Thinks s/he gets paid by the post
If they allowed for stacking, I would be tempted to do this...at least for umbrella policies.Do we have multiple insurance carriers for our home or auto? What if they don’t pay a claim? Do you have a second home in case yours burns down?
If you have access to local checking/cash, good access to credit, I see no reason to add another level of complexity to investing.
Just because it makes no economic sense to have multiple insurance carriers for home/auto, doesn't mean it doesn't make sense to reasonably spread investment accounts. I worked 30+ years in I/T and a number of years with a top tier financial institution - great, smart, but still things happen.
In addition, different firms have differing advantages. I have both Schwab and Fidelity accounts, both private client. Schwab's "Think or Swim" is superior to anything Fidelity has. Fidelity was better on my SPCX IPO (by far) over Schwab.
But yes, simplification and consolidation does have advantages - and I've been slowly consolidating across those two platforms.
