EDIT: I don't usually respond to downvotes but it's really important to understand the stock market is a volatile investment. You shouldn't have money you're planning to use in the short or medium term in the stock market. It's a longer term (10 years+) investment.
At least in the Nordic countries, utterly uncontroversial conventional wisdom says something like:
* In your youth save almost-only in stocks; via some index fund, if you don't feel like being an active investor, following the market every day;
* Start with (funds that specialise in) high-growth (= high-risk) stocks; then, as you near middle age, slowly move over to lower-risk (= lower-growth) stocks (or funds specialised therein);
* In middle age, move over to having some part in state bonds;
* As you near retirement age, eliminate high-growth/risk stocks/funds altogether, and draw down the proportion of stocks/funds as a whole, going to an increasing proportion state bonds.
* As you retire, possibly move all-out of stocks / stock index funds and all-in on bonds... Except put some in an ordinary old bank account.
>your comments will be downgraded for lack of left-wing
The comment is kind of left leaning so I doubt that’s the reason for the down votes
