ecri wli again ....
well i had to check this to make sure i remembered correctly. this is just from a random search on google, so the particular month and data aren't important, just the wli components:
LEADING INDICATORS. Six of the ten indicators that make up the leading index increased in May. The positive contributors to the leading index in May - from largest to smallest - were interest rate spread, stock prices, index of consumer expectations, money supply, building permits, and manufacturers' new orders for nondefense capital goods. The negative contributors to the index from the largest negative contributor to the smallest - were vendor performance, average weekly manufacturing hours, and average weekly initial claims for unemployment insurance. Manufacturers' new orders for consumer goods and materials held steady for the month of May.
i recall folloiwing someone's data about 1 yr ago who used to recompute the wli's by including nasdaq data, so i'm pretty sure that "stock prices" here does not include nasdaq traded stocks.
