RAM AI'S RESEARCH
RAM AI’s research drives our investment decisions and performance.
RAM AI’s researchers relentlessly explore new ways of extracting information from data to uncover new sources of return, increase diversification and improve liquidity. Our conviction is that ongoing research and a disciplined approach to investment help take advantage of market inefficiencies in a continuous manner, technological advancements being leveraged to reveal the predictive power of the exponentially-growing volume of information at our disposal.
SYSTEMATIC MARKET NEUTRAL: THE BENEFITS OF DIVERSIFYING FREQUENCIES
At RAM AI, we have developed a deep learning framework to forecast stock returns based on a wide array of time-series inputs. This paper illustrates how shorter-term strategies have attractive standalone characteristics and benefit lower-frequency books. Read full paper here.
TO INVEST OR NOT TO INVEST? CAPITALISING R&D EXPENSES TO INCREASE VALUATION ACCURACY
The profits a firm generates can either be distributed to its shareholders through dividends/share buybacks, pay back some of its debt or be used to invest. A company invests in its future organic growth either through Research and Development (R&D) or by engaging in Capital Expenditures (Capex). In a previous research paper, we studied the effect of Capex announcements on stock returns. The present document analyses R&D activity and its impact on company fundamentals. Read full paper here.
TO INVEST OR NOT TO INVEST? THE EFFECT OF CAPEX ANNOUNCEMENTS
The profits a firm generates can either be distributed to its shareholders through dividends/share buybacks, reduce its debt or be used to invest. A company invests in its future organic growth either through Research and Development or by engaging in Capital Expenditures (Capex). As of January 2021, the net Capital Expenditure on sales ratio reached 2.54% for US companies. Read full paper here.
ON THE ROAD TO NET-ZERO: A DECARBONISED INVESTABLE UNIVERSE
RAM AI joined the Net-Zero Asset Manager’s initiative in 2021 and committed to meeting Net-Zero emissions by 2050. We also committed to interim goals with a carbon emission intensity reduction of 33% by 2025 and 50% by 2030. Three complementary approaches have been deployed to meet those targets:
- Climate risk mitigation through universe construction
- Climate opportunity integration
- Active ownership
In this paper, we will focus on universe construction and analyse how reducing the carbon footprint impacts financial performances and style biases. Read full paper here.
BEYOND ESG RATING: THE REAL IMPACT OF GOOD GOVERNANCE
The Sustainable Finance Disclosure Regulation (SFDR) is a European regulation introduced in 2019 and applicable from 10th March 2021 to improve transparency in the market for sustainable investment products and in sustainability claims made by financial market participants, and prevent greenwashing. In this paper, we analyse the impact an SFDR governance framework can have on return and style biases. Read full paper here.
AI FOR ESG INTEGRATION: TRAINING MACHINES TO PREDICT SUSTAINABLE ALPHA
Over recent years, data measuring firms’ sustainability characteristics has proliferated. An important challenge that investment managers encounter is the combination of ESG and traditional factors such as value, growth and momentum, which is crucial for an optimal stock selection and portfolio construction process. RAM AI’s systematic equity team has developed a deep learning framework that models the interaction among different input features. In this paper, we will evaluate the efficacy of this framework when tuned to combine ESG and traditional factors for a stock return prediction task. Read full paper here.
A DEEP LEARNING FRAMEWORK FOR CLIMATE RESPONSIBLE INVESTMENT
Incorporating climate considerations into portfolio analysis and systematic investments has drawn numerous attention recently. It is motivated by the pursuit of sustainable investing for a low-carbon transition. In this paper, we propose to integrate both structured and unstructured climate-related data into quantitative investing for stock markets, e.g. carbon emission scores and climate events from news flows. We develop a deep learning framework to consume these data for assessing climate-related opportunities and the risk of stocks in the investing universe. Experimental evaluation on real data demonstrates the low-carbon intensity of the constructed portfolio as well as decent investing return. Read full paper here.
A LEADING APPROACH TO ESG INTEGRATION
The rapid growth of ESG data in recent years makes it a compelling new dimension to the investment process, but integrating ESG presents a wide array of challenges, from noise filtering to hidden biases. In this paper we introduce some of the shortcomings of ESG data, as well as the value-added ESG inputs can bring into a stock selection process. Read full paper here.
CARBON OFFSET MARKET REVIEW
Carbon Credit is a generic term for any tradable certificate representing a certain amount of carbon emissions. A government, corporate or any individual wanting to offset a defined amount of carbon emitted by their activities, can buy credits for a specific amount of CO² to balance their emissions.

GO BEYOND SENTIMENT: STOCK PREDICTION ENHANCED WITH FINANCIAL NEWS
Nowadays, large language models are among the most impactful natural language processing techniques and have gained popularity in various applications, such as machine translation, language understanding, etc. These language models can be fine-tuned on domain-specific datasets to fit into the corresponding applications. In this paper, we will study the effect of financial news articles’ sentiments and text embeddings on predicting stock returns. Our in-house developed deep learning framework is able to model interactions between different input features and facilitates the comparison of feature combinations. Read full paper here.
MACHINE LEARNING: FINANCIAL DATA TAKES A NEW DIMENSION
In this paper we will look at the growing popularity of artificial intelligence and the potential for finance to prosper from machine learning implementations. As technology continues to push the boundaries of our imagination, new dimensions will undoubtedly emerge over time. Read full paper here.
UNLOCKING THE SECRETS IN SEMANTICS
Traditional market and factor datasets are typically structured in numerical terms in a form that can be digested by statistical models. Machine Learning can help deal with the abundance of rich textual data gleaned from financial news, earnings reports, and transcripts and their correlation to markets, currently, less exploited by quantitative managers. We take a dive into NLP techniques and their integration methods at RAM AI in the following Q&A. Read Q&A with RAM’s Data Scientist, Tian Guo.
PREDICTING THE IMPACT OF ESG NEWS WITH DEEP LEARNING – ESG2RISK
Incorporating environmental, social, and governance (ESG) considerations into systematic investments have drawn numerous attention recently. In this paper, we focus on the ESG events in financial news flow and explore the predictive power of ESG related financial news on stock volatility. In particular, we develop a pipeline of ESG news extraction, news representations, and Bayesian inference of deep learning models. Experimental evaluation on real data and different markets demonstrates the superior predicting performance as well as the relation of high volatility prediction to stocks with potentially high risk and low return. It also shows the prospect of the proposed pipeline as a flexible predicting framework for various textual data and target variables. Read full paper here.
