The Grok Portfolio White Paper

The Grok Portfolio follows an investment strategy that harnesses Grok’s analytical capabilities. By leveraging the latest advancements in artificial intelligence, the system provides systematically curated stock and sector selections. One of its standout features is using LLMs to derive investment scores that guide portfolio decisions.

Core Investment Rules

The portfolio uses a structured investment approach:

  • Composition: 15 individual assets that can include individual stocks or ETFs selected by Grok per the analysis process discussed below.
  • Holding Period: All assets are held for one month
  • Monthly Rebalancing: At month-end, the system conducts a complete analysis to select the top 15 assets and rebalances accordingly

AI-Powered Analysis System

A key distinction of our system is its method of keeping Grok current with market conditions. Since these models don't have real-time market knowledge, we provide them with the latest information through a systematic process:

The analysis integrates multiple data streams:

  1. Economic Context
  • Comprehensive AI-generated economic reports using the latest information about current market conditions and global events
  1. Company-Level Information
  • Financial ratios and metrics
  • Recent price movements and technical indicators
  • Current news and announcements

Scoring Methodology

The system employs carefully crafted prompts to ensure consistent and meaningful analysis. The prompts used to generate analyses of certain sectors and individual companies are disclosed in Exhibit 1.

Portfolio Construction Process

The system follows a systematic monthly process:

  1. Macro Analysis
  • Collection of economic indicators and trends
  • Analysis of significant global events
  • Generation of a comprehensive economic report
  1. Individual Stock Score
  • Analysis of S&P 500 companies
  • Integration of company-specific news and data
  • AI scores using firm-specific, sector, and macro information
  • Pre-selection of the top 30 companies based on the scores
  1. Portfolio Balance
  • Allocation is decided by LLMs to provide a diversified portfolio that does well under current conditions
  • Monthly rebalancing to maintain target allocations

Risk Management

The system incorporates several risk management features:

  • Diversification across multiple sectors and companies
  • Regular monthly rebalancing
  • Systematic scoring process
  • Multiple data sources

Conclusions

The Grok Portfolio represents a shift in investment management, placing AI at the core of the investment process. Through its analysis and the unparalleled capabilities of LLMs, it offers a systematic approach to navigating market complexities. While all investing carries inherent risks, the Grok Portfolio leverages cutting-edge technology to provide a disciplined, data-driven investment approach.

The system's success relies on three key elements:

  1. Systematic data collection and processing
  2. Sophisticated AI analysis through structured prompts
  3. Disciplined portfolio construction and rebalancing

This combination of technological innovation and investment discipline creates a unique approach to portfolio management that aims to capitalize on the analytical power of AI while maintaining rigorous investment principles.

Exhibit 2C

For the macro news, we use the past week’s news about general markets from the same sources as in Exhibit 2A. Additionally, we include current events from https://en.wikipedia.org/wiki/2025, https://en.wikipedia.org/wiki/2024_in_the_United_States

https://en.wikipedia.org/wiki/2025, https://en.wikipedia.org/wiki/2025_in_the_United_States

Exhibit 2D

For the macroeconomic events, we additionally use DeeperSearch from grok-3 with the following prompt:

Here are some events and context to update your knowledge information cutoff.

(Insert info here from previous steps)

Provide a complete expected timeline of the most important economic and political events for the next three months in the USA. Not only the scheduled events and known forecasts. Also, provide your best expectations about the realization of these events. Pay special attention to the next month. I also want a table with your forecast for interest rates, inflation, tariffs, and other economic events for the next month and quarter. Not only what analysts and the market expect. Provide your expectations based on your research and compare them with the market’s expectations.

Exhibit 2E

We then use the following prompt for the final allocation

Now, I want a 15-asset portfolio where we will invest for the next month (rebalancing in one month) in a table with weight, thesis, edge, and risk. Weight this portfolio to perform positively given the market conditions and to beat the S&P 500. We have the following reports for the stocks that were scored the highest:

(Insert top scores here)

However, we can also invest in most ETFs (except short, leveraged, or vol because of the monthly horizon), including but not limited to market, sectors, TIPS, and long and short-term bonds. You decide the weights do not have to include any or all of the stocks or instruments mentioned.

Remember, a 15-asset portfolio where we will invest for the next month (rebalancing in one month) in a table with weight, instrument type, thesis, edge, and risk. You can use both the stock info and your macro expectations, as well as reasoning about the future and markets.
