Olivetree Securities is a truly unique independent agency broker. Founded in London, we have an exclusively institutional client base, and focus on the execution of European and US equities transactions. The firm's core products are brokerage services based upon content generated from the OTAS Decision Support Platform and upon the analysis of Event Driven situations.

Established in 2009, Olivetree Securities was designed to complement the work our clients already do, while aiding them in remaining abreast of the evolution of regulation within the market. By maintaining an independent and therefore non-conflicted structure we are able to give differentiated, reliable and timely insights into stocks and events. 

We have offices in both the UK and the US. We specialise in Evidence Based Finance using advanced data and analytics capabilities, bringing out differentiation through our use of OTAS, OTAS TradeShaper, and our market leading Events team.


Olivetree provides a truly differentiated offering to our clients,
based on three core factors: OTAS, Execution, Events.



The only sell-side firm using OTAS, the market leading DSP.

Olivetree Securities is on the only sell-side firm with access to OTAS (Olivetree Trading Analysis System), a market leading, award winning, Decision Support Platform (DSP) used extensively by the buy-side. It allows our sales and trading team to master big data, both structured and unstructured, and filter out the noise the rest of the market cannot avoid.



Genuinely independent analysis of complex event-driven situations.

Olivetree provides genuinely independent analysis of complex event-driven situations. We house the market-leading events team that studies opportunities across a range of event-driven scenarios, and also brings in depth analysis of difficult to model situations for clients with or without an event-driven background.



The street’s most sophisticated execution venue.

OTAS TradeShaper provides us with real time trade analysis and management, allowing Olivetree to minimise impact costs and focus on the goals of Best Execution. We use best in class algorithms, have market leading access to private BCN and dark pools, and act as consultants to many clients in keeping abreast of the latest trading technology.


Olivetree stands for four key products:

OTAS Generated Content, Event Driven Research, Most Sophisticated Execution, and OPIUM.



Olivetree Securities is the only sell-side firm to use OTAS, the market leading Decision Support Platform. We use the insights OTAS brings to produce a range of content, all of which is unique, pertinent, and relevant.

We are more than aware of how much data our clients receive, and need to highlight moves and levels that are statistically significant, or have historically reliable backtesting. OTAS allows us to do this, by identifying divergent outliers within the market and individual client’s investment universes. It provides us with clean, normalised data that allows us to separate signal from the rest of the noise the market sees.

We are the people that will tell you when that CDS move is the greatest in five years. Or when the options market is suddenly pricing in much more risk for your stock relative to the rest of the sector. Or when the short base is rapidly growing. Or that directors have begun to buy stock and more importantly when any of the above actually matters.

Be it through our morning observations, in-depth stock reports, or sector and market analysis, Olivetree’s OTAS content is truly unique and differentiated in its nature.



Olivetree’s market leading Event analysis team produces in-depth research of difficult to model situations, enabling clients with or without an Event Driven background to comprehend complex events in their stocks.

Our team provides genuinely independent analysis of the unique dynamics brought about by Corporate Actions. We highlight opportunities across a range of event-driven scenarios, with particular focus on difficult to model situations for clients without an event-driven background.

Our expertise and experience means we have a deep understanding of both the fundamental modeling required in this arena, but also a much broader perspective. The team has equity volatility and credit market specialisms to provide clients with insight on less transparent markets. We have also fostered relationships with independent advisory teams, allowing us access and insight into a multitude of situations. The team also works with OTAS to develop innovative tools, bringing new insight into situations with our advanced analytics, such as the OTAS Basket.

All PMs have a need for event driven expertise as soon as catalysts are triggered within their portfolio, be it takeovers, mergers, restructurings or spin offs. Thanks to our unique and unparalleled insight, our team guides clients in navigating atypical situations in stocks they may have owned for two hours or for ten years.



We pride ourselves having the most sophisticated execution tool kit on the Street. We are not just an execution venue, we also act as a consultant to many clients regarding the rapidly changing trading environment. We have cutting edge technology in OTAS TradeShaper, along with market leading execution capabilities.

OTAS TradeShaper is a global real time trading analytics system that is changing the way both we and our clients trade. It provides real-time market microstructure analysis that arms our traders with the same information and insight as high frequency traders. It uses the same sophisticated mathematical models as leading HFTs to extract information from the market and identify significant conditions, and ensures our traders never miss a dislocation and have the information they need to figure out what is really going on and therefore make smarter trading decisions.

We can adapt our trading style by highlighting anomalies created by your interaction with all pools of liquidity, both low and high touch venues. We can determine optimal trading schedules based on predicted market conditions, and then dynamically update this as conditions change.

We take great care in maintaining confidentiality for our clients, ensuring anonymity in accessing liquidity sources, from exchanges to BCN’s to dark pools. We have universal access to best in class dollar and non-dollar algo providers and smart routing. We have access to 95% of all dark pools, provide ‘white label’ routing, and have connectivity to all major OMS and EMS.



OPIUM is the independent analysis of primary and secondary stock placings. Through our independent position, we offer clients guidance in navigating large liquidity events, using a variety of measures and expert knowledge to form our analysis.

We offer clients truly independent analysis of high volume events using historic modelling, impact analysis, and OTAS.

Our differentiated IPO analysis and intelligence provides clients with the guidance they need through these delicate events. Our secondary block placing model uses volume, volatility and OTAS analysis along with expert experience, to provide quick and succinct analysis on every impactful secondary placing in the market.
