We saw solid gains in most markets this past week, but intraday swings were massive as high volatility persists. In base metals, tin was the biggest winner for the week (up almost 13%) followed by nickel (up by 5.2%). Copper and aluminum rose by about 4% each, followed by lead (2.1%) and zinc (up by 1%). The cash to-three month spreads moved into a backwardation for both copper and aluminum. But contangos were evident in the rest of the group.
