I've been keeping busy trading nat gas in the US, coffee/sugar based on the Brasilian drought, corn starting a nice trend looks like, and various stocks like FNMA, which has been ripping. Been a good few months.
W/r/t Ukraine, gazprom has long been on my hit list as headed to 0 probably eventually, but this Ukrainian conflict should accelerate the issue. Short gazprom large, long the russian index (RSX is one ETF) smaller to hedge everyday fluctuations.
Also short the ruble.
JGBs have been a pain in the butt, but they appear to be setting up another short setup again w/ the yen dropping more the last few days and JGBs unable to go up for a few weeks. Will look to buy puts on them again soon.
