How can consistent economic growth over the long term be supported by the market?
Surely there will be a time, even if it's only theoretical, where a company can only grow to a certain share price and demand? Thus over the very long term there will be 100 companies with their highest share price trading off short term consequences which result in a lower price with others who are experiencing higher than valued growth?
So why doesn't the FTSE eventually reach an equilibrium, or is this just something that hasn't happened yet and won't on a normal timescale?
You have it the wrong way round. The market is supported by consistent economic growth.
The main reason why a share price increases is that that share is likely to pay a decent dividend.
Bare with me here as I'm pissed and on my phone.
So company A has a share price of 100p and releases a dividend of 7p.
Company B has a share price of 200p and release a dividend of 7p.
[Assuming everything else is the same etc as there are so many variables]
Investors would look at the two companies and prefer to buy company A as their dividend is 7% of cost of the share compared with 3.5% at company B. This then pushed up the share price of company A until they reach and equilibrium, which would happen very quickly and may involve the share price dropping of company B.
Now the economy does well let's say in the next year and both companies increase their profits as consumers are buying their profits.
This means they can share that wealth with investors (shareholders) again and the share price again rises and more people buy (the limited number of) shares available to benefit from these increased profits.
This is why companies like Apple continue to rise, as they made record profit after record profit and pass that profit, after investing in its own future, to its shareholders.
Now as an index is a collection of the top shares, by its very nature, it has the success stories and if a company does crap over the long term, it loses its place (like relegation from the league) and a new company that is better managed/better equipped to address the needs of the consumer, replaces it.
As an example, the week Woolworths went out of business, The Pound Shop released record profits.
So long as GDP increases, there will be companies making record profits, new industries are built and replace the old industries that fall by the way side, but the index will continue to rise, over the long term.
Squirts is sort of correct, market sentiment accounts for very short term fluctuations, but long term it is driven by economic growth, entrepreneurs, new technology and innovation.
Think of it as being like a tide that only ever comes in, sure, there are waves that make the water go back and forth and water rises and recedes, but every time the rise, they go to a new high water mark, every time they recede, they don't quite reach the previous low point.
Any of that make sense?
