since I trade full time a stock like this can be monitored closely by me and I generally can get in quickly. Also, the stock is pretty liquid so I can buy in size relatively easily.
