Ranked second was Newton Investment Management North America LLC's global natural resources strategy, which returned a gross 62.49% for the year ended March 31.
Albert Chu, Boston-based portfolio manager, said in an interview that his team is "singularly focused on generating alpha."
While the strategy's benchmark is the S&P Global Natural Resources index, Mr. Chu said, "we scour everything. It's global in nature and (we can buy) pretty much any commodity. We take quite frankly a lot of enjoyment in finding these things that beat the benchmark."
The strategy focuses on finding underrepresented, undervalued commodities, and Mr. Chu said the team members think of themselves as specialists in identifying cycles before they occur.
He also said that his background in hedge funds provides a long/short perspective.
While he would not identify specific holdings, Mr. Chu said one of the things that contributed to outperformance was identifying natural gas as a place to take positions over the past two years, which has really paid off, as has selling positions in iron ore, where inventory was still building while the growth driver there has been the Chinese property market, which is controlled by only three or four companies.
Macquarie Asset Management, Philadelphia, was ranked third with its global natural resources strategy returning a gross 51.29% for the year ended March 31.
Samuel Halpert, chief investment officer, global natural resources equity, and Geoffrey King, portfolio manager, global natural resources equity, said in a joint phone interview the strategy is both sector- and benchmark-agnostic that averages between 28 and 35 holdings.
"We're not benchmarkers in any way, shape or form," Mr. Halpert said. "We're looking for the best individual ideas."
Both Messrs. Halpert and King said the strategy has benefited from what they term as a "misallocation of capital" due to the prevailing opinion that energy is transitioning away from oil and gas, as well as the downturn in energy prices that came out of the COVID-19 pandemic.
The strategy benefited primarily from "companies that were coming out of bankruptcy during that period and were coming out with clean balance sheets that were ignored," Mr. King said.
"This space is tricky because it's very difficult to go against a cycle," Mr. Halpert said, "Like even the best companies, if the commodity is going against them from stock performance in the short term, can struggle and underperform. So you definitely want to try to get the cycle right, but there are definitely some better businesses (out there)." Neither would name specific holdings.
Ranked fourth was New York-based Jennison Associates LLC's global natural resources equity strategy, which posted a gross return of 45.76% for the year ended March 31.
In a joint interview, Neil P. Brown and Jay Saunders, both managing directors and portfolio managers, said the strategy is very much a bottom-up fundamental strategy.
"We want to own companies through the cycle that are going to be around that can take advantage of the up cycle but also won't go bankrupt during the downturn," Mr. Brown said.
While Messrs. Brown and Saunders would not name specific holdings, Mr. Saunders said the types of moves that have benefited the strategy since the end of 2020 were seeking opportunities in companies that were on the edge of international exploration such as in South America.
Taking the fifth spot was Ninety One North America Inc.'s global natural resources strategy, which returned a gross 43.73% for the year ended March 31.
Tom Nelson, London-based co-head of thematic equity within the multiasset team and portfolio manager of energy and natural resources strategies, said in an interview that he believes the world's point of view on natural resources is changing.
"Resources companies have a role to play in a decarbonized future, whether that's mining companies providing nickel, copper and zinc, or whether that's energy companies moving away from oil and gas," Mr. Nelson said.
In general, the strategy has target allocations of about 40% each in energy and mining and 20% in agriculture, although Mr. Nelson said they can deviate very significantly from that allocation. In the last third of 2021, in fact, he said the allocation to energy had been about 21% and they have since doubled it.
Among the specific holdings that have benefited the strategy are Glencore PLC, a mining company, and Nutrien Ltd., a Norwegian oil and gas company, he said. He also noted that in general, gold and agriculture were big drivers because they're "less sensitive to the economic cycle."
