I don’t see that as a possibility - at least it’s as remote as the spx dot shorting down 50percent in a few seconds (how do you hedge for that?) but the cost of having 4 brokers in terms of bookkeeping and capital management (margin, etc) seems really annoying.
%% Good points; IBKR suggests 2 brokers. Really 2...... good brokers sounds like one basket but with a good wise wall between the 2. I do want more than 2 income streams /2 locations or more; but having raised laying hens/ capital markets are not as fragile as hen eggs/LOL. Went in to the bank once + the stinkin' pens would not write; power went off @ nite +cold ink to thick to work much Some how we struggled thru[I noticed yesterday@ bank, now use an electric pen/ but that'$ electric dependent]
%% EXACTLY\ + seldom does any of those failures cost traders/investors lots money. Good law sorry its not been on books since 1776; banks execs get profits clawed back 5 years foe stupidity or woke-broke ESG stupidity like SVB. Diversity in time, different banks, location , diversity in price, some but not lower priced stuff, not just TX location only, even though i would overweight any home state, try to avoid woke \broke\ ESG[ s = satanic mr musk warned] try to avoid hi tax areas when possible, try to avoid gov i dont like, CO has changed for worst so may never hunt there again, not a prediction different degrees of leverage, different assets , RE, IF i spot crooked character like SVB\ Jon corzone[GS reject maybe] get out of that zone. SCHW + IBKR = so well run , dont need to divy it up much.......
