PCEF hunts for yield among publicly-traded closed-end funds (CEFs). CEFs differ from ETFs in that they are closed for additional new investment and share creation. Lacking ETF's baked-in creation/redemption plumbing, CEFs have no outlet for arbitrage to keep market price in line with fair value, so CEFs often trade at discounts or premiums. PCEF favors CEFs that trade at discounts on the theory that such funds are more likely to appreciate in value and because it increases the yield relative to actual price paid. PCEF holds three flavors of CEFs: Investment-grade fixed income, high-yield fixed income and equity covered-call strategies. The fund competes directly to its upstart ETF-of-CEFs rival, YYY. The fund and the index are rebalanced and reconstituted quarterly.
