No, the model would not necessarily work overnight (in the case that the fund changes it's weightings in it's underlying holdings)
It works well intraday, especially if you see lots of selling in the ETF, like, if one broker keeps consistently selling 500/1000 share lots at a given price range and the market depth of the bid keeps flopping around..usually easy to find a bottom/oversold condition.
The only problem is you have to watch carefully because the inneficiency is usually removed quite quickly, but for example, I could pull $.40 out of a $3.52 buy in one day if I caught it when someone really wanted out. (MLY.TO)
