Don't usually buy these types, but picked up a little bit in September & October, when I noticed some unusual bids coming in, as the ticker had barely ever traded for years.
I you look back at the historical record it only traded, a small handful of times, and very few shares, for many years, just seemed odd to me that anyone was bidding.
So for old times sake I grabbed a little, A) because there are so few shares available to trade, and B) because custodians have been grabbing a lot of abandoned tickers recently.
Trading history the last few years.
