1) not worth the effort: KBLB only draws a small amount per month and the amount of money needed to get the price down would not remotely be worth it. 2) Kim was a professional trader at one point and would realize if CSC did that and would find another source of financing (since the CSC deal is a line of credit all he has to do it just quit using it.
Could be something entirely unrelated to the company: someone with a huge load of KBLB getting a margin call because of something else tanking and they're selling KBLB instead of their other stocks because KBLB, being a penny stock, does not count toward margin equity so they'd have to sell a lot less of it than of anything else. Could be any of a whole lot of things. Because KBLB has such a low trading volue one big holder with such a problem could be doing this. Or could be numerous other things.
The bottom line is that there is no indication whatsoever that this is something directly related to KBLB.
