Some other things you can do:

1) Reduce your portfolio delta. If you're exposed to the long side, you can pick up some shorts, buy some puts on existing positions, or sell vertical calls to overlay.

2) Collar your positions. That involves buying a put and selling a call at the strike. This should be a net gain which reduces your risk (and reward) to the market.

3) Diversify into non-correlated investments. That means expanding out of one asset class (in your case fixed income) into several others that may not necessarily move with the market. That can include some inverse ETFs.

4) Go cash until you have a plan.

Disclaimer: Use at own risk. Due diligence is your friend.
