How SuperX's value range and price levels are worked out

SuperX shows three figures on a stock page that need a written method: the computed value range, the price levels, and the letters R, D, B, S and T on the one-year chart. This guide gives each rule in full, so a reader can repeat it. None of the three is advice. Each is a method applied to past data.

How is the value range worked out?

The value range asks one question. If the company traded at the middle half of its sector’s price-to-earnings ratios, what price would that give? The steps are these.

1. Take the other companies in the same sector. The company itself is left out.
2. Keep each one whose price-to-earnings ratio is above 0 and up to 100. A company that lost money has no usable ratio. A ratio above 100 usually reflects a near-zero profit, not a high value.
3. Count the companies kept. If none remain, no range is shown. SuperX does not borrow the whole market instead. With 1 to 4 companies the page says it is a small sample, and with exactly one the three ratios are the same, so the range is a single value.
4. Sort the kept ratios. Find the lower quarter point, the median and the upper quarter point. Together the first and last cover the middle half.
5. Take the company’s own earnings per share over its last 12 months.
6. Multiply the three ratios by that figure. The results are the low, middle and high of the range, rounded to two places.

The page then says whether the latest price is below, inside or above the range. If the company made a loss, or has no earnings per share on record, the range is withheld and the page says why.

How many companies get a range?

On 15 November 2026, 347 companies had a positive price-to-earnings ratio. A further 16 ratios were above 100 and were left out of the peer sets. A company with no usable peer gets no range.

What can the value range not tell you?

It does not say what a company is worth. It says only what the sector’s ratios imply for this company’s earnings. Sector peers can differ in size, debt and growth. Earnings can change after the last report. It is not a broker’s target.

How are price levels worked out?

A price level is a price where the share turned back several times in the last 12 months. The rule uses daily highs, lows and closes, adjusted with the same factors as SuperX’s price charts (the exchange’s recorded price adjustments).

1. Drop sessions with no volume. If fewer than 60 sessions remain, no levels are shown.
2. Find the turns. A day is a swing high if its high is the highest of the five sessions before it and the five after it. A swing low is the same test on lows. The last five sessions cannot be turns, because they lack five sessions after them.
3. Measure the 14-session average range: the mean of the last 14 daily true ranges. The true range counts any gap from the previous close.
4. Sort all turns by price. Group turns that lie within half the average range of the group’s mean price.
5. A group needs at least 2 turns to be a level. Its price is the mean of its turns.
6. Score each group. A turn counts 1 today. Its weight halves for every 126 days of age, so older turns count less.
7. Show the highest-scoring level below the latest close and the highest-scoring level above it. At most two rows appear.

Each level shows its price, the number of touches, and the dates of its first and last touch.

What can price levels not tell you?

A level is a dated past fact. It is not a line into the future. A price can pass through a level without pausing, and it can stop at a price that is not a level. A share with fewer than 60 sessions of history, or no repeated turns, has no level.

What do R, D, B, S and T mean on the one-year chart?

The one-year chart marks dated company events inside its own window. Each mark has a letter and a shape, so colour is not the only clue.

Letter	Event
R	A results filing: the latest one in the window
D	An ex-dividend date
B	A bonus issue date
S	A split date
T	A dealing by a director or major holder: the latest ones

Marks that fall too close together to draw apart merge into one mark that shows a count. A dated list of the same events sits under the chart, so the chart does not need hovering. The events come from the company’s notices to the exchange and the exchange’s payout records.

Where do the numbers come from?

The ratios and earnings come from the exchange’s published figures and the company’s filed accounts. Prices and volumes come from the exchange’s daily records. Every figure on the page shows its period, its basis and its source.
