All the money coming in through the creations shares is going to skew the dividend for a couple of months. You will have to wait until the interest on all the new bonds bought with the creation shares comes on line.
The Jan 2012 payment was $0.218698 dividend and $0.264078 long term cap gain.
Therefor for two months, the monthly dividend was below $.22, and I expect tomorrow's trend will follow this trend.
Because they recycle almost half of their holdings each year, and the yields offered on new junk bonds are going down as more money floods into junk bonds to chase yield (reducing their incentive to offer high coupons to lure new bondholders), the yields are now as low as seen with PGF and PFF, whose yields have not dropped as much on a year-over-year percentage basis.
Based on this, I see no need to own JNK anymore (as I also own less-risky and better yielding PGF). I'll wait for the bond bubble to die and the dumb money to filter out before I buy in again.
You can check the "historical prices" in LEFT list of answering question. On this page, you'll see 4 choices...daily...weekly...monthly...dividends only. Use "dot" on dividends, push "get prices" and you'll see the date (each one)and the dividend for that month/year. This is info every stock has, so easy to see all useful info as you look for
