Those who would like to gauge their risk tolerance can go through a hypothetical scenario where the market declines x% by next year, while income is reduced by y% for z amount of time.

For example, 50% decline, 50% income reduction, 2 year duration.

This is to ensure that you have sufficient buffer in your emergency fund and fixed income combined before tapping into equity selling in worst case scenario.

Bogleheads had a few guys who had the influence of great depression 1929 (family asset wiped out, and they were in their early childhood). These were counted as real experience facing macroeconomic shocks and severe economic crisis.

Malmendier & Nagel (2011) had a paper tracking the risk taking behavior of these group of people. Overall, the experience was so painful leading to generations of conservative investing even after so many decades.

For Malaysian, perhaps some real experiences surrounding Asian financial crisis 1997 can provide a very good argument to young investors who need meaningful percentage of fixed income in their asset allocation.

Hmm, I am a little on the younger side, so I'm not sure how valid my opinion is, or perhaps people would think less of me for being on the paranoid side, but I'll share it anyway.

First of all, I invest primarily in VWRA, an Irish-domiciled ETF. I will never have an holding of more than 60k in US stocks/ETF/cash in my IBKR account so I shouldn't be liable for any US estate tax concerns.
I've told my close family that I have foreign investment, and that in the event of my demise, they are free to help themselves to it, at least I would have paid for my own funeral.

As a backup plan, I've also prepared a document detailing my access info, screenshots of how to liquidate my portfolio, my withdrawal routes, as well as instructions on how to contact IBKR for assistance should they are unable to or unwilling to pretend to be me and access my funds. Of course, there's always an option to proceed with my will and death certificate to access it legally - if it does come to this, and they find it worth the trouble.

The document is then stored in an encrypted volume requiring PASSWORD_A, attached to my gmail on scheduled send in 6 months, and also stored in a physical thumbdrive, mentions that password will be emailed in 1 month.
Then in another gmail account, PASSWORD_A is also on scheduled send in 7 months.
Then, I set an reminder to myself to renew the send date every 5 or so months to keep it from sending out until I die, acting like a dead man's switch.

This should keep my access detail safe even if I made a mistake now and then (e.g. forget to renew encrypted volume send date), stolen, or my relationship with my family deteriorates in the future.

If it sounds mega paranoid, it is. I am a selfish person and my benefits should always comes first above all else. I wouldn't trust a second soul to access any of my finances as long I am still alive. I've seen enough bad story regarding family and money as it is.

TL;DR: Family is aware of where I am invested, will have access to my investment as soon as my death certificate is issued, or in 7 months as a backup.

From what he wrote it seems he will not share his passwords as long he’s still alive. Meaning using lawyer letter or death cert to claim those investment. If so it will incur 40% estate tax if investments are in IBKR.

If you trust your loved ones enough then you can share the logins. Even if they were to access and sell all your shares they can’t withdraw to their own account.. need to withdraw to account with same name.

But sometimes is not about the greed part.. is how some family members might make noise, lecture you, keep probe and criticise etc type. If so I understand why some would not want to share their logins also.
