Equity market as a retail playground backed by politicians and smart money<\/strong><\/p>

Financial markets continue to evolve, with sentiment playing an increasingly important role. Given that investing is a money-making machine, everyone wants to participate. Since the COVID-19 pandemic, markets have been increasingly influenced by retail investors, whose investment decisions are often susceptible to sentiment, Reddit posts, FinTwit commentary on AI bottlenecks, and, more recently, the buying and selling activity of politicians. As a result, we have seen the emergence of even \u201cautopilots\u201d tracking politicians\u2019 trades, while the prices of certain stocks can jump after politicians disclose their transactions\u2014as happened with Mastercard and Visa after Donald Trump revealed significant purchases in these companies. <\/p>

It is understandable that, in an environment of complete uncertainty, everyone wants a guru to follow. But are these gurus right? Is there consistent evidence that following \u201csmart money\u201d or politicians\u2019 trades can actually make you a successful investor? <\/p>

In this article, we dive into the topic, looking at which external signals are worth following and which are more akin to PR and hype, signals that may quickly disappear, leaving a weak company in the portfolio after it was bought on a hyped-up buy signal from a politician or large investor. We focus on three relevant pillars: insider trades, large institutional investors, and politicians. The matter is complex, which may translate into ambiguous conclusions, but with a smart approach, these signals can provide excellent confirmation of a thesis based on fundamentals and valuation. <\/p>

Insider trades<\/strong><\/p>

Insider trade is perhaps the most relevant signal with regard to future fundamental performance and much more reliable than blindly following \u201csmart money.\u201d Information asymmetry in financial markets is obvious, so investors naturally tend to track insider transactions. There are a number of studies indicating that insider selling does not necessarily signal a deterioration in future performance, as insiders sometimes need to cash out or exercise their options. However, when an insider sells a large proportion of their existing position, it is usually a negative signal1. Interestingly, smaller sales have been correlated with significantly positive subsequent returns. <\/p>

Surely, stock purchases by senior executives are relatively rare, but they are usually a positive signal with relatively strong predictive power, as illustrated in Figure 1. A Norwegian study found that executives below the top management level earn abnormal returns on purchases of their own-company stock: +84 bps after one month and +426 bps after six months2. Nevertheless, investors should still be careful and conduct their own research, as CEOs can also be wrong or may simply be demonstrating their confidence and loyalty to the company. For instance, Netflix\u2019s CEO bought shares after subscriber growth disappointed in January 2022, but the stock continued to come under pressure. Similarly, Nike directors, including the famous Apple executive Tim Cook, and Nike\u2019s CEO bought shares towards the end of 2025, yet the company continued to struggle amid serious structural challenges. <\/p>

Large institutional investors<\/strong><\/p>

Not all institutional investors can be classified as \u201csmart money,\u201d so there is limited value in blindly following their trades, as the predictive power for abnormal returns is generally limited. According to recent academic research, however, several types of institutional activity do have meaningful predictive power for future abnormal returns. <\/p>

Kirk indicates that institutional ownership exceeding the expected level based on predefined company characteristics can be a predictor of strong fundamentals and price momentum3. Koch finds evidence that, in general, mutual funds are not worth following blindly. Instead, attention should be devoted to \u201cleader\u201d funds\u2014the first investors to trade, whose actions are subsequently followed by the rest of the mutual-fund cohort4. <\/p>

Another study finds that extreme increases or decreases in institutional ownership predict subsequent abnormal returns around earnings announcements5. The effect is particularly strong when the change is driven by a relatively small number of institutions making disproportionately large trades. A perfect example was recently identified when screening 13-F filings for 2Q\u201926 new entries and exits: Veeva, a US software company serving the healthcare industry, where we had also initiated a position earlier. Veeva ranked No. 6 on the list of new institutional buys. The company subsequently reported excellent 2Q results, sending its share price up by 15%. Institutional money can therefore be informative, but \u201cinstitutions are buying\u201d is too broad a signal. Academic evidence suggests that the strongest predictive power comes from abnormal accumulation by a relatively small number of sophisticated investors, particularly when a skilled institution establishes a new, meaningful position or materially increases an existing one. <\/p>

Politicians as traders<\/strong><\/p>

Following politicians\u2019 stock-market trades as an investment signal became particularly popular after the widely publicised case of Nancy Pelosi buying Nvidia ahead of favourable developments around the CHIPS Act. However, the picture is not that simple, and overall, the predictive power of political trades appears to be much lower than that of insider and sophisticated institutional trades. The \u201cFollow the Congress\u201d rhetoric is unlikely to generate superior returns, as congressional trading appears to resemble uninformed retail trading rather than informed trading6. However, there is certain evidence that politicians sitting on relevant committees overseeing particular legal matters or responsible for industry-specific legislation can earn higher returns. A well-known example is Kelly Loeffler, who sold travel-related stocks and bought Citrix, extreme beneficiary during work form home era, following a private briefing on the development of COVID-19. <\/p>

Implications for long-term investor<\/strong><\/p>

Summarising the trading signals provided by influential stakeholders\u2014insiders, institutional investors, and politicians\u2014based on the academic research, it can be argued that a number of signals have relatively strong predictive power, with insider transactions generally providing more reliable signals than institutional and political trades.<\/p>

Surely, a positive trading signal in itself does not create an investment thesis for a long-term position. There are cases where even CEOs have been mistaken. However, such signals can provide valuable confirmation of an investment thesis based on fundamentals and valuation. A negative signal, on the other hand, should certainly trigger the siren and red lights and prompt investors to investigate whether some negative development has been overlooked. The objective is not to blindly follow the \u201csmart money,\u201d but to use these signals as an additional source of information when testing an investment thesis. <\/p>
