Merry Christmas -- North Texas -- DFW Area -- December 25, 2025

Locator49752MERRYCHRISTMAS.

Photo taken Christmas Eve, December 24, 2025. The New Yorker double issue: last issue of 2025, first issue of 2026. 

Unseasonably warm weather. 

81°F yesterday. Not quite as warm today but then should be in the 80s again tomorrow. 

Weather can be absolutely dreadful and freezing this time of year in Texas. But not this year.

Comparing Tickers -- Miscellaneous -- Rambling -- December 25, 2025

Locator49751INVESTING.

In general, what follows is accurate. There are many exceptions, qualifications, flip-flopping, modifications, etc, but generally this is what I would tell my broker as we begin the discussion.

I'm an investor, not a trader:

  • I have a "rolling" 30-year horizon.
  • I remain fully invested at all times (there are occasional exceptions).
  • I don't invest in bonds, only equities.

With regard to tickers:

  • one can cherry-pick all these charts, particularly "time-frames."
  • talk is cheap; tickers don't lie; put one's money where one's mouth is.

Time-frames:

  • I find anything under one year worthless, except:
    • when considering harvesting a tax loss; 
    • to see what analysts on CNBC are seeing;
  • when re-aligning my portfolio, the one-year ticker is most important
    • but even the one-year ticker is just one of many factors being considered.
  • I use the five-year time frame to see if my rules of investing are working:
    • at a minimum, the five year-return must be over 100%
    • Rule of 72: it takes nine years to double one's money at 8%
    • the average 20-year annual S&P 500 return runs between 9% and 11% (per AI prompt) with many caveats.

I honestly don't know what gets me more excited: all the oil activity, "tech"activity, HEB buildout, and Buc-ee's in Texas representing how fast that state's economy is growing OR following the "tech" story in general, unrelated to Texas. What's more exciting to me: tech or Texas? I honestly don't know.

Nvidia Acquires Groq -- A Manufacturer Of Integrated Circuits -- December 25, 2025

Locator49746GROQ

Again, we're talking about Groq, Inc., not Monsters, Inc (the movie) or Grok, the Musk xAI chatbot. Note the spelling of Groq

Chips are tracked at a tab at the top of the page.  

Note: this story is about "Groq," a chipmaking company. It is not about Grok, the xAI chatbot. 

Grok, the xAI chatbot: Grok is a generative artificial intelligence chatbot developed by xAI. 

It was launched in November 2023 by Elon Musk as an initiative based on the large language model of the same name. 

Groq, the AI company that builds hardware, or blades, or in this case, an "integrated circuit." 

Groq, Inc. is an American artificial intelligence (AI) company that builds an AI accelerator application-specific integrated circuit (ASIC) that they call the Language Processing Unit (LPU) and related hardware to accelerate the inference performance of AI workloads. 
Examples of the types of AI workloads that run on Groq's LPU are: large language models (LLMs),  image classification, and predictive analysis. 

AI prompt: what's the difference between the Xilinx field gated array (bought by AMD) and Groq's application-specific integrated circuit?  

Groq is headquartered in Mountain View, CA, and has offices in San Jose, CA; Liberty Lake, WA; Toronto, Canada; and, London, U.K. with remote employees throughout North America and Europe. 

Updates

December 26, 2025: this is a very, very interesting story. I assume that we're going to be hearing a lot about this "business deal" for quite some time. It seems to be a page from the playbook of BRK (Warren Buffett and Charlie Munger) -- "buying companies" but the companies continue to operate "entirely" autonomously but BRK provides financial, investing, and accounting support. Much could be said.  

This is the first full story from CNBC after this deal was announced. Link here. Nvidia has a market cap trending toward $5 trillion. The $20 billion earmarked for Grok amounts to 0.4% of $5 trillion. If my parents gave me $1 allowance when I was growing up, it would be like me paying half a cent for something I really, really liked and really, really wanted. It was not unusual for me to find a penny on the ground on any given day when I was growing up. 


AI prompt: Nvidia entered this agreement as a defensive move. What was the purpose of the defensive move?
