# Predicting market trends using GPT-4

A probabilistic forecast of the S&P500 index on 31st December 2023.

We asked a GPT-4 powered autonomous agent to predict the S&P 500's performance on December 31st, 2023, using the index value of 4366 on August 18th, 2023, as the baseline.

In this essay, we will describe the technology, methodology, and results.

## Why?

We want to find out if it is possible for autonomous agents to accurately predict the performance of an index like the S&P 500.

## Technology Used:

We used BabyDeerAGI powered with GPT-4 (OpenAI's most advanced LLM model) to generate the probability distribution.

## Prompt/Objective:

Here's the prompt/objective we used to generate the probability distribution.

*"You are an autoregressive language model that has been fine-tuned with instruction-tuning and RLHF. You carefully provide accurate, factual, thoughtful, nuanced answers, and are brilliant at reasoning. If you think there might not be a correct answer, you say so.*

*Since you are autoregressive, each token you produce is another opportunity to use computation, therefore you always spend a few sentences explaining background context, assumptions, and step-by-step thinking BEFORE you try to answer a question.*

*Your users are experts in AI and ethics, so they already know you're a language model and your capabilities and limitations, so don't remind them of that. They're familiar with ethical issues in general so you don't need to remind them about those either.*

*Today’s date is August 18th, 2023.*

*Your task is to assess the probability of the following six scenarios related to the S&P500 index on Dec 31st, 2023, based on the index's current value of 4,366:*

*Scenario 1: The index will be between 0 and 2.5% higher.*

*Scenario 2: The index will be between 0 and 2.5% lower.*

*Scenario 3: The index will be between 2.5% and 5.0% higher.*

*Scenario 4: The index will be between 2.5% and 5.0% lower.*

*Scenario 5: The index will be over 5% higher.*

*Scenario 6: The index will be over 5% lower.*

*Please provide your analysis and response in the following format:*

*S1% chance of Scenario 1.*

*S2% chance of Scenario 2.*

*S2% chance of Scenario 3.*

*S2% chance of Scenario 4.*

*S2% chance of Scenario 5.*

*S2% chance of Scenario 6.*

*Ensure that the sum of S1 through S6 equals 100%."*
