Insights from the Geopolitical Sentiment Index made with Google Traits
Introduction
All through historical past, geopolitical stress and rigidity has been ever-present. From historic civilizations to right this moment’s world, international dynamics have been largely formed by wars, terrorism, and commerce disputes. Monetary markets, as at all times, have keenly noticed and been considerably influenced consequently.
Our article delves into understanding this relation between geopolitical stress and monetary markets, significantly the fairness market. To briefly clarify our method, we search to quantify geopolitical stress by means of an observable Geopolitical Stress Index (GSI). Utilizing this index, we are able to discover the relation between geopolitical sentiment, good and unhealthy, and devices accessible on monetary market. Lastly, we search to see if geopolitical sentiment is one thing that can be utilized to impression buying and selling selections and develop worthwhile buying and selling methods.
Literature Evaluation
Our analysis is basically impressed by and a generalisation of comparable work carried out in a wide range of different papers accessible at Quantpedia. Particularly, we consult with an article titled “Can Google Traits Sentiment be Helpful as a Predictor for Cryptocurrency Returns?” by which we explored the impression of sentiment on the cryptocurrency market, a theme we additionally examine in our personal evaluation of the fairness market.
Moreover, an article The Worst One-Day Shocks and the Largest Geopolitical Occasions of the Previous Century investigates the impression the ‘worst one-day shocks and the most important geopolitical occasions of the previous century’ had on monetary markets. Whereas there’s overlap on this work with ours, we goal to increase on this work carried out on this analysis by understanding the relation between the inventory market and geopolitical sentiment holistically.
Moreover, one other work from Quantpedia Army Expenditures and Efficiency of the Inventory Markets carefully aligns with our analysis aims. This research examines the connection between army expenditures and fairness markets, touching upon facets of geopolitical sentiment. In distinction, our research goals to generalise this to geopolitical dangers past simply army spending.
Exterior of Quantpedia, a paper Geopolitical Risk, Market Capitalization, and Portfolio Return explores ideas much like ours, albeit specializing in simply the market; subsequently, the main target of the research is completely different from that in our research. Notably, their use of regime switching fashions affords an extension that would improve our personal evaluation, offering insights into completely different dynamics inside our analysis.
Methodology
We developed the GSI from Google Traits to measure public curiosity in geopolitical points as a result of it gives free real-time knowledge and is easy to construct. This enables us to gauge shifts in sentiment primarily based on how usually folks seek for phrases associated to geopolitical tensions. Since Google Traits knowledge is offered as a proportion relative to the best focal point over time, we now have to rescale every month’s curiosity stage to the utmost noticed curiosity inside the knowledge as much as that date. This adjustment was carried out iteratively, month by month, making certain that every month’s knowledge was normalized towards the height curiosity noticed to that time. For extra detailed methodology for rescaling, consult with our earlier work on the Crypto Sentiment Index. Lastly, we averaged the normalized values throughout all key phrases to supply the ultimate GSI.
The key phrases used for Geopolitical Sentiment index embrace Struggle, Battle, Army, Nuke, Weapons, Missile, Enemy, Risk, Bomb, Military, Terrorist, Terrorism, Warfare, Killed, Invasion. Information assortment started in January 2008 and extends by means of July 2023. For every key phrase, we recalculated Google Traits’ “relative measure of curiosity” on the finish of the pattern interval to the “relative measure of curiosity in every month” and averaged particular person sentiment numbers.

Outcomes
To judge the potential impression of the Geopolitical Sentiment Index (GSI) on monetary markets, we started by testing the speculation that modifications within the GSI would have an effect on the unfold between a defense-focused ETF and a world inventory ETF. This speculation was grounded within the assumption that elevated geopolitical stress would drive up protection spending, thereby benefiting firms inside the protection sector and widening the unfold between these ETFs. Nonetheless, our empirical evaluation didn’t verify a major relationship. We imagine the first cause for this consequence lies within the composition of most “protection” ETFs, which generally mix protection and aerospace firms. The inclusion of aerospace companies, that are much less straight tied to protection budgets and geopolitical stress, doubtless diluted the impression of geopolitical occasions, making these ETFs much less delicate to modifications within the GSI.
Given the inconclusive outcomes from the protection ETF evaluation, we explored different avenues to use the GSI. A very promising route emerged after we examined the connection between geopolitical stress and the chance premium related to small-cap shares. It’s well-documented in monetary literature that small-cap shares carry increased danger relative to their large-cap counterparts (Zakamulin, 2011; Hameed, Lof, Suominen, 2022). This increased danger usually interprets into underperformance following durations of elevated uncertainty or danger, equivalent to these indicated by rising geopolitical stress. Alternatively, large-cap shares, that are typically perceived as safer investments, are likely to carry out higher throughout financial downturns or in environments characterised by geopolitical rigidity (Ali, 2024).
The differential impression of geopolitical stress on small-cap versus large-cap shares suggests a nuanced mechanism at play. In periods of elevated geopolitical stress, the heightened uncertainty might immediate buyers to demand a better danger premium for holding small-cap shares, that are extra weak to financial disruptions. Conversely, large-cap shares, with their extra established market positions and better monetary stability, might entice buyers in search of security, thus explaining their comparatively stronger efficiency in such durations. This dynamic gives a compelling clarification for the various efficiency patterns of small-cap and large-cap shares in response to fluctuations in geopolitical sentiment, as captured by the GSI.
To evaluate the predictive energy of the GSI on monetary markets, we carried out a reversal buying and selling technique centered on the unfold between two key ETFs: the iShares Russell 2000 ETF (IWM), which represents small-cap shares, and the SPDR S&P 500 ETF Belief (SPY), which tracks large-cap shares. The IWM-SPY unfold serves as a measure of relative efficiency between these two segments of the fairness market, with IWM representing riskier small-cap shares and SPY representing the extra secure large-cap shares. The reversal technique was employed as a result of fairness markets usually worth in info, together with geopolitical dangers, nearly instantly. Consequently, predicting these dangers is difficult. Nonetheless, by observing the rapid market reactions, we are able to capitalize on the eventual return to a standard state, thus exploiting the reversal within the IWM-SPY unfold.
Our technique was primarily based on the proportion change within the GSI on a month-to-month foundation. Particularly, when the GSI was rising, as a substitute of anticipating large-cap shares to proceed outperforming small-caps, the technique concerned taking a brief place in SPY and a protracted place in IWM, anticipating that the preliminary market response would reverse because the scenario stabilized. Conversely, when the GSI was declining, the technique concerned going brief on IWM and lengthy on SPY, anticipating that any preliminary outperformance of small-cap shares would revert because the geopolitical rigidity dissipated. The portfolio was rebalanced month-to-month to replicate modifications within the GSI.
We assessed the effectiveness of utilizing GSI proportion modifications over completely different time horizons—1, 3, 6, 9, and 12 months—to seize completely different formation durations of the index modifications. Amongst these, the 12-month GSI proportion change had probably the most vital outcomes, reaching a risk-adjusted return, as measured by the Sharpe ratio, of 0.38. Desk 1 presents the efficiency metrics of the technique throughout the chosen time horizons of GSI modifications. The outcomes counsel that longer-term modifications in geopolitical sentiment extra successfully explains the relative efficiency of small-cap versus large-cap shares.

Conclusion
On this research, we got down to discover the connection between geopolitical sentiment and monetary markets by growing the Geopolitical Sentiment Index (GSI). Our major goal was to find out whether or not modifications within the GSI might function a dependable predictor for asset returns inside the fairness market. Initially, we hypothesized that geopolitical stress would straight affect the unfold between defense-related ETFs and international inventory ETFs. Nonetheless, our empirical evaluation didn’t reveal a major relationship, a consequence doubtless attributed to the composition of protection ETFs, which regularly embrace each protection and aerospace firms, thereby diminishing their sensitivity to geopolitical occasions.
Recognizing the constraints of this method, we redirected our focus in direction of a doubtlessly extra impactful utility of the GSI—the affect of geopolitical danger on the efficiency differential between small-cap and large-cap shares. This dynamic drives the relative efficiency of small-cap shares in comparison with their large-cap counterparts, aligning with established monetary theories.
To validate this perception, we carried out a reversal buying and selling technique primarily based on the GSI’s month-to-month proportion change, concentrating on the unfold between the IWM, representing small-cap shares, and the SPY, representing large-cap shares. The evaluation demonstrated that the 12-month GSI proportion change was the simplest, reaching a Sharpe ratio of 0.38. This discovering underscores the potential utility of the GSI as a instrument for informing funding selections, significantly in understanding the relative efficiency dynamics between small-cap and large-cap equities.
In conclusion, whereas our preliminary speculation relating to the protection ETF unfold didn’t yield vital findings, this research highlights the worth of exploring different approaches when investigating advanced relationships, equivalent to these between geopolitical sentiment and market conduct. The Geopolitical Sentiment Index has proven promise used with the relative efficiency between small-cap and large-cap shares, providing buyers a nuanced perspective for navigating the uncertainties inherent in international markets. Future analysis might improve this method by incorporating further components or extra granular knowledge, thereby doubtlessly bettering the predictive energy and applicability of the GSI.
