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: January 12, 2024
End date: September 6, 2024

a = 4.9690

b = -0.0010

s = 0.0305

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0010) – 1
= -31.80%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0305) – 1
= 12.96%

January 12, 2024 calculations

Top border of price channel:

Exp(Y909)
= Exp(a + b × X909 + 2 × s)
= Exp(a + b × 1,318 + 2 × s)
= Exp(4.9690 + -0.0010 × 1,318 + 2 × 0.0305)
= Exp(3.6482)
= $38.41

Bottom border of price channel:

Exp(Y909)
= Exp(a + b × X909 – 2 × s)
= Exp(a + b × 1,318 – 2 × s)
= Exp(4.9690 + -0.0010 × 1,318 – 2 × 0.0305)
= Exp(3.5264)
= $34.00

Top border of price channel:

Exp(Y1,072)
= Exp(a + b × X1,072 + 2 × s)
= Exp(a + b × 1,556 + 2 × s)
= Exp(4.9690 + -0.0010 × 1,556 + 2 × 0.0305)
= Exp(3.3987)
= $29.92

Bottom border of price channel:

Exp(Y1,072)
= Exp(a + b × X1,072 – 2 × s)
= Exp(a + b × 1,556 – 2 × s)
= Exp(4.9690 + -0.0010 × 1,556 – 2 × 0.0305)
= Exp(3.2769)
= $26.49
