To those that don't like volatility :
Remember the Duke of York :
("and when they were up they were up, and when they were down, they were down, and when they were only halfway up they were neither up not down").
Much like a graph of the stock market!
Very difficult to tell where on the up/down scale you are at any moment, because the bottom and top points aren't fixed, so you can't measure the distance up or down from the peak and trough.
Usually, an extreme drop is followed by an enormous bounce (June 1972 to Dec 1974 down into the abyss, followed by doubling the next year, from 6th Jan 1975 onwards) and a stratospheric rise is followed by a damp squib plummet (1999 to 2000; 1987 Jan to July up, stagger in August to Sept, recovery, then plummet again in October; or recent Bitcoin prices).
The stock market is not unlike a trampoline:
Generally, the greater the rise, the greater the fall back, and the worse the fall, the greater the subsequent rise, all other things being equal.
For those like General Zod, try to rationalise what you are doing and why.
Things like:
How long do you intend to invest? If for 20-30 years, what looks like a big drop becomes (relatively) a tiny dent on the graph of 30 years. Equally, a big surge upwards will doubtless be scarcely more visible than an ant's back seen from 500 metres/yards on a graph of 30 years.
How much risk do you need to take? If you are like the heavily-indebted young lady who goes into the casino and puts her last £50 on a single number on the roulette wheel, only to lose that as well, it's clear that it was a do-or-die situation (definitely lose everything if you don't gamble, risk losing everything if you do, but with a faint chance that the problem would be solved). If you could survive without high-stakes odds, don't place high-stakes bets.
Are there lower-risk alternatives? (Not an easy one at the moment).
Suppose all investments fall in value to zero? Very, very unlikely, if you have created a geographical spread of risk, and if everything does fall to zero, that will be the least of your problems.
Everyone changes his investment ethos and story based on events ("Events, dear boy, events!" is what Harold Mcmillan is quoted as saying when he was prime minister and was asked by a journalist what could blow his agenda off the rails). Don't expect posters on here to be 100% consistent, because "circumstances alter cases". It's called 'being flexible'.
Let's hope for a reasonably steady few weeks in the market.
