Unless DNP management dilutes your holdings and fund earnings with more shares, ie "Rights Offering".
At least for now, DNP's dividend is significantly Return of Capital. As a shareholder for more than 18 years I say the "Offering" has diluted earnings per share and decreased appreciation from roughly $11 per share to around $9 per share, or 18 percent. We were better served with the same dividend from earnings and share prices at $11 than now. That is why Buy-Backs make sense in many instances.
Everyone must sell at some point. That is either the shareholder or his estate. Nothing remains the same forever, or even a lifetime. ( I suppose that's why we have diluting "Rights Offerings".)
