Sentiment Analysis Applied to Finance

Sentiment Analysis Applied to Finance

Sentiment Analysis has developed as a technology that applies machine learning and makes a rapid assessment of the sentiments expressed in news releases. News (events) move the market and are measured quantitatively. Analysts and investors digest financial news and their perceptions impact the market and move stock prices. This conference presents the current state of the art in this fast-emerging field. The conference also presents the current state of knowledge in the application of Sentiment Analysis to the respective models of trading, fund management and risk control.  Major news (meta) data suppliers such as Bloomberg, Thomson Reuters, Dow Jones, RavenPack and MarketPsych have committed their participation.  . Case studies by investment banks, proprietary trading houses and financial analytics providers are under discussion; further such contributions are solicited.  Leading academics, thought leaders and researchers from Europe, UK and USA have agreed to contribute and participate in the conference and the workshops.

OptiRisk sponsored Big Data Conference 2013 at UNICOM Seminars

Just giving a quick heads up of OptiRisk’s latest activities. OptiRisk Systems sponsored and exhibited at “Big Data in the Context of Financial Analytics & Social Media: B2B & B2C Infonomics” on 5 December.

Let me give some background to Big Data. Nowadays the Big Data word is buzzing around in nearly all organisations, and there is a pressing need to implement big data strategies. Data in the cloud provides the opportunity to further explore Big Data analytics and helps them to decide which data they should save forever and which they should throw away. 

Big Data in the Context of Financial Analytics & Social Media: B2B & B2C Infonomics” conference was organised by UNICOM Seminars on 5 December at Novotel London West. Many renowned speakers presented their experience of Big Data in the conference.

The conference was welcomed and introduced by Prof. Gautam Mitra, CEO of OptiRisk Systems. Professor David J Hand, Chief Scientific Advisor at Winton Capital Management and an emeritus Professor of Mathematics at Imperial College London, was the opening keynote speaker, who presented “Big Data: less than meets the eye?” He spoke of the potential benefits of Big Data, Open Data as well as the rules. The audience liked the summary of his talk that  “no one actually wants data; they want the answers which can be extracted from data”.

David’s talk was followed by Mike Ferguson, Intelligent Business Strategies, who gave a presentation on “Big Data: Multiplatform Analytics” and explained the critical factors of big data. Dai Clegg from Acunu presented “Rise of Real Time Analytics: the second wave of Big Data”. Other presenters were Daniel Roberts from MongoDB, Charlie Hull from Flax, Cynan Rhodes & Clive Shirley from FSWire and the last presenter Federico Alberto Pozzi joined the conference from University of Milano-Bicocca in Italy.

This conference was organised alongside “Adopting Open Source Software within the Corporate ICT Strategy”. There was a combined panel session: Open Source Software & Proprietary Software: Identifying the winning strategy” across the both conferences. This panel was moderated and chaired by Prof. Mitra and panellists included Daniel Roberts, MongoDB; Clive Shirley, FSWire; Charlie Hull, Flax; Matt Hamailton, Netsight: Hugo Trippaers, Schuberg Philis.

OptiRisk Systems thanked UNICOM for organising this event and for bringing together leading finance professionals in the sector of big data. We would welcome your feedback of this blog.

Adopting Open Source Software within the Corporate ICT Strategy

Open Source Software has facilitated innovation in the market place. It is already a backbone of cloud innovation and has hastened the delivery of social solutions in Customer Relationship Management (CRM) and provided applications for development in many industries.

Most Open Source projects are hosted by non-profit organisations. Many of them have the word “foundation” in their name – Mozilla Foundation, Document Foundation, Apache Software Foundation and collectively they are known as “foundations”. Business leaders use to discuss matters of mutual interest – called Floss (Free/Liber and Open Source Software). The important aspect of all Floss licensing is to grant a license that gives the same rights and freedoms to everyone in the public – individuals, non-profit and profit organisations. Government agencies are increasingly turning to Open Source technologies in the wake of shrinking budgets.

Enterprises are dealing with exploding levels of business events and associated data. In order to stay competitive and meet customer expectations, the companies need to embrace new standard for communication on the internet and Open Source has made it easy for them. There is licensing strategy for Open Source Software. Open Source Software (OSS) licensing permits businesses to open up their projects to the public access and they can submit, add, change, repair, or to build on top of the existing software code. Many organizations or developers do not have a positive understanding of the differences between the various OSS licenses and how to go about selecting one that fits closely with their software project, nor are they well-informed of how they want the project to be open for public involvement.

UNICOM is organising a conference “Adopting Open Source Software within the corporate ICT strategy” on 5 December. This conference sets out to attract the best of breed open source proponents and those government departments, NGOs and multinationals who see the growing market strength of the OSS movement and plan to build this into their formal ICT strategy.

Sentiment Analysis Applied to Finance

The growing importance of Sentiment Analysis applied to finance bring forth many questions to minds like why “Sentiment Analysis is important and why is online media and social media important to look at? Sentiment analysis tools automatically extract opinions, emotions and sentiments in text. It also allows individuals to get an opinion on reviews on a global scale. In terms of artificial intelligence, sentiment analysis uses a lot of mathematical calculation to determine whether the reviews capture positive or negative opinions.

Social media has created a new world of venting customer voice. Sentiment analysis offers organisations the ability to observe the different social media sites in real time and then act accordingly. Twitter is considered to be the ocean of sentiment data. Anyone can extract the data easily by searching on hash tags (#) on twitter.

I came across Michelle Price’s article “Taking sentiment analysis beyond trading” in Financial News on 3 December 2012. She said, “When the financial industry first embraced sentiment analysis of news and social media sites, it was chiefly regarded as a means of making money”.  She also referred to Richard Brown, head of quantitative and event-driven trading solutions at Thomson Reuters, saying: “In terms of the value from social media sites, we’re at the tip of the iceberg at what the industry can achieve.

 Sentiment analysis has developed as a technology that applies machine learning to make a rapid assessment of the sentiments expressed in news releases. Investment managers, funds managers, marketing managers, and equity investors are the direct beneficiaries of sentiment analysis technology.

News events impact market sentiment and financial news moves stock prices through a direct impact on a company’s expected future cash flows. Based on this concept UNICOM in collaboration with OptiRisk Systems is organizing a conference “Sentiment Analysis Applied to Finance”. This conference presents the current state of the art in the application of Sentiment Analysis to the respective models of trading, fund management and risk control. The conference presents in a summary form the research results in this fast-emerging field.

 Many leading technical specialists will participate in this conference and present overview talks, case studies of their fields and experiences.

UNICOM and OptiRisk have been working recently with a number of partner institutions who are highly regarded in the area of finance: PRMIA, the 14 – 10 Club @ the Royal Institution (The 14-10 Club is exclusively for finance professionals. It was set up in 2011 and is sponsored by Investment Banks and leading hedge funds). On the commercial side they also have partnership with The Mankoff Company < New York, USA >. In partnership with these professional institutions, UNICOM and OptiRisk are organising the “Sentiment Analysis Applied to Finance” conference in June/July to attract a wide audience.

OptiRisk Systems, in collaboration with UNICOM seminars, ran a very successful workshop “Finance with R” on 6 – 7 November 2012.

A significant number of people who were unable to attend the workshop requested us to repeat the workshop. We are delighted to advise that the “Finance with R” workshop will be running again on 5 – 6 March 2013. We hope anyone who have missed the November workshop will be able to attend. It’s a great opportunity to learn about using R in finance sector.

We have received positive feedback from the delegates on the recently concluded workshop. Attendees especially appreciated the topic “how to use R in Finance – Portfolio Optimisaiton and VaR”. Among the participants were Fitch Rating, HSBC, RMC, Solo Capital, UCL finance researchers, many PRMIA members and others.

IBM Optimisation Forum

OptiRisk Systems in association with IBM UK and UNICOM Seminars, hosted a gala event on “Optimisation in the Financial Services Sector” On November 13, 2012 at the IBM South Bank Premises.

The event had participation from over 50 delegates representing Financial Firms, Asset Management Firms, Investment Banks as well as Academics.

The event participation had an interesting blend of industry and academia with reputed speakers like David Jessop (Head of Quantitative Research, UBS), Gautam Mitra (MD OptiRisk Systems, Professor Emeritus Brunel University) and Nalan Gulpinar (Professor, WBS) presenting.

The forum presented some cutting edge topics and challenged the thinking  of leading practitioners in using optimisation technologies in Asset Management and Portfolio Optimisation.

With the economy on slow road to recovery, and financial firms desperate to look for new ways to better manage their portfolios, this event was of paramount importance.

We do hope that in the coming months and years, some of these leading research outputs will be exploited commercially as banks will gradually identify the need to look for alternative ways to manage their risks

Here are the presentations from the forum:

News Analytics: It’s about more than just fundamentals

In the first edition of Short n’ Sharpe, I would like to focus on the significance of News Analytics – a study of how news and information impacts the price formation, volatility and liquidity of a security or index (Mitra, OptiRisk, 2011) – in the context of financial markets and “tactical” (i.e. short-term, time-sensitive) portfolio allocations. In the process, we will also observe the crucial role of cognitive biases – apparently one of the principal deficiencies of the Efficient Market Hypothesis (EMH) – in the investment process, which in turn makes quantifying the extent of sentiment/momentum that much more crucial.

One might ask, is there a compelling reason to believe that systematic news analysis could help active market participants[1] effectively capture alpha[2]? Evidence suggests that the answer to that question may well lie in the affirmative; the answer is, in fact, embedded in frequent deviations of market valuations from underlying fundamentals until the news data-points are digested and reflected in asset prices. Put another way, it is through news analysis that we endeavor to disprove, albeit primarily in the near term, one of the EMH’s primary contentions – that “market participants [will] not be able to systematically profit from market inefficiencies” (The Efficient Market Hypothesis, Wikipedia).  Let’s consider a recent case where monitoring news-flow consistently and analyzing it methodically might have helped investors beat the market – that of how the politically controversial proposal of Foreign Direct Investment (FDI) in India’s multi-brand retail sector affected the share price performance and tradability of the country’s flagship department store owner, Pantaloon Retail.

I first go back to October 18th, 2011. This is when the Business Standard first reported the possibility of an FDI bill being introduced in Parliament as a standalone measure (Decision on multi-brand retail by year end, Business Standard ), thereby marking the inception of persistent speculation and news-flow around this issue. The proposal would be immensely positive for Pantaloon whose balance sheet held US$1bn in cumulative debt. As expected, trading volumes on Pantaloon’s stock spiked up as did its Implied Volatility, as shown in the charts below:

Pantaloon Retail – Share Price Action + Trading Volumes 2011 (Source: Bloomberg):


Pantaloon Retail – Implied Volatility (Source: Bloomberg):

Interestingly, however, despite the fundamentally positive nature of the proposal for Pantaloon’s balance sheet (and consequently its equity value), the stock collapsed by 19.82%. Why the divergence? This is where cognitive bias comes into play. Investors felt little confidence that the FDI bill, a standalone proposal at the time and a risk to India’s multiple small mom-and-pop shops, would be politically controversial and hence get opposed aggressively by socialist politicians in Parliament, then in session. Needless to say, the crowd was right. The bill was quashed and Pantaloon’s stock fell further post the revocation (FDI in retail – Opposition to corner govt in Parliament, Times of India). The underlying sentiment from a seemingly positive development, well, wasn’t as positive!

The bottom-line? An amalgamation of headline news and market/investor sentiment had impacted Pantaloon’s stock price, volatility and liquidity. As speculation surrounding this issue stayed elevated, so did implied volatility levels as indicated in the chart above.

Let us now fast-forward to September 14th, 2012. This is when the Cabinet finally approved the same measure along with many others. With Parliament not in session and the government’s principal opposing ally no longer a part of its coalition, there was little room for pushback and the bill was ratified into law immediately. Once again, a constructive outcome for Pantaloon, which now holds US$1.2bn of cumulative debt on its balance sheet (US$200mm more than a year ago). The positivity pertaining to the issue, unlike in October 2011, appeared more definitive and potent this time (FDI in multi-brand retail comes into effect, Hindustan Times). As in late 2011, Pantaloon’s trading volumes and volatility levels spiked up again. However, this time, since the announcement, the stock rallied, not collapsed, by 20% (37% to peak post the news) with the benchmark Sensex up 10% during the same period. Investors felt much more confident this time and, had they bought the stock, would have successfully generated alpha.


Pantaloon Retail – Share Price Action + Trading Volumes 2012 (Source: Bloomberg):

The above example explicitly showcases the role of cognitive biases in tactical investing, as well as how collective “sentiment” and its relevant magnitude (i.e. the relative extent of positivity or negativity, measured through linguistic readers and similar software; Thomson Reuters and RavenPack term such metrics “sentiment scores” and “news scores” respectively) have the knack of incorporating more than mere fundamentals in influencing and/or guiding asset prices (in our case, Pantaloon’s equity value).

The necessity of constantly quantifying the extent and direction of such sentiment or momentum, and its consequent impact on return/alpha-generation, is thus set to become an important aspect of portfolio management and allocation. In fact, this subject becomes that much more important when viewed against the backdrop of an exponentially higher share of algorithmic trading and Direct Market Access (DMA) pipes across financial markets globally (the subject of the next edition of Short n’ Sharpe).

For now, it seems safe to assume that [systematic] News Analytics – one among multiple modes of investing – might matter more than one thinks it does. How large a component it really becomes within the realm of portfolio management, though, will only be apparent over time.
