Economist W.S. Jevons astounded the British Association for the Advancement of Science in 1878 by postulating that ups and downs in the economy were caused by sunspot cycles, which he said governed agricultural cycles.

Yet countless Americans have their personal systems for handicapping the economy. Their idiosyncratic indicators are sometimes as reliable as the official measures.
