The time evolution of many economics variables exhibits a wave-like behavior with local maxima (peaks) followed by local minima (troughs).

The drawdown duration is the length of any peak to peak period, or the time between new equity highs. The max drawdown duration is the worst (the maximum/longest) amount of time an investment has seen between peaks (equity highs). Many assume Max DD Duration is the length of time between new highs during which the Max DD (magnitude) occurred.
An expansion is the period from a trough to a peak and a recession as the period from a peak to a trough. The NBER identifies a recession as "a significant decline in economic activity spread across the economy, lasting more than a few months, normally visible in real GDP, real income, employment, industrial production".

Peak demand on an electrical grid is the highest electrical power demand that has occurred over a specified time period (Gönen 2008). Peak demand is typically characterized as annual, daily or seasonal and has the unit of power. [ 1 ]
"Hubbert's peak" can refer to the peaking of production in a particular area, which has now been observed for many fields and regions. Hubbert's peak was thought to have been achieved in the United States contiguous 48 states (that is, excluding Alaska and Hawaii) in the early 1970s. Oil production peaked at 10.2 million barrels (1.62 × 10 ^ 6 m 3) per day in 1970 and then dec
Peak and off-peak pricing is a form of price discrimination where the price variation is due to some type of seasonal factor. The objective of peak and off peak pricing is to use prices to even out peaks and troughs in demand. Peak and off-peak pricing is widely used in tourism, travel and also in utilities such as electricity providers.
