Of course you do. I buy a share. I loan it to you. You sell it short. That buyer pledges it to a third person. Et cetera.
You can (assuming you haven’t exhausted all available independent investment opportunities with equivalent risk/reward profile) reduce risk without reducing expected gains.
Doing so (assuming you were investing suboptimally for your the prior risk level and expected returns) involves reducing in the part of the distribution above the mean offsetting the increase in the part below the mean.
Buying a 10% interest in each of 10 lottery tickets (ignoring practical risks associated with deals to split winnings) doesn't reduce your gains compared to buying one lottery ticket, it just reduces your risk.
This is the whole point of diversification.
If the goal was to reduce risk then pensions would be better off being held in cash. But pension funds dont have enough cash to meet needs so they have to grow.
Moreover some asset that is risky on it's own can decrease the risk of the entire portfolio. From a quantitative perspective, specific risk from an asset is largely irrelevant (and doesnt carry a risk premium), because it can be diversified away to 0
Wikipedia say it's a pension:
> a 401(k) plan is an employer-sponsored defined-contribution pension
https://en.wikipedia.org/wiki/401(k)
The US Code also says it's a pension - 401 is 'Qualified pension, profit-sharing, and stock bonus plans' and 401(k) is covered under the 'qualified pension' clause ('qualified' meaning the same as 'defined contribution' in this case.)
If it looks like a pension and quacks like a pension and is called a pension in law and is called a pension in non-technical resources like Wikipedia then... it's a pension!

Or maybe for clarity consider the word "pensioner"
Is it still a "pension" when contributions are made your whole life and it crashes to 0 and you never make a withdraw?
Most people call defined contribution plans "retirement savings" plans and defined benefit "pensions". While conceptually at a high level they are the same thing, the difference is in who bears the risk when the plan is underfunded. In the first the risk is entirely born by the individual which frequently doesn't have any choice in the investment companies much less the investments. The latter the risk is squarely on the shoulders of a larger organization, be that a company or as the last resort the government. Aka the risk is socialized/insured.
Yes?
Why do you think defined-benefit is so important as to be the default, gold standard which owns the name 'pension'?
No didn't think so...
> PBGC is a federal agency created by the Employee Retirement Income Security Act of 1974 (ERISA) to protect pension benefits *in private-sector defined-benefit plans*
Which means by implication that there are pensions in non-defined-benefit plans (ie defined-contribution, like 401ks). Also note that this quote indicates the PGBC doesn't protect public-sector pension plans, which means your logic leads to the ludicrous conclusion that public-sector pensions are somehow not pensions.
This level of confidence combined with this level of ignorance is not a good look.
Whats the difference between a government backed pension guarantee and a government pension?
I think your misunderstanding the purpose of the PGBC, particularly if you consider the state of things when it was founded.
But so what they don’t cover it? Why does that make it less of a pension? Government pensions also aren’t covered by it. Are they not pensions as well?
Through your pension you're probably an investor in tens of thousands of companies and funds.
