Insights from the Geopolitical Sentiment Index made with Google Traits
Introduction
All through historical past, geopolitical stress and stress has been ever-present. From historic civilizations to as we speak’s world, world dynamics have been largely formed by wars, terrorism, and commerce disputes. Monetary markets, as all the time, have keenly noticed and been considerably influenced in consequence.
Our article delves into understanding this relation between geopolitical stress and monetary markets, significantly the fairness market. To briefly clarify our strategy, we search to quantify geopolitical stress via an observable Geopolitical Stress Index (GSI). Utilizing this index, we will discover the relation between geopolitical sentiment, good and unhealthy, and devices out there on monetary market. Lastly, we search to see if geopolitical sentiment is one thing that can be utilized to affect buying and selling selections and develop worthwhile buying and selling methods.
Literature Assessment
Our analysis is basically impressed by and a generalisation of comparable work carried out in a wide range of different papers out there at Quantpedia. Particularly, we check with an article titled “Can Google Traits Sentiment be Helpful as a Predictor for Cryptocurrency Returns?” through which we explored the affect 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 Greatest Geopolitical Occasions of the Previous Century investigates the affect the ‘worst one-day shocks and the largest geopolitical occasions of the previous century’ had on monetary markets. Whereas there’s overlap on this work with ours, we purpose to develop 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 targets. 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.
Outdoors of Quantpedia, a paper Geopolitical Risk, Market Capitalization, and Portfolio Return explores ideas just like ours, albeit specializing in simply the market; subsequently, the main focus of the research is totally different from that in our research. Notably, their use of regime switching fashions gives an extension that might improve our personal evaluation, offering insights into totally 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 offers free real-time knowledge and is straightforward 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 introduced as a proportion relative to the best focal point over time, now we have to rescale every month’s curiosity degree to the utmost noticed curiosity inside the knowledge as much as that date. This adjustment was executed 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, check with our earlier work on the Crypto Sentiment Index. Lastly, we averaged the normalized values throughout all key phrases to provide the ultimate GSI.
The key phrases used for Geopolitical Sentiment index embody Conflict, Battle, Army, Nuke, Weapons, Missile, Enemy, Risk, Bomb, Military, Terrorist, Terrorism, Warfare, Killed, Invasion. Information assortment started in January 2008 and extends via 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 guage the potential affect of the Geopolitical Sentiment Index (GSI) on monetary markets, we started by testing the speculation that adjustments within the GSI would have an effect on the unfold between a defense-focused ETF and a worldwide 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 big relationship. We consider the first cause for this outcome lies within the composition of most “protection” ETFs, which generally mix protection and aerospace firms. The inclusion of aerospace corporations, that are much less straight tied to protection budgets and geopolitical stress, probably diluted the affect of geopolitical occasions, making these ETFs much less delicate to adjustments within the GSI.
Given the inconclusive outcomes from the protection ETF evaluation, we explored different avenues to use the GSI. A very promising course emerged once we examined the connection between geopolitical stress and the danger premium related to small-cap shares. It’s well-documented in monetary literature that small-cap shares carry greater danger relative to their large-cap counterparts (Zakamulin, 2011; Hameed, Lof, Suominen, 2022). This greater danger usually interprets into underperformance following intervals of elevated uncertainty or danger, comparable to these indicated by rising geopolitical stress. Then again, large-cap shares, that are usually perceived as safer investments, are inclined to carry out higher throughout financial downturns or in environments characterised by geopolitical stress (Ali, 2024).
The differential affect 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 could immediate buyers to demand the next 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 higher monetary stability, could appeal to buyers searching for security, thus explaining their comparatively stronger efficiency in such intervals. This dynamic offers 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 targeted 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 steady large-cap shares. The reversal technique was employed as a result of fairness markets sometimes value in info, together with geopolitical dangers, virtually instantly. Consequently, predicting these dangers is difficult. Nonetheless, by observing the rapid market reactions, we will capitalize on the eventual return to a traditional 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 quick on IWM and lengthy on SPY, anticipating that any preliminary outperformance of small-cap shares would revert because the geopolitical stress dissipated. The portfolio was rebalanced month-to-month to mirror adjustments within the GSI.
We assessed the effectiveness of utilizing GSI proportion adjustments over totally different time horizons—1, 3, 6, 9, and 12 months—to seize totally different formation intervals of the index adjustments. Amongst these, the 12-month GSI proportion change had essentially the most important 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 adjustments. The outcomes recommend that longer-term adjustments 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 creating the Geopolitical Sentiment Index (GSI). Our major goal was to find out whether or not adjustments within the GSI may 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 world inventory ETFs. Nonetheless, our empirical evaluation didn’t reveal a big relationship, a outcome probably attributed to the composition of protection ETFs, which regularly embody each protection and aerospace firms, thereby diminishing their sensitivity to geopolitical occasions.
Recognizing the constraints of this strategy, we redirected our focus in the direction of a doubtlessly extra impactful software 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, focusing 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 best, reaching a Sharpe ratio of 0.38. This discovering underscores the potential utility of the GSI as a software 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 important findings, this research highlights the worth of exploring different approaches when investigating complicated relationships, comparable 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 world markets. Future analysis may improve this strategy by incorporating extra components or extra granular knowledge, thereby doubtlessly enhancing the predictive energy and applicability of the GSI.
