For those investing in the US market, how do you hedge the US dollars?

Gosh this really hurts me. I kept a chunk of USD in cash for a few months and just like that I lost a bit on forex.

However, there’s something I noticed. USD to SGD is down 5.6% in 6 months. At the same time, SP500 is up 20.3%. So this means that if you had been invested in SP500 for the past 6 months, you would have gained 14.7% in 6 months.

I know there’s a lot of flaws in this thinking, but it’s just a simplified visualisation. As long as your USD isn’t idling, and it’s invested in the market, the gains should be covering the drop in the USD.

If I’m very wrong, someone do correct me!
