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 CLB 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 5, 2021
End date: January 5, 2023
a = 4.0508
b = -0.0010
s = 0.1622
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0010) – 1
= -31.60%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.1622) – 1
= 91.33%

Top border of price channel:
Exp(Y274)
= Exp(a + b × X274 + 2 × s)
= Exp(a + b × 399 + 2 × s)
= Exp(4.0508 + -0.0010 × 399 + 2 × 0.1622)
= Exp(3.9600)
= $52.45
Bottom border of price channel:
Exp(Y274)
= Exp(a + b × X274 – 2 × s)
= Exp(a + b × 399 – 2 × s)
= Exp(4.0508 + -0.0010 × 399 – 2 × 0.1622)
= Exp(3.3111)
= $27.42

Top border of price channel:
Exp(Y778)
= Exp(a + b × X778 + 2 × s)
= Exp(a + b × 1,129 + 2 × s)
= Exp(4.0508 + -0.0010 × 1,129 + 2 × 0.1622)
= Exp(3.2003)
= $24.54
Bottom border of price channel:
Exp(Y778)
= Exp(a + b × X778 – 2 × s)
= Exp(a + b × 1,129 – 2 × s)
= Exp(4.0508 + -0.0010 × 1,129 – 2 × 0.1622)
= Exp(2.5515)
= $12.83

a = 3.4622
b = -0.0003
s = 0.1652
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0003) – 1
