Comments apropos, and according to Morningstar, the MER is 1.58%, not the 75bps cited here. Another alarm bell when you look at the NAV and the market price history over its life. Radically different. What does that signify?

Market pricing only showing for a much shorter lifetime than NAV history. Was this a closed-end fund in its early days?

As said here, the covered call strategy on blue-chips seems over the top, and the ROC nature may well indicate it is far riskier than the comfort of the excellent portfolio holdings.
