Meanwhile, countries that could benefit form the changing weather include New Zealand, Netherlands, Argentina, Norway and Denmark, according to Nomura.

ETF investors can also track these countries through the iShares MSCI New Zealand Capped ETF (NYSEArca: ENZL), iShares MSCI Netherlands ETF (NYSEArca: EWN), Global X MSCI Argentina ETF (NYSEArca: ARGT), Global X Norway 30 ETF (NYSEArca: NORW) and iShares MSCI Denmark Capped ETF (BATS: EDEN).

Additionally, Nomura anticipates that the El Niño event could cause large supply disruptions in the global food supply and add to a surge in food prices due to feedback loops like hoarding and speculation. Consequently, the firm believes companies like Monsanto (NYSE: MON), Potash (NYSE: POT), Mosaic (NYSE: MOS) and John Deere (NYSE: DE) could benefit as farmers grow flush on the higher commodity prices.

The companies are also major components in agribusiness-related ETFs, such as the Market Vectors Agribusiness ETF (NYSEArca: MOO)PowerShares Global Agriculture Portfolio (NYSEArca: PAGG), IQ Global Agribusiness Small Cap ETF (NYSEArca: CROP) and iShares MSCI Global Agriculture Producers ETF (NYSEArca: VEGI). For instance, MOO’s top holdings include MON 7.4%, DE 6.9%, POT 5.5% and MOS 4.0%.
