Beaten-down commodities markets might tempt investors to start tactically adding the asset class to their portfolios in a bid for diversification. That’s understandable, but likely premature, according to one analyst.
“Is November 2019 one of these great ‘tactical’ times to add commodities to a portfolio? Our opinion is no,” said John LaForge, head of real asset strategy at Wells Fargo Investment Institute, in a Monday note.

More important, those supercycle bear markets have lasted roughly 20 years on average, which can be a substantial drag on portfolio performance. That’s a “prime reason” why the firm hasn’t made a “strategic” allocation to commodities, he said.
“Commodities have been ‘knee-deep’ inside a
