LME copper rises $82 to $14,420/t; aluminium slips, tin gains

The dispersion matters more than copper's gain: nickel and tin posting the largest moves while aluminium and lead softened suggests this is not a single macro risk-on impulse but metal-specific positioning. Tin's outsized jump against a modest copper advance points to thin liquidity amplifying moves, which cuts both ways. Whether the base-metals complex keeps diverging along supply-specific lines, rather than trading as one bloc, is the open question worth tracking.
