In these volatile times, what are you doing to protect against drawdown in short term ?

Hiya.

Here is how I am investing:

401k - not maxing out. But still putting a decent sum to optimise for pretax

The rest of my investment is in brokerage. Every month, I put money in these 4.

voo - 50%

vxus - 20%

mtum - 20% (momentum index)

agg - 10% (ishares bond etf)

I currently have more than 90% exposure to equities. And since there is a high correlation between my 401k, voo and mtum, I feel like I am not diversified enough.

How would you hedge against the drawdown of the US market, which I fear is eminent, would you increase the percentage in vxus and agg, and maybe invest in gold as well? Is gold a good diversification strategy?
