You forget that by constantly buying and selling you are incurring more taxes. you are taxed less the longer you hold a position. The ETFs i own are very low cost and most are commission free. the trading fees are part of the price you pay for a security (cost basis) and losses are tax deductible. ALso im not a serious day trader..im just rebalancing my portfolio and now that i have available cash i will make periodic contributions over the course of the next 6-8 months whenever there are big dips. if there is a market crash i will unload 50-60% of my liquid savings and pump it into the S&P and my existing stocks. I dont think there is anything wrong with this strategy
Except that after the next crash, when it comes (and it's not an if), it may never recover (or not for a good long time).
If you were in the UK, I'd say spread the cash around those members of your family you can trust and give them all the maximum holding of premium bonds (low return, but chance of big prize, and no risk of loss). Maybe the rest into gold, or some other asset that has the most chance of holding its value.
In the US, I don't know, other than gold again.
Property? Well, it can appreciate, but with recent history, seems like a gamble.
I'm actually wondering whether land, pure and simple, could work. No property to need maintenance and looking after.
If rural and good quality, rent out to local farmer, and in some future crisis, land to grow food is always going to have a value.
If urban, and it's not built on, make it into a parking lot, and it can always be built on later and hopefully sold off later at a premium, when there is a need to build.
Just thinking out loud here
