Speculation on (low) volume and (fluctuating) price lately:
Individuals / families who have been with LBSR for years are holding, or buying when the price dips low enough to be tempting. I can't imaging anyone who has weathered the storm of the last 5-10 years dumping their stock now, unless they really need some money.
People who have gotten into LBSR in the last 6-12 months, and have not done any due diligence, might be willing to sell for a decent profit and move on. Probably not too many of these.
Lending companies (1800 Diagonal Lending and others), if they follow relatively good business practices (but then, if they followed relatively good business practice, they would not have loaned LBSR money in the first place), and have had their loans converted into stock, would probably have sold enough shares to recoup their loan amounts and reasonable interest. After that, they would probably continue to sell (relatively) small amounts only if they needed money to loan to other clients. I see sales by these companies as at least one reason for large price dips - $0.17 on March 1st, and $0.10 last Friday. They would put out a sell order way below current market to make sure they sold all they needed.
Individuals who have loaned money to LBSR should be glad to convert the loans to stock and hold it.
Just speculating, mainly on the low volume.
