If you don't plan to actively make this a hobby/passion my advice is to spend the least amount of time/effort possible thinking about your investments. Don't look at all the stocks or funds that doubled in the past year and try and chase past performance. The best advice for the average person is to invest in a cheap broad index fund for something like the sp500 and then make regular contributions to cost average regardless of which direction the market turns. Don't try to time things, a lot of people got burned in the 2020 crash and sharp reversal. People spend a ton of time and money trying to eek out a few percent gains over the index and many fail to do even that despite the cost and effort expended, so you as an average investor have no chance to get one over on wallstreeters; at best you'll get lucky but odds are not in your favor.
As for what to invest in, I'd suggest a low cost sp500 etf like IVV if you're 10+ years from retirement. There's also robo advisors that'll do a model portfolio with some diversification, typically some version of the 60/40 stock/bonds portfolio. There's also target date retirement mutual funds that will slowly shift to a larger income/safety focused fixed income allocation as you approach the target date for retirement.
If you want to be more hands on a few suggestions to consider:
If you want to try stock picking keep it to a modest allocation of your portfolio, maybe 20%
Get some international equity exposure, a mix of developed and emerging markets, small and large cap, and a balance of growth/value. You can most likely just buy both of the large ETFs like EFA or EEM and call it good or you could also grab some China/Vietnam ETFs like KBA or VNM if you want to be overweight these regions.
If you have a fixed income allocation I'd suggest getting some Chinese Treasuries exposure, there should be a couple broad international ETFs that do that or you could buy a fund like CBON for direct exposure.
Also consider adding some exposure to carbon credits, maybe 3-5%. It's basically a given that the price of carbon will have to keep going up to get emissions down, so it seems likely this will be structured to keep going up by politicians. KRBN is a good fund for this.
Let me know if you have any questions.
Food prices are expected to rise due to higher input costs for fertilizer productions already, so any disruptions will have an upward movement on prices. Article from a few weeks ago:
