Is a PBR of 1.5 high or low: on three yardsticks, major stocks got split answers in 1,178 of 1,711 cases

KakaoBank's PBR (price to book ratio) is 1.50. U.S. Bancorp's PBR is 1.54. Even to two decimal places, they are almost the same number.

Yet as of September 21, 2026, the sector yardsticks for the two stocks pointed to opposite bands. KakaoBank's 1.50 sat at the 84.1% position among 44 Korean financial stocks, in the larger quarter. U.S. Bancorp's 1.54 sat at the 14.8% position among 27 overseas financial stocks, in the smaller quarter.

This is not because the two companies' numbers differ. It is because the groups they stand in differ. Swap the groups and the bands swap too. Put KakaoBank's 1.50 on the 27 overseas financials and it lands at 14.8%, in the smaller quarter; put U.S. Bancorp's 1.54 on the 44 Korean financials and it lands at 86.4%, in the larger quarter.

It splits within a single stock as well. Put KakaoBank's same 1.50 on the 198 Korean stocks that have a PBR and it sits at the 44.4% position, in the lower middle. A value in the larger quarter of its sector group falls in the lower middle of the market group. Both sentences appear side by side on the same page.

This article records a check of whether that is an exception or a common occurrence. The short answer: it was common.

On a Jupick stock page, three kinds of yardsticks show where a metric stands. The first is the market yardstick, which lines up every stock in the same currency zone. “Every stock” here is not every listed stock but every stock on Jupick's list quoted in KRW, or every one quoted in US dollars.

The second is the sector yardstick, which gathers only the same sector within the same currency zone. The third lines up a group in the same sector but the opposite currency zone. For a Korean financial stock, that group is overseas financials; for an overseas financial stock, it is Korean financials.

The three yardsticks use exactly the same formula. Count how many values are smaller than the one in question, divide by the total count to get a percentage, and split into four bands at 25, 50 and 75. The only thing that changes is who is in the lineup.

When the sample is too small, no band name is given at all. The minimum is 30 for the market yardstick and 8 for the sector and currency-zone yardsticks. A yardstick that falls short drops out with no band name. If only the sector side is short, the market yardstick's band stays and only the sector yardstick's band disappears.

Jupick took the major stocks stored on September 21, 2026 and placed each of six comparison metrics on all three yardsticks at once. Only cases where all three yardsticks cleared the minimum sample, producing three band names, were counted. There were 1,711 such cases, covering 328 stocks (82.0%).

All three band names matched in 533 cases, 31.2% of the total. Two different bands appeared in 941 cases, 55.0%, and all three differed in 237 cases, 13.9%. Together, in 1,178 cases, 68.8%, the answers did not converge on one.

At the stock level it is even clearer. Of the 328 stocks with at least one metric covered by all three yardsticks, 321 saw the band split at least once. That is 97.9%. Only seven stocks got a single answer on every metric covered by all three yardsticks.

Comparing yardsticks two at a time shows which axis moves things more. The market and sector yardsticks pointed to different bands in 850 of 2,043 cases, 41.6%. Switching only the currency zone within the same sector did so in 958 of 1,711 cases, 56.0%. Crossing currency zones changed the band more often than narrowing to a sector.

Counted separately, the six metrics did not split at the same rate. Operating margin split in 224 of 299 cases, 74.9%; PBR in 216 of 290, 74.5%; and ROE in 216 of 291, 74.2%.

PER (price to earnings ratio) split in 205 of 296 cases, 69.3%, and dividend yield in 170 of 252, 67.5%.

The debt ratio shifted least: 147 of 283 cases, 51.9%, the only one of the six near half.

This measurement alone does not settle why the debt ratio shifted less. The difference comes from a single snapshot, and finding the cause would take a separate look at the distribution by sector. What is certain for now is only the order: the effect of switching yardsticks depends on which metric is being read, and the gap between the largest and smallest rates is 23 percentage points.

Here is one of the 237 cases where the three yardsticks pointed three ways, exactly as recorded: the 18.2% operating margin of US insurer Progressive.

Against all major overseas stocks, it sits at the 32.0% position, in the lower middle. Narrowed to 28 overseas financials, it sits at 7.1%, in the smaller quarter. Against 18 Korean stocks in the same sector, it sits at 88.9%, in the larger quarter.

One number, three band names: lower middle, smaller quarter and larger quarter at once. The three statements do not contradict each other; each simply refers to a different group.

One point needs to be clear. Landing in the larger quarter does not mean priced high or good, and landing in the smaller quarter does not mean priced low or bad. That is why Jupick's band names say larger and smaller instead of top and bottom. A position is a position, not an assessment.

Two things are worth checking before reading a band name. The first is who is actually in the group.

For example, the Korean financial group is not only banks and insurers. Holding companies and commodity brokers sit in the same classification. A PBR level natural for banks and one natural for holding companies stand mixed in one line. It also means that a sector group with the same name may not be made up the same way in Korea and overseas.

The second is the sample size. The sector yardstick's minimum is 8, and in a group of exactly 8, one stock moves the percentage by 12.5 percentage points. A change of a single rank can change the band name.

That did happen. DuPont's 14.2% operating margin sat at the 0.0% position among 8 overseas materials stocks, meaning it was the smallest value. The same value placed on 19 Korean materials stocks sat at 78.9%. Being at the bottom of a line of 8 does not conflict with being in the upper part of a line of 19. Both statements hold within their own group. That is why Jupick always shows the sample size next to the band name.

With the measurement in hand, Jupick reviewed its display rules again and decided to keep three of them.

First, readers do not choose the yardstick themselves. Letting them choose invites switching groups until the desired band shows up. In a structure where answers split 68.8% of the time, that approach almost always works. So Jupick puts all three yardsticks on one page and lets the fact that they differ be read for what it is.

Second, a band name is used only with the yardstick name and sample size attached. Taken alone, “larger quarter” refers to no group at all.

Third, in the section that sets the Korean yardstick against the overseas one, metrics where both yardsticks pointed to the same band are not listed line by line; only their count is given. That section answers one question, “does crossing regions change the position?”, so a count is enough for metrics that did not change. The section that sets the market and sector yardsticks side by side is not folded this way and shows every metric.

If there is a reading order to suggest, it is this: look at the yardstick name first, then the sample size, then the band name. Reverse the order and start with the band name, and the first two slip out of view.

KakaoBank's PBR of 1.50 and U.S. Bancorp's PBR of 1.54 are nearly the same number, yet they sat in opposite bands within their own sector groups. Swapping the groups swapped the bands too.

Jupick placed six metrics of its major stocks on three yardsticks at once and counted 1,711 cases. All three answers matched in 533, or 31.2%, and the remaining 1,178, or 68.8%, split. There were also 237 that split three ways.

By stock, 321 of 328, or 97.9%, split at least once somewhere. Seven stocks got a single answer on every metric covered by all three yardsticks.

Split rates differed by metric. Operating margin was highest at 74.9% and the debt ratio lowest at 51.9%. By axis, crossing currency zones changed the band more often than narrowing to a sector.

So when reading a band name on a stock page, look at the yardstick name and sample size next to it every time. The same value landing in different bands is not a data error; the groups are different.

This content is for information only and is not investment advice. Jupick gives no trading advice and no price forecasts, and it does not use the band a metric falls in to call a stock priced high or low. The figures cited were measured on the major stocks Jupick held on September 21, 2026. That list is drawn only from the largest companies by market cap, so it does not represent the whole market, and it changes with updates.
