Mesabi Trust Plunging 14% (MSB)

Mesabi Trust MSB is trading sharply lower today, which concerns me, since I don't see any news. Mesabi Trust owns mining rights on taconite properties in Minnesota. The Trust conserves and protects the trust estate and collects and distributes the income to certificate holders. The only thing that comes to my mind is a lower Baltic Dry Index, which is havily impacted by iron ore shipments, so it's possible that with lower iron ore shipments, and thusly, iron ore prices, that Mesabi Trust is seeing the imapct on its shares. At last check, shares of MSB were off $7.42 to $45.74 on more than 1.5 million shares. The average daily volume in the name is around 300,000 shares.
