Now that much of my research work is done as part of my job, I don't have much time to devote to research on the sidelines. But here's a recap of what's still ongoing:
The yield curve play is still valid: https://www.fintrinity.com/marketview/trading-the-inverted-yield-curve-2/
Seasonality in indices can still be traded: https://www.fintrinity.com/blog/january-effect-idea-nov-2019/
Trading the outbreak is not the most convincing for me - I did it mainly to push myself to see what opportunities there are in situations like these, but still have not found anything with high conviction.
I've closed a good bit of my long TRY trades (using options to exit), as it keeps crawling lower (and the carry is diminishing) and so the risk reward is less than what it used to be.
As US markets are near ATH, I've taken the chance to add to long Puts and opportunistically selling Calls.
In FX markets, short term opportunities are still present in short USDCAD.
Commodity futures are still a go, riding on my past research, but not having the time to discover new things.
