Political Stability Drives Sustainable Re-rating of Japanese Equities

This conversation with Bruce Kirk, Goldman Sachs' Chief Japan Equity Strategist, reveals that the recent snap election victory for Prime Minister Abe is far more than a political win; it's a catalyst for a potential sustainable re-rating of Japanese equities, driven by increased political stability and shifting global investor perceptions. The hidden consequence is that the market's upward trajectory, historically observed after similar LDP supermajorities, is not solely dependent on new policies but on the duration of stable leadership and the resulting reduction in risk premiums. This offers a significant advantage to investors who understand that the current rally might be underpinned by a longer-term shift in foreign positioning, not just short-term policy expectations. Those who recognize this dynamic can capitalize on delayed payoffs and avoid the common pitfall of mistaking temporary sentiment for enduring change.

The Long Game: How Political Stability Unlocks Market Multiples

The recent snap election in Japan, resulting in Prime Minister Abe's significant victory, has been painted as a straightforward win for pro-growth policies. However, Bruce Kirk of Goldman Sachs Research argues that the market's reaction, and indeed its future trajectory, is deeply rooted in a more systemic understanding of political stability and its impact on investor psychology. While immediate policy shifts are important, the truly consequential aspect lies in the duration of leadership and the resulting reduction in perceived risk. Historically, Japanese equities have seen a notable expansion in multiples following elections where the LDP-led coalition secured a two-thirds supermajority. This isn't just about the policies themselves, but about the market's confidence that those policies will be implemented consistently over a longer period.

Kirk points to past instances -- 2005, 2012, and 2014 -- where such victories led to an average 20% market jump in the first three months. More critically, over the subsequent nine months, the TOPIX multiple expanded by approximately two to three points. This expansion is directly linked to the expectation of longer prime ministerial tenures, which, since World War II, have averaged a mere year and a half. Extended stability lowers the market's risk premium, making it a more attractive destination for foreign investors. This influx of capital, in turn, further drives up valuations. The implication here is that the current rally isn't just about the announcement of pro-growth policies, but about the endurance of the administration implementing them.

"The average tenure of a Japanese prime minister since World War II is about a year and a half. So that would suggest more political stability, more policy continuity, and that should in turn lower the risk premium of the market itself."

This focus on duration highlights a key failure of conventional wisdom, which often fixates on immediate policy announcements. The market's sustained upward movement, however, is often a function of delayed payoffs that conventional short-term analysis misses. For investors, this translates into a competitive advantage: understanding that the true value unlock comes not from the election itself, but from the period of stability it ushers in. This stability allows for a more predictable environment for corporate governance reforms and structural changes, which are crucial for a sustainable re-rating of the market.

The Unseen Hand of Foreign Flows: Beyond the Initial Surge

While the election victory provides a strong political backdrop, the sustained re-rating of Japanese equities hinges significantly on foreign investor positioning. Kirk notes that foreign investors began repositioning into Japanese equities around the market bottom in late 2022, a typical pattern at the start of a market cycle. However, a significant correction in the summer of 2024, triggered by a Bank of Japan sell-off, caused foreign investors to divest approximately 13 trillion yen in cash and futures. This event serves as a stark reminder of how quickly sentiment can shift and how deeply foreign flows influence market dynamics.

The current positioning, while improving, is still not at "stretched" levels when viewed from a longer-term perspective, particularly compared to the start of "Abenomics" in late 2012. Recent data shows substantial net buying by foreigners in the week prior to the election, reaching near-record levels and significantly contributing to the year-to-date buying. This pattern, where Japan is outperforming the US in dollar terms, tends to attract further foreign capital, creating a virtuous cycle that pushes multiples higher. This dynamic underscores the systemic feedback loop: strong performance attracts foreign investment, which in turn fuels further performance.

"When that happens, it tends to push the market higher and push the multiples higher, which is the assumption we're making in our target price. So if you think about the geographic diversification trade out of the US that Peter Oppenheimer has been focused on for a while now, it feels like that is playing out in Japan at the moment."

The "geographic diversification trade out of the US" is a critical insight here. It suggests that the current strength in Japan is not an isolated phenomenon but part of a broader global rebalancing. Investors are actively seeking alternatives to an increasingly concentrated US market. This trend, coupled with the political stability in Japan, creates a compelling case for sustained foreign inflows. The advantage for investors lies in recognizing this macro trend and understanding that Japan is a beneficiary of a global search for yield and diversification, a dynamic that can sustain market gains long after the initial election euphoria fades.

Navigating the Currents: Risks and the True Test of Durability

Despite the positive outlook, the path forward for Japanese equities is not without its risks. Kirk identifies several key areas that warrant attention, chief among them being the potential for a prime minister's unexpected resignation. Historically, such events have marked the peak of market rallies, as seen in 2005 when Prime Minister Koizumi's sudden departure coincided with the market's peak. While the current prime minister's victory appears to offer a degree of security, any health issue or unforeseen political scandal could disrupt the stability narrative.

Policy risk also remains a significant concern. Any action by the administration that unsettles the bond or FX markets could spill over into broader risk sentiment, impacting equities. The proposed consumption tax cut, for instance, remains a point of focus, with the inherent difficulty of reversing such a measure later posing a fiscal sustainability question. Beyond domestic factors, the ever-present external risks of a US economic downturn, geopolitical events, or a global growth shock cannot be ignored, although these are not currently part of the base case outlook.

Perhaps the most subtle yet critical risk Kirk highlights is the market's unusual period of steady growth without significant corrections. The fact that the market has risen steadily for nearly a year without a sell-off greater than 5% is, paradoxically, concerning. Such prolonged periods of calm can breed complacency and mask underlying vulnerabilities. The historical pattern of Japanese equity market corrections occurring roughly three times a year suggests that a period of increased volatility is statistically probable.

"The last one we had was immediately after Liberation Day last April, so almost a year ago. So since Liberation Day, the market has just really grown steadily higher since then, and in almost a year, we haven't seen any sell-off drastic enough to push foreigners out of the market again. So that's a very unusual situation which in turn sort of makes it quite concerning."

-- Bruce Kirk

This observation points to the ultimate test of durability for the current rally. True competitive advantage comes not from anticipating the next upswing but from understanding the system's resilience and potential failure points. The market's current upward momentum, while positive, may be building a foundation that is more susceptible to shocks than it appears. Investors who prepare for inevitable corrections, rather than assuming a perpetual upward climb, will be better positioned to navigate the inherent volatility and capitalize on opportunities that arise during downturns. The real win isn't just participating in the rally, but enduring it and emerging stronger.

Key Action Items

• Immediate Action (Next Quarter):
  • Analyze historical patterns of TOPIX multiple expansion following LDP supermajorities to understand the typical duration and magnitude of gains.
  • Monitor foreign investor positioning data closely, particularly net buying trends, to gauge sustained interest beyond short-term sentiment.
  • Assess the explicit policy agenda of Prime Minister Abe's administration, focusing on structural reforms and corporate governance, not just headline fiscal announcements.
• Medium-Term Investment (6-12 Months):
  • Evaluate companies demonstrating aggressive shareholder return policies and investment in growth, as these are key drivers of sustainable ROE improvement.
  • Consider the impact of potential sector consolidation through M&A, identifying companies well-positioned to benefit from restructuring.
  • Develop a strategy for managing portfolio volatility, anticipating potential corrections and identifying undervalued assets that may emerge.
• Longer-Term Investment (12-18 Months+):
  • Identify companies whose business models are resilient to external shocks (e.g., global growth slowdowns, geopolitical events).
  • Re-evaluate foreign investor allocation to Japan relative to historical averages and other global markets to identify potential shifts.
  • Build a diversified portfolio that can withstand potential policy missteps or unexpected leadership changes, focusing on fundamental strength over speculative momentum.
