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: February 1, 2024
End date: July 25, 2024
a = -1.1316
b = 0.0023
s = 0.0509
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0023) – 1
= 131.10%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0509) – 1
= 22.56%

Top border of price channel:
Exp(Y1,137)
= Exp(a + b × X1,137 + 2 × s)
= Exp(a + b × 1,651 + 2 × s)
= Exp(-1.1316 + 0.0023 × 1,651 + 2 × 0.0509)
= Exp(2.7591)
= $15.79
Bottom border of price channel:
Exp(Y1,137)
= Exp(a + b × X1,137 – 2 × s)
= Exp(a + b × 1,651 – 2 × s)
= Exp(-1.1316 + 0.0023 × 1,651 – 2 × 0.0509)
= Exp(2.5557)
= $12.88

= Exp(3.1608)
= $23.59
Bottom border of price channel:
Exp(Y1,257)
= Exp(a + b × X1,257 – 2 × s)
= Exp(a + b × 1,826 – 2 × s)

= Exp(2.9573)
= $19.25
