Vaccine co-mentions in the news are surging again accounting for 15.33% of worldwide news about coronavirus, at the time of writing, and topping the league table of COVID-19 relevant topics on our news monitor.
The rise has come after the publication of promising results from early human trials of the leading frontrunner in the vaccine race AZN1222, which was developed by scientists at Oxford University in collaboration with pharmaceutical giant AstraZeneca.
Results published in the scientific journal the Lancet this week generated optimism after they showed the drug to be both safe and effective. The final 3rd stage of trials, involving a larger sample of 30,000 people, is underway and includes subjects in India, Brazil, and South Africa.
Yet, despite the breakthrough, questions still remain over whether the vaccine will provide enough immunity, whether it is long-lasting enough, and whether it will provide resistance to a broad enough cross-section of different people. It is also true that statistically, the odds are against it proving successful as only 1 out of every 10 vaccine programs crosses the finish line.
A report on how well broker recommendations performed during the COVID crisis shows signals based on RavenPack news sentiment data performed relatively well, coming 4th out of a list of 150, according to research firm Invisage Alpha.
The RavenPack signals generated a 16.84% return during the period between February 1 and June 15, which when considering the large sample - over 6800 signals in all - reflected a statistically robust outcome.

A key record high and low on the monitor is the spike in the Panic Index in Ukraine which has risen to an all-time high.
This bodes ill for the country since from past experience panic often ‘precedes pandemic’ with a sharp rise in the index often foreshadowing a similar increase in COVID cases.
Whilst this has not yet happened in Ukraine where daily cases have not risen to record highs so far, there is a risk the spread of the disease could worsen over the coming days.

High inflation has returned in developed markets after decades of lying low. In our latest paper, we show how to build an inflation-based asset allocation strategy using sentiment data and we illustrate that sentiment-based strategies outperform models that depend merely on past observed inflation values.
This year's RavenPack Research Symposium brought two intense days of knowledge sharing in London and New York, from 25 top experts in natural language processing, quantitative investing and machine learning. Together, we explored how firms can leverage new language models to generate alpha, better manage risk and respond to calls for more sustainable investment practices.
Human capital is at the heart of value creation. Our latest research demonstrates how unprecedented workforce insights, sourced from over 200 million job postings, can generate more alpha.
