The TBT is an inverse ETF of the 20+ year treasury. As the fed lowers interest rates and offloads their balance sheet the price of treasury bonds will go down, meaning this ETF will go up. Michael Burry recently made a bet again the 20+ year treasury bonds.

The SRS is an inverse ETF that is short on the housing market. Which means when house prices fall this ETF goes up. As the forclosure ban is lifted and interest rates go up there will be more supply of houses and less buyers, meaning the price of real-estate will fall.

GLD is an ETF that holds gold. Safe play during recessions.

DBA is an ETF that is an Agriculture Fund. As the shortage in fertilizer causes a shortage in food, they will be able to raise prices and increase profits.

The SPXS is an inverse etf on the S&P500. This means when the whole market goes down this goes up proportionately.
