Dec 15, 2025 | Stock Market Outlook

Weakness Dips LikelyPrior Trading Day Summary

On Fri Dec 12 stocks opened higher and then fell throughout the day. The SPX high for the day was 6899 and the low 6801 for a wide move intraday. The close was down 73 points to 6827.

Volume on New York was 5 billion, 100 million less that Thursday’s volume. 65% of all stocks were falling. For the week, the SPX lost just 43 points.

The NASDAQ fell more thanks to all the tech names that were declining. The index lost 398  points to close at 23,195. Volume was 9 billion, the highest single day since Nov 24. 67% of all stocks were falling on Friday.

For the week, the NASDAQ lost 383 points.

While historically the first two weeks of December tend to be weaker than the final three weeks, the technical indicators showed growing weakness on Friday that investors should review.

Let’s review the closing technical indicators from Fri Dec 12 2025 to see what we should expect for Mon Dec 15 2025.


Stock Market Outlook: SPX Closing Chart For Fri Dec 12 2025 

The index closed above all major moving averages but below the Upper Bollinger Band. The SPX is trying to break free of the sideways trend but was unable to do so on Friday.

The closing candlestick is bearish with slight shadows indicating weakness and probable dips on Monday.

The 21 day moving average is falling and closed lower at 6771. The 21 day will fall below the 50 day if Monday ends negative. This will be a major down signal if it occurs.

The 50 day moving average is rising and closed at 6761 which is bullish.

The 100 day moving average is rising and closed at 6603 which is bullish.

The 200 day moving average is rising and closed at 6355 which is bullish.

The Lower Bollinger Band is falling further below the 100 day moving average. This is bearish. The Upper Bollinger Band is turning lower which is also bearish.

By the close on Friday there are more bearish signals than bullish.

SPX Stock Market Outlook review of Fri Dec 12 2025


Stock Market Outlook: Technical Indicators Review

Momentum: Momentum is falling and only slightly positive which is bearish.

  • Settings: For momentum I use a 10 period when studying market direction.
MACD Histogram: MACD (Moving Averages Convergence / Divergence) issued an up signal on Fri Nov 28. On Fri Dec 12 2025 the up signal lost a a large amount of strength.

  • Settings: For MACD Histogram, I am using the Fast Points set at 13, Slow Points at 26 and Smoothing at 9.
Ultimate Oscillator: The Ultimate Oscillator is falling.

  • Settings: The Ultimate Oscillator settings are: Period 1 is 5, Period 2 is 10, Period 3 is 15, Factor 1 is 4, Factor 2 is 2 and Factor 3 is 1. These are not the default settings but are the settings I use with the S&P 500 chart set for 1 to 3 months.
Slow Stochastic: The Slow Stochastic has a down signal in place and is overbought

  • Settings: For the Slow Stochastic I use the K period of 14 and D period of 3. The Slow Stochastic tries to predict the market direction further out than just one day.
Relative Strength Index: The RSI signal is falling sharply.

  • Settings: The relative strength index is set for a period of 5 which gives it 5 days of market movement to monitor. It is often the first indicator to show an overbought or oversold signal.
Rate of Change: The rate of change is falling signaling lower day should be expected for Monday.

Settings: Rate Of Change is set for a 21 period. This indicator looks back 21 days and compares price action from the past to the present. With the Rate Of Change, prices are rising when signals are positive. Conversely, prices are falling when signals are negative. As an advance rises, the Rate Of Change signal should also rise higher, otherwise the rally is suspect. A decline should see the Rate Of Change fall into negative signals. The more negative the signals the stronger the decline.

Stock Market Outlook for Mon Dec 15 2025 

Monday starts with many bearish signals which are growing in strength. The Bollinger Bands are turning down indicating a lower move is possibly building.

Overall though the losses last week were minor and historically the first two weeks of December have been weak. The remaining three weeks historically are stronger.

Monday though looks weak. We could see a bounce attempt at the open but then more weakness as investors will continue to sell tech names lower to start the week.


Potential Economic and Political Market Moving Events

Monday:

8:30 Empire state manufacturing survey is estimated to fall to 10.0 from 18.7 prior

10:00 Home builder confidence index is estimated unchanged at 38
