[Fundamental viewpoint]
Last week, U.S. stock markets saw a weekly rise in stock indices, driven by a rebound in some AI and semiconductor-related stocks and a continued stream of strong quarterly earnings reports.
Weekly percentage change: NY Dow : +1.04%, NASDAQ: +1.59%, S&P 500: +1.05%
On the other hand, medium- to long-term
risks include concerns over military conflicts in the Middle East and the
protracted conflict in Ukraine; financial instability caused by inflation and
rising interest rates driven by high crude oil prices, along with concerns
about a global economic slowdown; and concerns over a real estate bubble burst
and an economic slowdown in China. Furthermore, these factors have raised
concerns about the onset of stagflation. In addition, continued vigilance is
required regarding geopolitical risks in Latin America and East Asia..
Considering the OECD’s nominal GDP forecasts for 2026, the Japanese market is overvalued by 0.15 points relative to the U.S. market. This overvaluation stems from the difference between the S&P 500’s P/E ratio of 21.0 and the projected P/E ratio of 18.1 for the constituent stocks of the Nikkei 225 for the current fiscal year, as well as the interest rate differential and the difference in GDP growth rates between Japan and the U.S.
For the Japanese and U.S. markets to reach equilibrium, the following conditions must be met:
Compared to the current Nikkei 225 price, the difference in GDP growth rates between Japan and the U.S. for 2026 must narrow by an additional 0.15 percentage points relative to the OECD forecast (either Japan’s forecast must be revised downward or the U.S.’s must be revised upward). Alternatively, the projected P/E ratio for the current fiscal year for Nikkei 225 constituent stocks must reach approximately 17.5. Or, the Nikkei 225 must reach approximately 62,710 yen.
Consequently, the Japanese market is overvalued by about 1,660 yen in the medium to long term.
From a fundamental perspective, the Japanese market could be considered more attractive than the U.S. market. Last week, the Japanese market’s overvaluation widened..
[Conditions for Nikkei average rise]
In the future, the following assumptions are necessary for the Nikkei average to rise further.
① Rising US market
② Increase in profit forecast for the current fiscal year above the previous year's level
③ Further depreciation of the yen due to the widening interest rate gap between Japan and the U.S.
④ Upward revision of Japan's 2026 GDP estimate (now +2.9%) by OECD
⑤ Foreign investors over-buying
Looking at recent movements
① The weekly leg of the NYDow was positive last week. The daily is above the 200-day line and the clouds on the Ichimoku Chart. The weekly leg of the NASDAQ was positive. The daily is a above the 200-day line and within the clouds on the Ichimoku Chart. This week, the focus will be on whether the NYDow can keep above the 25-day line.
② Following the release of earnings results, the projected ROE for Nikkei 225 constituent stocks stood at +10.7%. This represents an improvement of +1.7 percentage points compared to three months ago. The profit growth rate was +13.7%, marking an improvement of +16.1 percentage points compared to three months ago.
③ Long-term U.S. interest rates rose, widening the interest rate differential between Japan and the U.S. from 1.90 to 1.96. The dollar-yen exchange rate moved from the 163-yen range to the 157-yen range, reflecting a strengthening of the yen. The Dollar Index fell 1.64% for the week.
④ The OECD's nominal GDP growth rate for Japan and the U.S. in 2026 is expected to be +2.9% for Japan and +5.8% for the U.S., so the Japanese market is 2.9 percentage points inferior in this aspect.
⑤ Net buying was recorded in the fourth week of July. It is highly likely that net selling occurred in the fifth week of July, and net selling is expected this week. Last week, out of the five points, point ① was a bullish factor.
[Technical viewpoint]
From a technical perspective, the Japanese market is overvalued by 7.5 percentage points (equivalent to approximately 4,830 yen for the Nikkei 225) relative to the NASDAQ based on the 200-day moving average deviation. Meanwhile, it is overvalued by 6.2 percentage points (equivalent to approximately 3,990 yen for the Nikkei 225) relative to the NY Dow based on the 200-day moving average deviation.
The Japanese market is performing better than the Dow Jones and NASDAQ. The VIX, an indicator of volatility in the U.S. market, fell to 16.0 for the week. The Nikkei VI fell to 29.4 for the week. While the U.S. market is in a “normal” state, the Japanese market is in a state of “fear.”
The Nikkei Average is above the 9-day and below 25-day moving averages. A “yellowd light” is lit for the short-term trend.
The Nikkei Average is within the cloud of the Ichimoku Kinko Hyo chart. The overall deviation rate is +8.5%, and the deviation rate from the 200-day moving average is +13.0%. With two factors positive, a “yellow light” is lit for the medium-term trend.
In the US market, the NY Dow is above the 9-day line and 25-day and 200-day lines. It is above the clouds of the Ichimoku chart.
The NASDAQ is above the 9-day line and below 25-day and above 200-day lines. It is within the clouds the Ichimoku Chart.
The U.S. market is showing a “yellow light” in the short term and a “yellow light” in the medium term.
[Outlook for this week]
In the U.S. market, concerns about an economic downturn driven by rising long-term interest rates—a result of the prolonged conflict in the Middle East—and high oil prices are likely to be the primary focus for the time being.
Looking at the technical aspects, the U.S. market is in a medium-term no trend and a short-term down trend. The Japanese market is in a medium-term no trend, and the short-term is down trend.
Analysis of the foreign exchange market indicates that the yen has shifted towards depreciation, with the low of 139 yen reached in April 2025 marking the bottom. This week, the yen is expected to trade between the 157 and 160 yen per dollar range.
This week, U.S. markets will likely continue to closely monitor developments in the Middle East. Volatility in AI-related stocks is expected to persist, with the situation evolving following earnings reports from SpaceX and AMD. On the economic front, key indicators such as the employment report, JOLTS, the ADP report, the ISM PMI, manufacturing orders, and the trade balance will be released. Globally, data including eurozone industrial production, Germany’s trade balance, China’s PMI and trade balance, and Japan’s wage data will be released.
Last week, the Nikkei Average traded above the expected range. The high was about 1,050 yen above the upper limit, and the low was about 530 yen above the lower limit.
This week, the Nikkei Average is expected to trade within a range defined by the 25-day moving average (currently around 66,880 yen) on the upside and the -2σ Bollinger Band
With uncertainty surrounding the situation in the Middle East persisting, this week is likely to be one in which the strength of the rebound in AI and semiconductor-related stocks will be put to the test.
