The Nikkei 225 closed at 62,188.63 on 4 November 2026, down 893.23 points, or 1.42%, according to Nikkei Indexes. It had traded as low as 60,030.10 in the afternoon. The index finished well above that low and still ended below its previous close. Those two statements describe different comparisons within the same session.
The publisher's daily summary adds two pieces of context. Of the 225 constituents, 150 declined, 73 advanced and two were unchanged. Technology made the largest negative sector contribution in the published breakdown. These details help answer two different questions: how widely prices moved in one direction, and how much particular parts of the index contributed to the closing change.
Start with the comparison behind the headline
A daily close and a daily change are usually displayed together. The close is the value at the end of the session. The daily change compares it with the previous closing value. For this session, adding the reported 893.23-point decline back to 62,188.63 gives a previous closing reference of 63,081.86. That is the denominator for interpreting the approximately 1.42% fall. It is not the opening value for 4 November.
The Nikkei daily summary, whose displayed session heading was 4 November when consulted, lists an open of 62,973.16. That was 108.70 points below the previous close implied by the daily change. The session then closed 784.53 points below its opening value. Adding those two moves gives the reported 893.23-point decline. A reader using the opening value as the reference would therefore calculate a different percentage from the one in the headline.
The units matter as much as the comparison. An index point describes a move in the index level. A percentage expresses the same move relative to a reference. An 893.23-point move would be a different percentage if the index began at a substantially different level. This is why the points figure is useful for checking arithmetic, while the percentage can be easier to compare with another session.
Separate the range from the closing move
Nikkei's summary gives a high of 63,105.47 at 09:04 and a low of 60,030.10 at 13:37. Subtracting the low from the high gives a range of 3,075.37 points. The range measures the distance between the day's extremes. It does not measure what the index lost between one close and the next. On this day the high came early and the low came later, but the closing value was a separate observation again.
The close was 2,158.53 points above the reported low. That is an arithmetic description of where the session ended compared with its lowest point. It does not establish that the market rose continuously after 13:37 or explain why it finished where it did. The four values in a daily summary are enough to make a useful map of the session, but they are not a minute-by-minute record.
The high was slightly above the previous closing reference. The final close was below it. So a report based on the early high and another based on the close could describe different conditions without either being a transcription error. Before comparing two headlines, look for the time and the word close. If one figure is live and the other is final, the time difference can account for much of the discrepancy.
Why a morning snapshot can look worse than the close
Nikkei's index profile can display an intraday reading alongside a general explanation of the index. The captured profile showed 61,108.04 at 11:11 on 4 November. The index publisher's current values page later identified 62,188.63 as the close. The former is a timed observation from earlier in the session. The latter is the final reading used for the daily change.
When using a screen capture, preserve the time label as well as the value. A number copied out of a chart without its timestamp can look like a competing close. A screenshot that includes both the date and time allows the next reader to see what it establishes. The same practice helps with search snippets, which may have been collected earlier than the page you open.
The difference between two intraday snapshots is also distinct from the daily move. Suppose one person compared the 11:11 reading with the close and another compared the close with the prior close. The first person would see a gain between those two observations. The second would see a daily loss. The disagreement would vanish once each person wrote down the starting and ending values used in the calculation.
Read market breadth as a count
The daily summary records 150 declining constituents, 73 rising and two unchanged. Those counts sum to 225. About two thirds of the constituents declined. This is often called breadth, because it shows how widely a direction was shared. It gives each constituent one place in the tally. A small decline and a large decline both count as one declining issue.
Breadth answers a question that the closing level alone cannot. A fall in an index could coincide with declines in many members, or be concentrated in fewer influential names. The count for 4 November shows declines were more common among these 225 stocks. It does not tell you the size of each move, and the index's 1.42% decline is not a claim that every constituent fell by that amount.
A simple example makes the distinction useful. Imagine a five-member index in which three members fall slightly and two rise sharply. The count would show more decliners even though the two increases might offset the three losses in the calculated index. Reverse the sizes of those moves and the same breadth count could accompany a decline. To understand the actual Nikkei session, read breadth beside the closing figure rather than using either one as a substitute for the other.
Understand what price weighting changes
Nikkei's official index profile describes the Nikkei 225 as a price-weighted index of 225 stocks selected from the Tokyo Stock Exchange's Prime Market. This differs from assigning each company equal weight. It also differs from ranking companies by market capitalisation. The provider's published constituent weights offer a way to see how much influence individual names have in the index at a given point.
A large weight and a large daily contribution are different ideas. Weight describes influence before considering the size and direction of a day's move. Contribution describes how much the move adds to or subtracts from the index calculation over the period being measured. A heavily weighted component can have little effect on a day when its price barely changes. A less heavily weighted component can still matter when it moves sharply.
This also explains why a list of the largest companies is insufficient for reconstructing the Nikkei's change. Start with the index provider's definition and use its own weights or contribution table for this benchmark. If you are comparing it with another index, look up the other provider's methodology separately. Shared membership between two indexes does not make their daily readings interchangeable.
Sector contributions explain the calculation, not the motive
Nikkei's published breakdown shows technology making the largest negative contribution on 4 November. Information and communications and materials also contributed negatively. Consumer goods contributed positively in the same table. That combination gives a more specific description than saying that all areas moved down together. Contributions describe how each sector affected the index calculation, not what every company in the sector did.
The sector weights table serves another purpose. It shows the proportions represented in the index at the reported snapshot. A sector's position in that table is not a ranking of the day's gains or losses. Use the contribution table for the direction and effect of the day's move. Use weights to understand why a sector can matter more to the benchmark than a count of its companies might suggest.
The figures establish what the provider recorded. They do not identify a single cause for the session. A news event might coincide with a move, but proving a causal account would require evidence beyond the index summary. For a factual recap, the strongest statements are the measured changes, the time labels and the published contribution breakdown. The distinction is particularly useful when the same day's news includes several plausible explanations and the first headline you see privileges one of them.
Compare the same kind of index on both sides
The provider's current values page lists the Nikkei Stock Average alongside several related indexes, including a total return index and inverse versions. Use the name printed on the row before copying the value. The main 62,188.63 closing figure refers to the Nikkei Stock Average, commonly called the Nikkei 225. A figure from one of the neighbouring rows may describe a different series even if its name also contains Nikkei 225.
A reader comparing two dates can make a small table with the index name, the session date, the closing level and the change from the previous close. Add another column for any time-specific observation. This keeps a midday reading from slipping into a list of final closes. It also prevents mixing a percentage calculated on a different index with the points move from the main benchmark.
On a rolling values page, the next session may replace the current headline. Preserve the date displayed with the row and use a dated summary where available. If the address and displayed heading differ, check the numbers against another official page before treating the record as evidence. For this session the main close and daily change agree between the daily summary as displayed and the provider's current values page.
Reconcile the sector figures with the headline
The summary reports about minus 755 points from technology and about minus 123 from information and communications. Together those two contributions account for roughly 878 points of downward pressure in the index calculation. Materials added a further negative contribution, while consumer goods offset part of the decline. The complete table contains seven sector rows. Reading just the two largest negative numbers gives useful context, but adding the positive rows is necessary when explaining why the final decline was smaller than the sum of all the negative contributions.
These entries are contributions to the index level. They are not percentage returns for portfolios invested in those sectors. A reader can check the overall direction by adding the signed contributions. A minus sign indicates a subtraction from the daily index move, and a plus sign indicates an offset or addition. If the resulting sum differs slightly from the headline, check whether the table rounds the inputs before assuming an omitted sector.
The provider also publishes a Japanese-language index profile. The English and Japanese pages describe the same benchmark methodology. Their displayed market snapshots can have different timestamps. Use either for the definition, then check the dated closing row for the final value. That distinction matters when comparing a Japanese-language headline seen in the morning with an English-language recap written after the session. A different timestamp can explain the difference even where both pages use the same index name and calculation.
Conclusion
The Nikkei 225 fell 1.42% to 62,188.63 on 4 November. It finished 2,158.53 points above the intraday low but remained 893.23 points below the prior close. Declines outnumbered advances among its constituents, and technology made the largest negative contribution in Nikkei's sector breakdown. Read those figures as a closing comparison, an intraday range, a count of constituents and a weighted contribution. Each describes a different part of the session.
Japan's Google Trends capture for 4 November placed the Nikkei average search third by volume over the previous 24 hours, with 100K+ searches and a label showing it had lasted five hours. The higher weather query lacked a dated primary forecast covering the requested next day in the material retrieved. The other higher row overlapped published U.S. election coverage. The search figures establish the recorded interest, while the index publisher supplies the market figures.
