50% drop in portfolio.... i doubt anyone can really mentally prepare himself or herself for that... ...
really depends on the circumstances..
Which one you think will handle it well..which one will have sleepness nights... which one will cut loss... which one will jump?
Close your eyes.. imagine you were that person... what would you be feeling and what is your response to a 50% cut in portfolio value. Or better... think of 20% first, then 30%, then 40%... which point will you buay tahan and cut..
1) 20s just working and building stock portfolio using his active income. Portfolio size is less than the annual salary he gets. Not much financial commitment (like family, mortgage).
2) 30s working and married. Portfolio size is 5 years of his annual salary. Heavy financial commitment of family and mortgage.
3) 40s working and increasing instability in the job (example, once retrenched hard to find a equally good paying job - please dont tell me of the satki people who are top echelons who will find even higher paying jobs. Let's talk about the 80%). Could be heavier financial commitment or lesser(depending on children age and mortgage payoff). The portfolio size is 10years of his annual salary.
4) 50s nearing retirement and increased probability of retrenchment and lower paying jobs. Hopefully no more financial commitments. Portfolio size is 15 years of his annual salary.
5) 60s already retired and no more ACTIVE income. Hopefully no more financial commitments but increased expenditures on healthcare. Portfolio size is 20years of his annual salary.Dependent on the POrtfolio for income.
6) for person 3,4,5 , please replace the portfolio size to become 5years of his annual salary. This is the retirement money.
7) for person 3,4,5, please replace the financial commitment to still having mortgage to pay off. (or a atas lifestyle to upkeep).
