Hamptons Effect

A decline in trading volume right before Labor Day weekend and an increase in volume right after the weekend

What is the Hamptons Effect?

The Hamptons Effect refers to a decline in trading volume right before Labor Day weekend and an increase in volume right after the weekend. The concept was first established because many investors on Wall Street leave on vacation for the Labor Day weekend and cease all trading activity.

The Labor Day weekend is the last long weekend of summer, so it is common for individuals to go on vacation. The Hamptons Effect got its name because the Hamptons is a popular vacation destination for individuals living in New York.

 

Hamptons Effect

 

Once investors are back from their vacation, they resume active trading. Assuming that such investors place trades in the market after the weekend, there will be an increase in trading volume right after Labor Day.

 

Significance of the Hamptons Effect

By understanding the Hamptons Effect, investors can take advantage of trading opportunities imposed by the Labor Day long weekend. Since there is a general trend that trading volume goes down before Labor Day and the volume goes back up after the weekend, investors may be able to benefit from this seasonal effect. Investors can analyze patterns in past datasets to determine stocks that can perform well during the Labor Day weekend, such as food stocks.

 

The Hamptons Effect vs. The Holiday Effect

Although the stock market is impacted by holidays and long weekends, the effect imposed by Labor Day weekend is different than other holidays. The holiday effect refers to the idea that there is a tendency for the stock market to gain and for trading volume to increase right before a holiday or long weekend.

The increase in stock prices is due to a high level of optimism right before a three-day holiday, followed by a decline in stock prices after the holiday is over. Stock prices often rise before the holidays because consumers tend to increase their spending during the holidays, especially Christmas.

The holiday effect also prevails for Thanksgiving in the United States, as Black Friday is the day after Thanksgiving, where many individuals enjoy significant shopping discounts. It is when consumer spending and retail sales increase significantly.

After the long weekend is over, the holiday effect leads to a tendency for the stock market to fall, as consumer activity goes back down to its initial level before the holiday. The holiday effect is different from the Hamptons Effect, as the Hamptons Effect refers to a reduction in trading activity right before Labor Day weekend.
