Are 401K accounts non-marketable securities

Yes, 401(k) accounts are considered non-marketable securities. This means that the investments within a 401(k) are not easily bought or sold on public markets like stocks or bonds. Instead, these accounts typically hold a selection of mutual funds, target-date funds, or other investment options chosen by the plan sponsor, which cannot be traded freely. Thus, access to the funds is generally restricted until certain conditions, like retirement or reaching a specific age, are met.
