Any idea why the sector has been put under "Unfavorable" category?

Yep, that ones a mystery. Has been in the top 10 RS groups for months, and no.1 currently.

I think there could be reasons for it.  I've calculated a market breadth chart.  There are relatively few constituents in this pool of stocks.  key points for me are that aluminium itself is in a pullback [1], the Weinstein Momentum [1] is near zero, but it has not crossed the line but might easily rise [2].  However, on the longer term the Weinstein Momentum and the 1% A/D have both been in a long decline [5 & 6].  The % stocks above their MAs [11, 12 & 13] and the Silver and Gold Cross indicies [14 & 15] have been declining.

Of course, what would have been more objective is if I had undertaken the analysis without the knowledge of what has been said in this thread.
