I would make a guess that the share price is down due to the fall in NAV. But due to deteriorating conditions in the credit market for less than investment grade debt during Q3-11, the fall in NAV is no surprise - and NAV's have been falling for almost all BDCs. [The NAV fall was even less than what I expected.]
Also, the market needs to wait till after the conference call to weed out the one time events that may have colored the [great] Q3 numbers. But at least until the call - this camper is happy. the big fall in incentive management fees really helped the NII/share. And total investment income was up a good bit - too.
Spent a little time looking at TAXI a couple of years ago and chose not to invest. Feelt that there was too much opportunity to have gvmt involve themselves in the issuance of medalions. Don't have much capital to invest now so will stay with hose that I have for additional investments.
