Linear Regression Model

Model equation:
Yi = α + β × Xi + εi

Top border of price channel:
Exp(Yi) = Exp(a + b × Xi + 2 × s)

Bottom border of price channel:
Exp(Yi) = Exp(a + b × Xi – 2 × s)

where:

i - observation number
Yi - natural logarithm of WMG price
Xi - time index, 1 day interval
σ - standard deviation of εi
a - estimator of α
b - estimator of β
s - estimator of σ
Exp() - calculates the exponent of e


Primary Trend

Start date: February 11, 2025
End date: June 20, 2025

a = 7.8488

b = -0.0025

s = 0.0321

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0025) – 1
= -60.52%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0321) – 1
= 13.68%

February 11, 2025 calculations

Top border of price channel:

Exp(Y1,158)
= Exp(a + b × X1,158 + 2 × s)
= Exp(a + b × 1,685 + 2 × s)
= Exp(7.8488 + -0.0025 × 1,685 + 2 × 0.0321)
= Exp(3.6225)
= $37.43

Bottom border of price channel:

Exp(Y1,158)
= Exp(a + b × X1,158 – 2 × s)
= Exp(a + b × 1,685 – 2 × s)
= Exp(7.8488 + -0.0025 × 1,685 – 2 × 0.0321)
= Exp(3.4942)
= $32.92

June 20, 2025 calculations

Top border of price channel:

Exp(Y1,247)
= Exp(a + b × X1,247 + 2 × s)
= Exp(a + b × 1,814 + 2 × s)
= Exp(7.8488 + -0.0025 × 1,814 + 2 × 0.0321)
= Exp(3.2940)
= $26.95

Bottom border of price channel:

Exp(Y1,247)
= Exp(a + b × X1,247 – 2 × s)
= Exp(a + b × 1,814 – 2 × s)
= Exp(7.8488 + -0.0025 × 1,814 – 2 × 0.0321)
= Exp(3.1657)
= $23.71
