Only stock exposure is in my UK government pension. I have pretty much written this off as a guaranteed reasonable income when I retire which is projected to be 2043.
Any one with FIAT money tied up in a product could theoretically see massive devaluations if legacy financial institutions are slow to switch to crypto - personally think this is inevitable with my pension fund.
I learnt about the stock market problems from watching Max Keiser:
No price discovery in Stock trading, all is automated trading, low volatility is a worry.
FANG stocks are killing competition in USA and elsewhere, and are the only ones making profits - Facebook, Amazon, Apple, Netflix, Google (Alphabet).
FANG stocks - no level playing field as pay little tax.
Many companies are doing share buy backs to inflate performance.
Intrest rate apartheid - big businesses are too big to fail and just get bailed out with zero percent interest rates lending from the US Federal Reserve.
Who knows when the stock crash / correction will occur? Personally would get ou completely of stocks - if I had any. 10% of portfolio would be my absolute maximum if having a varied and balanced one. Gold, Silver are obvious alternatives as China may be about to come off Dollar pricing for oil and linking to gold - gold and silver may increase significantly, but nothing like what is been seen in crypto.
Stress test your portfolio, this may help to decide percentage exposure to stocks you are prepared to risk.
