No. Not many of them, anyway. Can't even imagine why anyone would ask the question. Sellers currently are selling into higher volume and higher prices. Question doesn't apply to CWH as currently situated.
Not planning to sell for a long time. My plan is hold, write covered calls every 6 months @ 30, and count the dividends. Why create stress. If common goes below 25, or if Pref-D goes below 20, I might consider buying more.
