Nikkei 225: Smoke and Mirrors?
By Big Data Federation, Inc.

The Japanese equity market has been delivering astonishing performance lately and after 26 years of stagnation, Nikkei 225 has finally broken through its 1989 peak. Nikkei 225’s outperformance seems very aggressive and above all 33 major global equity indexes this year. Our in-depth analysis indicates this apparent outperformance is incorrectly observed and unfounded. In a groundbreaking study leveraging cutting-edge technology trained for global financial analysis, we have conducted a thorough analysis of the Japanese equity market like never before. Here we go.
Price Action
As of April 25, 2024, the Nikkei 225 index has returned 13.0% while the S&P 500 index has returned 6.40%. The equity indices are formed by simple equations combining a select set of stock prices and possibly their corresponding share counts (in the case of cap-weighted indices such as the S&P 500) and then stabilized by divisors. The key point here is that the local currency has a significant influence on the value of any equity index. Now that we have stated the obvious, let’s see how Nikkei 225 performed excluding the currency impact. For a US investor, Nikkei 225 has only moved up 4.74% in US Dollars year to date. For a Japanese investor, the S&P 500 moved up 16.23% in Japanese Yen in the same period. In other words, the S&P 500 has outperformed the Nikkei 225 in whichever side of the ocean the investor lived. So yes, the price action is smoke and mirrors.
Fundamentals
Utilizing mass data aggregation of point-in-time information and natural language processing to understand geographic sales exposure, we have delved deep into the fundamentals of Nikkei 225 companies.
Our analysis focuses on several key financial metrics for companies listed in Nikkei 225, including sales, gross margin, EBITDA (earnings before interest, taxes, depreciation, and amortization), and EBITDA margin. Fundamental aggregations are based on real-time earnings dates, capturing the financial dynamics as they unfold, and focused only on companies with consistent reporting data. We conduct our evaluation in US Dollars to eliminate the effects of local currency fluctuations, employing a methodical approach that averages local currency over the fiscal quarter start and end dates for accurate US Dollar comparison.
As shown below, the aggregated sales of Nikkei 225 companies in aggregation have demonstrated no growth, despite a consistent upward trend in prices. Even when using EBITDA — a measure intended to circumvent issues with bottom-line profitability and generally favors companies’ management — the trend stays the same. Notably, our approach does not account for survivorship bias, which should cast a more favorable light on Nikkei 225 fundamentals. However, despite this optimistic depiction, the underlying fundamental growth is markedly absent.

As illustrated below, the aggregate Nikkei 225 shows margins have also stagnated with no expansion whatsoever for the past 14 years. The Nikkei 225 aggregated gross and EBITDA margins are currently at 23% and 12%, respectively. S&P 500 is demonstrating much higher margins of 35% and 20% for gross income and EBITDA, respectively.

Our machines also automatically extracted geographical sales exposure for each company in the index from annual filings normalized proportionally to actual sales. Geographic sales distribution for Nikkei 225 companies, as demonstrated in the chart below, indicates that two-thirds of sales originations are from within Japan, mirroring the domestic sales focus observed in the S&P 500. In other words, the performance of Nikkei 225 companies is closely tied to their local economic conditions, much like those of the S&P 500.

Valuations
Valuation is complex and special care should be given to the methodology used. Mistakenly, market participants average valuation metrics of components of an index. Instead, we aggregate to avoid the skew of the averaging methods, which ignores the size of underlying fundamentals. The figure below illustrates our aggregated valuation for price to sales and price to EBITDA.

Since Nikkei 225's fundamentals have stagnated, the valuation of the index is completely determined by the price movement i.e. sentiment. Compared to the S&P 500, the Nikkei 225 valuation looks 50% cheaper due to the obvious lack of fundamentals growth.
Conclusion
In short, the statement that “Nikkei 225 has outperformed the S&P 500” is simply uneducated and not true. Nikkei 225 stocks remain cheap due to a good reason, no fundamentals growth. The higher valuation for Nikkei 225 should be backed by fundamental growth, otherwise, it will enter a risky proposition far more severe than the S&P 500 in the next global market meltdown.
