$DUST 29.60 $NUGT 29.92 -…

$DUST 29.60 $NUGT 29.92 – the stocks are trading at roughly the same price again, but over time the crossovers are at lower and lower levels as the tracking error from $GDX takes a toll on both stocks.
The best way to take advantage of this is to be short calls on both, adding Theta decay to the equation.
Just be prepared for occasional big swings.
