I guess it depends on which one...
I just took profit on the crude etf, after I said I wouldn't but here I am full of cash (among other things), probably not much more than a week later; I was up 20% - reason? - the $C/markets are short term "overbought" a breather is in order.
Btw, take a look at the hourly on the HQU.TO index fund - it's like the Naz is going to turn back up here before the close....but it too is ST overbought, OTOH it's trending very strongly and could keep an oscillator like a CCI overbought for a long time - note that the RSI is finally showing some strength since bottoming out at the end of last October.
