to clarify, when IB says that we have $500k SIPC insurance including $250k for cash and i have, for example, $650k in stocks and $50k in cash. My $50k in cash is still protected because of those $250k of cash insurance included into the SIPC insurance? Or because i am above $500k of SIPC, it is not. Also, i read that stocks we procure thru broker actually stays on broker name, not ours. If we want to secure ourselves we need to apply and get the stocks on our name. It takes several days and it is possible to get the paper certificate. The other thing is that if brokers fails, most probably all the positions would be taken buy some other brokerage organization but it is not guaranteed. Otherwise, why SIPC would only guarantee $500k for stocks. What do you think?
I don't want to guess the answers to your questions. In this case it is better if you ask your questions directly to IB, using your real account values.
