December tends to be quiet. Here's what investors need to know

Key Concepts

• Santa Claus Rally: A historical tendency for stock markets to rise during the last five trading days of December and the first two trading days of January.
• Seasonality: The tendency for financial markets to exhibit predictable patterns at certain times of the year.
• S&P 500 Index: A stock market index representing 500 of the largest publicly traded companies in the United States.
• VIX Volatility Index: A measure of the expected volatility of the S&P 500 index options over the next 30 days. It is often referred to as the "fear index."
• Median Performance: The middle value in a dataset, used here to represent the typical performance of the S&P 500 in different months.
• Post-Labor Day Dip: A historical pattern of a decline in stock prices following the Labor Day holiday in the US.
• Consolidation: A period where a stock or market trades within a narrow price range, indicating a lack of strong directional momentum.

December Trading Tendencies and S&P 500 Performance

The video discusses the typical trading patterns observed in December, a month often characterized by lower trading volume as the year concludes, leading into the Santa Claus rally.

• S&P 500 Monthly Performance:

  • Data going back to 1990, using median performance, shows September as the only consistently down month.
  • December's performance is described as being in the middle of the pack, with a positive tendency approximately 80% of the time.
  • November is highlighted as the best performing month of the year.

• Models for December Performance:

  • Model 1 (White Line): Represents actual market performance, showing a significant post-Labor Day dip followed by a strong rally.
  • Model 2 (Green Line): Based on the median performance since 1990, updated daily. This model suggests a gentle upward drift into the end of the year for December.
  • Model 3 (Based on Median Since 1928): This model, which only includes years matching specific day-of-the-week criteria, indicates a rally into late November, a dip in mid-December, and then a re-acceleration to new year-end highs.

VIX Volatility Index Trends

The video also examines the behavior of the VIX volatility index in relation to stock market performance.

• VIX Behavior: Generally, the VIX moves inversely to the stock market; it rises when stocks fall and vice versa.
• Current Year Performance (Green Line): The VIX experienced a notable spike post-Labor Day and smaller, muted spikes in October and a few weeks prior to the recording.
• Average VIX Performance (White Line): Since 1990, the VIX tends to peak in October and then gently declines into the end of the year as traders go on holiday, leading to lower volatility. A significant increase in VIX towards year-end would be unusual, though not unprecedented.

Key Arguments and Supporting Evidence

• Argument: December trading is generally positive with declining volatility.
  • Evidence: S&P 500 tends to be positive 80% of the time in December. The VIX typically trends downwards after October.
• Argument: When markets are up significantly coming into December, consolidation is likely in the first half of the month.
  • Evidence: This observation is attributed to Almanac Trader (Jeff Hirsh).
  • Caveat: Seasonality (historical tendencies) accounts for only about one-third of price action; catalysts and day-to-day events are more significant (at least two-thirds).
• Argument: Big sell-offs at year-end tend to occur at market bottoms and tops.
  • Evidence: This observation is also attributed to Almanac Trader.
• Argument: Small-cap stocks tend to outperform large-cap stocks (like the S&P 500) in December.
  • Evidence: This is mentioned as a tendency, though not elaborated with specific data in this segment.

Step-by-Step Process/Methodology

The video implicitly uses a historical data analysis approach to identify seasonal trading patterns:

1. Data Collection: Gathering historical performance data for the S&P 500 index and the VIX volatility index.
2. Statistical Analysis: Calculating median performance for each month of the year (S&P 500) and average trends (VIX).
3. Model Development: Creating different models to visualize and interpret historical data, including actual performance and median-based projections.
4. Pattern Identification: Identifying recurring tendencies, such as the post-Labor Day dip, year-end rallies, and seasonal VIX declines.
5. Correlation Analysis: Observing the relationship between stock market movements and VIX behavior.
6. Expert Attribution: Referencing insights from other market analysts (e.g., Almanac Trader) to support or complement findings.

Notable Quotes or Significant Statements

• "The only down month here, and this is going back to 1990, tends to be September." (Referring to S&P 500 median performance).
• "December... it's kind of in the middle of the pack, but nevertheless, it is positive, or it tends to be positive about 80% of the time." (Referring to S&P 500 median performance).
• "What we call seasonality those tendencies based on history well that only accounts for about onethird of price action reality you know what the catalysts are and what we face on a day-to-day basis that's at least at least 2/3." (Emphasizing the limited predictive power of seasonality alone).
• "So, having said all of that, let me go back to my chart here. Here are a few final thoughts on December trading." (Transitioning to concluding remarks).

Technical Terms and Concepts

• Santa Claus Rally: A specific period (last 5 trading days of December + first 2 of January) with a historical tendency for positive returns.
• Seasonality: Predictable patterns in market behavior tied to specific times of the year.
• Median: A statistical measure representing the middle value, used here to smooth out extreme data points and show typical performance.
• VIX: Volatility Index, a gauge of expected market turbulence.
• Consolidation: A trading range where prices move sideways, indicating indecision or a pause in a trend.
• Catalysts: Events or factors that trigger significant price movements in financial markets.

Logical Connections Between Sections

The video logically progresses from a general overview of December trading to specific data on the S&P 500 and VIX.

• The initial discussion of December's quiet nature and the Santa Claus rally sets the context.
• The S&P 500 monthly performance chart provides historical data to support the idea of a generally positive December.
• The different models for December performance offer nuanced perspectives on how the month might unfold, building on the general trend.
• The introduction of the VIX connects market sentiment and volatility to the trading environment, explaining why volatility typically decreases towards year-end.
• The final thoughts synthesize these observations, reiterating key tendencies and adding important caveats about the limitations of seasonality.

Data, Research Findings, or Statistics

• S&P 500 median performance data going back to 1990.
• September identified as the only consistently down month for the S&P 500 (based on median since 1990).
• December has a positive tendency approximately 80% of the time.
• November identified as the best performing month.
• The VIX average trend shows a decline into year-end after peaking in October.
• Seasonality is estimated to account for only about one-third of price action reality.

Conclusion/Synthesis

The video concludes that December trading typically exhibits positive tendencies for the S&P 500, with an 80% probability of gains, and a general decline in volatility as traders depart for holidays. While historical seasonality suggests a gentle upward drift or a pattern of mid-month dip followed by a year-end rally, it's crucial to remember that actual market catalysts and day-to-day events are far more influential. When markets have already experienced significant gains leading into December, consolidation in the first half of the month is a common observation, followed by a rally in the latter half. The Santa Claus rally, encompassing the last trading days of the year and the first two of the new year, is a specific historical phenomenon to watch for. Small-cap stocks are also noted to have a tendency to outperform large caps during this period.
