This website uses a new term "December/January Effect" to refer generally to interesting results re: small-cap stock performance near year-end. Investors have used the term "January effect" to refer to the phenomenon in which small-cap securities often have had higher rates of return than large-cap stocks in the January months in the 20th Century.
Perhaps because the "January Effect" has been so well publicized over the past decade or two, the January Effect has been well-anticipated and the Russell 2000 outperformed the Russell 1000 by more than five percentage points in the three Decembers from 1999 through 2001. Some observers now believe that that the January Effect might have disappeared for most small-cap stocks, but at least one writer has suggested that the phenomenon might still persist for very small microcap stocks.
The CBOE is the only exchange where investors can access options on all these indexes (and dozens more index options) to help manage their portfolios:
The "January effect" has been used to refer to the phenomenon in which small-cap securities often have had higher rates of return in past Januarys than large-cap stocks. The effect was first suggested in 1942, and widely publicized in the past 25 years by scholarly articles and a popular book entitled The Incredible January Effect: The Stock Market's Unsolved Mystery, by Robert A. Haugen and Josef Lakonishok. Perhaps due in part to publicity and anticipation of the effect, the January effect has weakened in recent years.
There are a number of theories as to why the January effect has occurred. Some people speculate that it may be related to the many year-end research reports on the small-cap market, which can make these stocks look like attractive places to put money. Another theory says that investors who need cash for the holiday season will sell some holdings; bargain hunters then swoop in to buy the sold-off shares. Others believe the effect may be related to tax-motivated selling and buying -- fund managers might rush to buy back all those money-losing stocks they had previously sold to meet the tax-loss deadline. See the bibliography below for more details.
One recent article suggested that:
1. The January effect remains either dead or dormant for all but the smallest firms.
2. The January effect in these stocks survives even after we account for a large list of risk factors.
3. While it hasn't been figured out how to effectively exploit this little anomaly yet, there still appears to be time."

The graph below shows that the stocks in the 10th decile (with very small capitalizations) outperformed the 1st decile (very-large-capitalization) stocks in 70 of the 77 Januarys from 1926 to 2002.
From 1926 through 2002, the smallest 10% of all stocks (or "10th decile") beat the 1st decile stocks by an average of 9.35 percentage points in the month of January.
If you have an interest in microcap stocks, you might explore the use of the new CBOE options on the iShares Russell Microcap Index Fund (IWC).
