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 GRMN 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: August 26, 2022
End date: October 28, 2025
a = 3.6463
b = 0.0011
s = 0.0745
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0011) – 1
= 47.70%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0745) – 1
= 34.70%

Top border of price channel:
Exp(Y428)
= Exp(a + b × X428 + 2 × s)
= Exp(a + b × 620 + 2 × s)
= Exp(3.6463 + 0.0011 × 620 + 2 × 0.0745)
= Exp(4.4577)
= $86.29
Bottom border of price channel:
Exp(Y428)
= Exp(a + b × X428 – 2 × s)
= Exp(a + b × 620 – 2 × s)
= Exp(3.6463 + 0.0011 × 620 – 2 × 0.0745)
= Exp(4.1598)
= $64.06
