Holiday Effects in the Chinese Stock Market

Various holiday effects are well documented for developed countries’ stock markets, typically showing abnormal returns around thanksgiving, Christmas, New Year, and Easter. Do similar effects exist in the Chinese stock market? In this post I’ll take a look at returns to the Shanghai Composite Index (SSECI) during the days surrounding the following holidays: New Year, Chinese New Year, Ching Ming Festival, Labor Day, Tuen Ng Festival, Mid-Autumn Festival. The index only has 22 years of history, so statistical significance is difficult to establish. Despite this, I believe the results are quite interesting1.

The charts require a bit of explanation: the error bars are 1.65 standard errors wide on each side. As such, if an error bar does not cross the x-axis, the returns on that day are statistically significantly different from zero at the 5% level (by way of a one-tailed t-test). The most interesting holidays are the New Year, Chinese New Year, and Ching Ming Festival, all of which have several days of quite high returns around them.

Bonus: Day of the Month Effects

Since we’re looking at seasonality effects, why not the day of the month effect as well? Using the walk-forward methodology as in my previous day of the month effect posts (U.S., Europe, Asia), here are the results for the Shanghai Composite Index:

Finally, the average returns for each day of the month over the last 5000 days:

The standard turn of the month effect seems to be present, but only for the first days of the month instead of the last and first days.

And with that, I’d like to you wish you all happy holidays! In eggnog veritas.
