In this guide, we'll dive deep into the Momentum-Driven Event Trading strategy. This approach merges momentum analysis with real-time news sentiment to pinpoint short-term market opportunities, aiming for potential profit. Let's explore the intricacies of this strategy and learn how to execute it effectively.

The Philosophy of Momentum

Momentum trading is predicated on the Newtonian concept that an object in motion tends to stay in motion unless acted upon by an external force. In the stock market, this translates to the idea that stocks moving in a certain direction are likely to continue their trajectory.

Momentum trading also has a psychological dimension. It leverages the herd mentality, where investors tend to follow the crowd. By identifying the direction in which the majority of market participants are moving, momentum traders aim to enter and exit positions before the trend reverses, thus maximizing gains and minimizing losses.

In practice, momentum trading requires constant vigilance and a willingness to act swiftly. Traders must be prepared to adjust their positions as market conditions change and must have a clear understanding of when to cut losses and take profits. The success of momentum trading lies in the trader’s ability to accurately read market signals and execute trades that align with the prevailing trend.

Strategy Rationale

The market is not just a collection of numbers; it is a dynamic ecosystem driven by human emotions, perceptions, and reactions. When a stock begins to move, whether upward or downward, it attracts attention. This attention, fueled by investor sentiment, can create a self-reinforcing cycle where the perception of value drives actual value.

In Momentum-Driven Event Trading, news plays a pivotal role. It acts as a catalyst that can accelerate the momentum of a security. Positive news can lead to increased buying pressure, while negative news can result in selling pressure. The strategy hinges on the ability to quickly analyze news sentiment and integrate it with momentum indicators to make informed trading decisions.

By combining momentum analysis with live news sentiment, traders can identify stocks that are poised for short-term movement, allowing them to enter and exit trades with precision.

Why Momentum-Driven Event Trading?

This strategy leverages two powerful forces in the market: momentum and news events. Momentum refers to the tendency of a stock's price to continue moving in the same direction it has been moving recently. News events, both positive and negative, can significantly impact stock prices. By combining these factors, we aim to identify stocks with high momentum that are likely to experience further price movement due to positive news sentiment.

Imagine a stock experiences a surge in positive news coverage about a new product launch. This positive sentiment could trigger a momentum algorithm to generate buy signals, anticipating further price increases due to heightened investor interest.

Preparing Momentum Data

Now, let's dive into the data preparation process for this strategy. Here's a breakdown of the steps involved:

Universe Selection:  First, we need to define a universe of stocks we'll analyze. This could be a specific sector, industry, or a broader market index.

Return Data Collection:  Collect the historical price data for all the stocks in your chosen universe. This data should ideally span the past 6 to 12 months.

Intermediate Momentum Calculation:  To identify stocks with sustained momentum, we'll calculate the intermediate momentum. This involves calculating the cumulative return for the chosen period (e.g., 6 - 12 months) but excluding the most recent month's return.

For example, if you're using 12-month data, calculate the total return from January to November and exclude December's return.

Gross Return Calculation:  Convert the monthly returns from a percentage to a decimal value. To do this, simply divide the monthly return by 100 and add 1. (e.g., If a monthly return is 5%, convert it to 0.05 + 1 = 1.05)

Momentum Score Calculation: To arrive at a momentum score, multiply all the gross monthly returns within the chosen period (6 or 12 months) and subtract 1 from the final product.

Real Life Example

Let's say a stock has the following monthly returns for the past 6 months:

• Month 1: 3%

• Month 2: 5%

• Month 3: -2%

• Month 4: 8%

• Month 5: 4%

• Month 6: 1%

Following the steps above:

• Gross monthly returns:

  • Month 1: 1.03

  • Month 2: 1.05

  • Month 3: 0.98 (since it's negative)

  • Month 4: 1.08

  • Month 5: 1.04

  • Month 6: 1.01

• Momentum Score: (1.03*1.05 0.98*1.08 *1.04 * 1.01) - 1 ≈ 0.11 ≈ 11%

A higher momentum score indicates stronger momentum.

Before proceeding, can you explain the rationale behind excluding the most recent month's return from the intermediate momentum calculation? (Think about potential biases)

Event Data Preparation with ChatGPT API

Now that we have the momentum scores for our chosen stocks, let's incorporate news sentiment analysis. Here's where the ChatGPT API comes into play:

Live News Feed:  ConsX provides access to live news feeds for all the stocks in your universe. This ensures you're working with the latest information.

Sentiment Analysis:  ChatGPT API, a powerful language processing tool, can be used to analyze the sentiment of the news articles associated with each stock. It can categorize the sentiment as positive, negative, or neutral.

Assigning a News Score:  Based on the sentiment analysis, assign a score to each stock. Here's a possible scoring system:

• Positive Sentiment: 70 - 100 points

• Neutral Sentiment: 40 - 69 points

• Negative Sentiment: 0 - 39 points

Based on the momentum and news scores we calculated, here's how we'll formulate our trading strategy:

Long Positions:

We'll target stocks with the highest momentum scores (top 5) and the highest news sentiment scores (above 70). These stocks exhibit strong upward momentum and positive news catalysts, potentially leading to further price gains.

Short Positions:

We'll identify stocks with the lowest momentum scores (bottom 5) and the lowest news sentiment scores (below 40). These stocks display weak momentum and negative news sentiment, suggesting potential price declines.

Trade Duration:

This strategy is designed for short-term holdings. We recommend holding these positions for a period ranging from 1 week to 3 months. Remember, momentum-driven strategies aim to capitalize on short-term market movements.

Example:

Let's assume you've analyzed 50 stocks in the technology sector and calculated their momentum and news scores. Here's a simplified example of how you might identify potential trades:

• Long Positions:

  • TechCompanyA: Momentum Score (0.25 or 25%), News Score (85)

  • TechCompanyB: Momentum Score (0.18 or 18%), News Score (78)

  • (3 more companies with similar scores)

• Short Positions:

  • TechCompanyX: Momentum Score (-0.02 or -2%), News Score (25)

  • TechCompanyY: Momentum Score (-0.05 or -5%), News Score (18)

  • (3 more companies with similar scores)

This is a simplified example. In reality, your analysis will involve a larger pool of stocks and potentially more complex scoring systems.
