Chart of the week: valuation as decisive factor

Valuation is often not the immediate trigger for a stock market turnaround. But it is a decisive factor in the amount of upward or downward potential for the market.

Re-rating

Since its low point in mid-June, the S&P 500 Index has risen 18 per cent. Over the same period, earnings per share rose by less than 2 per cent. There has thus been a considerable re-rating of equities over the past two months.
