Lead–lag effect
From HandWiki
A lead–lag effect describes a relationship where one (leading) variable is cross-correlated with the value of another (lagging) variable that follows the leading variable's change at a later time.[2]
In nature and climate, bigger systems often display more pronounced lag effects. The Arctic Sea Ice minimum is on September 17, three months after the peak in daylight (sunshine) hours in the northern hemisphere, according to NASA.[3]
For example, economists have found that in some circumstances there is a lead-lag effect between large-capitalization and small-capitalization stock-portfolio prices.[4]
