Conclusion at the beginning: As of 10:15 AM on August 3, 2026

The Nikkei Stock Average (62,788.43 yen) is at a crossroads where short-term, medium-term, and long-term moving averages are signaling completely different trends during the correction phase from the all-time high of 72,366.34 yen reached on June 25. By organizing structural facts for each time horizon rather than being swayed by short-term volatility, it is possible to improve the quality of decision-making for the next action.

1. Short-term analysis (3-month chart): Dead cross and short-term downward trend pressure

Facts on figures and moving averages

Period: May to August

Current price: 62,788.43 yen

Year-to-date high: 72,366.34 yen (June 25)

Moving averages: The 5-day moving average (light blue) is forming a dead cross, falling below the 25-day moving average (red).

Analysis and verbalization of the structure

On the 3-month chart, the market has entered a clear correction trajectory, peaking at 72,366 yen in late June. Since mid-July, a dead cross has occurred where the light blue 5-day line clearly crossed below the red 25-day line, and both lines have maintained a downward slope since. The current price of 62,788 yen is trading below both the 5-day and 25-day lines, indicating that selling pressure on rallies is dominant in the short term. This is a phase that requires risk management until the slope of the short-term moving averages turns from flat to upward, rather than emotional contrarian trading.

2. Medium-term analysis (6-month chart): Battle with the 75-day moving average and key levels

Facts on figures and moving averages

Period: March to August

Current price: 62,788.43 yen

Low: 51,063.72 yen (March 31)

High: 72,366.34 yen (June 25)

Moving Averages: 25-day moving average (light blue) and 75-day moving average (red).

Verbalizing Analysis and Structure

The 6-month chart depicts a correction phase following a significant rise of approximately 21,000 yen, from 51,063 yen at the end of March to 72,366 yen in late June. The current stock price of 62,788 yen has been pushed down to a level below the 75-day moving average (red: approximately 64,000 to 65,000 yen level), which is considered a medium-term support line. The gap between the 25-day and 75-day lines is narrowing, placing the market in an energy accumulation zone where the medium-term trend will be determined. This demonstrates the fact that both time-based and price-based adjustments are occurring simultaneously relative to the past rise.

3. Long-term Analysis (1-year chart): The major structural uptrend supported by the 26-week moving average

Facts on Numerical Values and Moving Averages

Period: July 2025 to August 2026

Current Price: 62,788.43 yen

Long-term Starting Point: 40,000 yen range (July–August 2025)

Highest Price: 72,366.34 yen (June 25, 2026)

Moving Averages: 13-week moving average (light blue) and 26-week moving average (red).

Verbalizing Analysis and Structure

From the long-term perspective of the 1-year chart, facts emerge that contrast with the short- and medium-term corrections. The ultra-long-term upward structure that began from the 40,000 yen range in the summer of 2025 remains fully intact. Although the 13-week line (light blue) shows a flat trend due to the decline from the high-price range, the 26-week moving average (red: approximately 60,500 yen level), which forms the backbone of the long-term trend, continues to show a strong upward slope. The current price of 62,788 yen is comfortably above this 26-week line, clearly indicating that long-term capital inflows and the real-demand-based growth trajectory have not collapsed.

4. 'Comprehensive Summary' and 'Decision-Making Agility'

The current position of the Nikkei Stock Average is a 'structural adjustment zone' caught between downward pressure from a short-term dead cross and support from the 26-week line, which continues a gentle long-term rise.

Rather than obsessing over creating a perfect plan to move only after confirming a complete bottom, the essential skill required of modern business professionals and investors is agility—calmly organizing facts according to time horizons and flexibly adjusting investment allocations and risk management in response to market changes.
