HUI is like a big slow mutual fund mixed with winners and loser stocks. I found this…
“Launched in March 1996, the NYSE Arca Gold BUGS Index includes companies who hedge their gold production for no more than 18 months in advance.1
For this reason, their share prices—and, by extension, the index—are very sensitive to short-term movements in the gold price”.

The Gold run from Oct 16 at $1850 to Dec 4th intraday to $2150, I think convinced us all we were going much higher.
