they put into perspective short term market movements, and in return for a few minutes of contemplation, you can avoid running around like a headless chicken or joining a herd of sheep heading into a pack of wolves. i also like following quote from paul ashworth, senior economist at capital economics, who said this week: 'what's going on in the stock markets is a reflection of the fact that investors are realizing non-financial profits are going to be absolutely whacked.'
what do they have to do with each other? profits have a direct impact on the p/e ratio (市盈率) of shares, which we can compare to its long term average.
this brings us back to my initial post on this blog, where i mentioned robert shiller's long term p/e chart. i've finally gotten hold of that data here below, and it's beautiful - there is no escaping a 130 year average. u.s. stocks are currently trading at an average p/e of 15 (below graph only shows data till august), and the long term average is 16. unfortunately, as the graph shows, after high peaks, the p/e will dive far underneath the average for quite some time - that's why it's called an average - ha!
now if a company's profits fall by 50%, but its share price stays the same, then the p/e ratio will have doubled. so we can make a quick and dirty assumption that profits will indeed be 'whacked', say by 50%, which they have done in the past after the popping of a bubble. we can also assume that the p/e ratio needs to come down to 7 to work its way back to the long term average, especially considering the extent to which it has gone and remained above average since 1990, then share prices have to fall to 25% of their current levels. that means the dow at 2000. i had previously ventured 4000 and it will probably bottom out somewhere in between, depending on how badly profits will be hurt.
feeling better yet?
