It does take time to build up information yourself so you can understand all the things a personal advisor may be presenting.
Also understanding about your own particular situation - if you have retirement/pension, 401k, IRAs, Roth IRAs. If there is a need to consolidate some things. If you can benefit from instruments like Annuities (if you don’t have pensions). However, take some time to understand what you have, what your financial goals are, and how you can get there.
Hopefully the Vanguard personal advisor is going through a risk assessment evaluation for you - so in addition to your age, it tells how risk averse you are, and where your current investments lie on risk assessment. Also how you can have your funds last till age XX (with plugging in the age). Ask him/her a lot of questions and ask him/her to guide you on resources you can study to be an informed client.
Also understanding how taxes come into play. If you have IRAs and want to roll them into Roth IRAs, and if and when that can be done. If you are pre-social security and Medicare, understand how that works in your situation and for your decisions.
Read up what you can. Go to a local bookstore and sit down with some of the books available there - and decide what one to start with on your personal education path.
You may have access to various web sites through your own 401k or other assets. For example, my 401k was through Fidelity. When our FA group moved their client stock investments (which were in several risk groupings) from TD Ameritrade (which was acquired by Schwab) into Fidelity (to obtain the same ‘deal’ on cost of various transactions), I had prior experience with Fidelity’s web site and web resources.
DH’s 401k is with Prudential (DH and I manage these investments), but it had been previously with Principal and with Dreyfus. That is our largest stock account, and no need for us to have under our Financial Advisor’s ‘umbrella’ because it is fine with our risk assessment to have those assets managed by us. When that fund grows enough, we spin off purchasing an Annuity, if that is a good call at the time (Annuities that are offered at a particular time can be better at some times then at others). Our FA applauded our purchase of an Annuity (that met the ‘looking good’ test on returns) out of a chunk of funds July 2021 – many would have wanted to ‘continue to ride’ on these funds in their stock portfolio; well Jan 2022 was the big stock market drop (which continued with calendar year negative returns). Our 401k is still not at the level it was Dec 2021, but it is recovering, and is not affecting our life or SWAN status (sleep well at night).
No question is a dumb question.
