One certainty in stock markets is that the next crash will come. It WILL. Maybe not in 2 years, but in 3. They tend to be in the newspaper after it happened. No text service to get out in time.
If you have no clue what to do with inherited moeny you don't need, there are a few options I see:
1 - stay in cash, hope that you'll find a way to spend before inflation happens (it's happening)
1A in a bank account, low interest (subject to bail ins)
1B in paper in a safe (place), subject to burglary
2 - any sort of dividend generating paper "asset"
3 - precious metals (purchase power parking long term, with short term up- and downsides. Don't leave a paper trail.
4 - stocks (gambling it will outpace inflation until you sell). This is usually does, until it doesn't anymore.
5 - Do something productive. Build an indoor venue. Go into production with you invention. Open a franchise. Donate to something close to your heart.
6 - Real estate. Detroit has good prices. Argentina is on 50% peso discount of late. Both cases, a bomb or bulldozer can ruin it. Insurance doesn't cover everything. will insurance rebuild Gaza?
Having utterly failed at increasing my fiat position (lost all in a...wait for it...CRASH), I have decided that I care more to hold long-term purchase power. Thus precious metals. My choice for silver over other metals is a simple one each time, although it's a long list of reasons. For me, physical silver is a high return generating asset. No-one is forced to see it that way, and it sure helps me if you don't. No hedge fund offers the return physical silver offer me. And they don't do it for modest portfolios.
My investment portfolio is purchase power I don't need right now. If I need it in 10-20 years, I need it to still be there. None of the other options offer certainty. Metals come closest. Its logic appeals to me.
If anyone is the kind of genius that gets into financial markets for the first time with Dow at 17K and interest at zero, and makes good revenue from it, more power to you. I have studied markets for half a decade now and I can't find a way to make that any less risky than roulette.
It's the worst possible market climate ever, that I am aware of, to be a paper/digital based investor would anomalous luck inherited along with the money.
In these times, I worry more about not going broke than about not getting much richer. But I did choose a path with (in my vision) largest likelihood op upside potential (expressed in real estate) in the ~10 year time frame could be longer, I won'y complain. By then most current investors will have taken huge hits. These markets are not going to be OK forever. And one should not treat as a game of chicken. Who gets out first does not necessarily lose.
