Are CENX and RIO both Basic Materials stocks?

Yes: both Century Aluminum Company (CENX) and Rio Tinto Group (RIO) operate in the Basic Materials sector. That makes this a direct sector-peer comparison, which is the apples-to-apples way to use the Buffett-Fit framework: the score weighs each stock against its sector's specific quality and valuation benchmarks (sector-relative bonus), so the cross-stock comparison isn't distorted by inter-sector base-rate differences.
