List high-dividend ETFs (>4% yield) with lowest volatility (beta <0.8).

```reference [{"type":"table-json","id":6}] ``` Although we queried the full U.S. ETF universe, no fund currently combines a trailing-twelve-month dividend yield above 4 percent with a beta below 0.80. The table therefore displays the 20 high-yield ETFs that come closest to the requested volatility threshold, ranked by their beta values (all between 0.86 and 0.96). These candidates were identified by first retrieving each ETF’s latest dividend yield and beta figures from the internal database , then filtering for yields above 4 percent and ordering the results by ascending beta .
