Definition
The Hampton Effect refers to the drop in trading before the Labor Day long weekend, followed by an increase in trading volume as traders and investors return from the long weekend. The term refers to the tradition of many large Wall Street traders spending the last days of summer in the Hamptons, a traditional summer destination for New York City's elite.
Origin

This effect is a type of calendar effect based on statistical methods and current evidence, reflecting the seasonal changes in market participants' behavior.
Categories and Features
The Hampton Effect mainly manifests in two scenarios: firstly, the increase in trading volume can be positive, especially when trading is directed towards stabilizing overall returns; secondly, if portfolio managers decide to take profits rather than open or increase positions, the effect can be negative. This effect is characterized by its seasonality and cyclicality, typically emerging after the Labor Day long weekend.
Case Studies
A typical case is when a large investment firm increased its investments in tech stocks during the Hampton Effect period after Labor Day, resulting in significant portfolio gains. Another case involves a fund manager who chose to take profits after Labor Day, leading to short-term underperformance of the fund.

Investors applying the Hampton Effect might encounter issues such as misjudging market trends leading to investment losses, and over-reliance on seasonal effects while ignoring other market factors. A common misconception is that the Hampton Effect always results in positive market changes, overlooking its potential negative impacts.
