Commodities are forging a record-setting run of gains that straddles the end of 2017 and the start of the new year as crude oil notches multiyear highs and investors bet that booming global manufacturing output will help to sustain rising demand for raw materials.The Bloomberg Commodity Index, which tracks returns on 22 raw materials, posted an unprecedented 14 days of gains to Wednesday, closing at the highest since February. The index is poised for further gains as metals and oil climb higher, supported by supply disruptions, a weaker dollar and improving demand. Palladium, a metal used in car exhaust systems, is approaching an all-time high.
Commodities eked out a second annual gain last year and heading into 2018, banks including Goldman Sachs Group Inc. are optimistic there will be further advances. Last month, the firm reiterated its 12-month overweight recommendation.
