Week by week · International Gemological Institute Ltd.

The last ninety sessions read a week at a time: each week's open, high, low and close, how much it gained or lost, the slope and angle the weeks make, which patterns in the library the weekly candles match, and what the next four weeks look like by the arithmetic of this name's own record. A reading of the past, never a forecast.

The reading

20 weeks: -13.74% from the first open to the last close, an average -0.76% a week

5 weeks closed above the week before, 14 below. The median week moved -0.48%, and a typical week's move either side of the average was 2.75%. The best week was +5.30% (week of 2026-09-14), the worst -5.63% (week of 2026-09-28). The second half of the window ran -0.95% a week against -0.54% in the first: the move has been losing pace.

The slope: closes falling 0.81% a week, angle -39°, R² 0.84

A straight line through the weekly closes (on a log scale) falls 0.81% a week. On the page's fixed scale, where 1% a week is 45°, that is -39°. R² 0.84 says how closely the weeks hug the line: close to 1 is a clean, steady trend. The line through the weekly highs runs -0.79% a week (-38°), the one through the lows -0.76% (-37°).

The shape: falling channel

Highs and lows both sliding at about the same pace: a steady downtrend. Week on week, 5 of 19 weeks made a higher high and 9 of 19 a higher low. The gap between the two lines went from 6.7% to 6.1%.

The patterns on the weekly candles: 7 in play, 7 with a record worth counting

Trend line: slope, length, strength (just completed, down): four weeks later it went its way 1885 of 3356 times across 1917 names; Gap at the open (just completed, up): four weeks later it went its way 12 of 28 times on this name; Move of X% within M candles (just completed, down): four weeks later it went its way 11 of 28 times on this name; Hammer (completed recently, up): four weeks later it went its way 1845 of 4681 times across 2054 names; Evening star (completed recently, down): four weeks later it went its way 1712 of 3099 times across 1787 names; Lower highs and lower lows (completed recently, down): four weeks later it went its way 3 of 6 times on this name.

Four weeks on, by the arithmetic: middle of the readings 310.28 (-2.92%), 45% chance the close is higher

From the last close of 319.60: if the window's average week carried on it would print 309.62 (-3.12%); if the close line's slope carried on, 309.38 (-3.20%). Four in five of this name's earlier four-week windows ended between 290.39 and 339.22 (-9.14% to +6.14%). The middle figure is the plain average of those three centres. None of these is a level the price is going to; they are what the record prints.

Our arithmetic from stored candles: no recommendation, no forecast of any price. The paths below are what the numbers would print if the past simply carried on, and the range is where this name's own earlier moves ended. The decision, and the risk, are yours.

The ranges and the chance are counted from this name's own earlier windows of the same length over the last 95 weeks on file; the chance is pulled toward the record of any weekly pattern in play. The middle figure is the plain average of the three centres: the average-week path, the slope path and the median of the earlier windows.

Our arithmetic from stored candles: no recommendation, no forecast of any price. The paths below are what the numbers would print if the past simply carried on, and the range is where this name's own earlier moves ended. The decision, and the risk, are yours.

How week by week is counted

1. The weeks

The last ninety sessions (the window the stock page draws), adjusted for splits and bonuses, grouped by calendar week. A week's open is its first session's open, its close the last session's close, its high and low the extremes of its sessions. The first week can be cut short when the window starts mid-week; it is marked, and its change on the week before is left out of the averages.

2. The growth

Each week's change from open to close, and from the week before's close to its own. The averages are over whole weeks: the mean and median weekly change, the spread either side of the mean, the up and down weeks, the best and the worst, and whether the second half of the window moved faster or slower than the first.

3. The slope and the angle

A least-squares straight line through the weekly closes, and one each through the weekly highs and lows, fitted on a log scale so a slope reads as a steady percentage a week. The angle puts that slope on a fixed scale where 1% a week is 45°, so two names can be compared; the angle a chart happens to draw depends only on how the axes are stretched. R² (0 to 1) says how closely the weeks hug the close line. The two outer lines name the shape: a rising or falling channel, a wedge, a widening or narrowing range, a triangle.

4. The patterns

Every pattern in the library run on this name's weekly candles (about two years on file). Those that completed on the latest week, completed recently, or are building are listed with what followed their earlier hits four weeks on: on this name when it has five or more, else across every name the library has seen them on.

5. The next four weeks

Three readings for each week ahead, all from the last close: the window's average week compounded; the close line's slope carried on; and the 20th to 80th percentile of this name's own earlier moves over that many weeks (the last 104 weeks), with its median. The middle of the readings is the plain average of the three centres. The chance the close is higher is the same base rate and pattern evidence the outlook uses. These are what the record prints if the past simply carried on; nothing here is a forecast, and the ranges show how far it has strayed before.
