I think your advisor's information is based on this news report:
Fidelity sees $9.9 bln outflow in Jan - research | Funds | News | Reuters
It says that Fidelity's stock and bond flows suffered $10 billion outflows in January,
not including flows into and out of money market funds. When you include MM funds, Fidelity's net inflow was $14.4 billion. So I think this is just a result of people moving a ton of money out of the market and into safer investments.
Fidelity is a highly regarded institution and I don't think you will have any problems with them.
I prefer Vanguard but to each his/her own.
