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 GD 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: May 11, 2023
End date: May 8, 2024
a = 3.7406
b = 0.0011
s = 0.0220
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0011) – 1
= 47.15%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0220) – 1
= 9.22%

Top border of price channel:
Exp(Y1,009)
= Exp(a + b × X1,009 + 2 × s)
= Exp(a + b × 1,463 + 2 × s)
= Exp(3.7406 + 0.0011 × 1,463 + 2 × 0.0220)
= Exp(5.3329)
= $207.03
Bottom border of price channel:
Exp(Y1,009)
= Exp(a + b × X1,009 – 2 × s)
= Exp(a + b × 1,463 – 2 × s)
= Exp(3.7406 + 0.0011 × 1,463 – 2 × 0.0220)
= Exp(5.2447)
= $189.56

= Exp(a + b × 1,826 + 2 × s)
= Exp(3.7406 + 0.0011 × 1,826 + 2 × 0.0220)
= Exp(5.7170)
= $303.99
Bottom border of price channel:
Exp(Y1,258)
= Exp(a + b × X1,258 – 2 × s)
= Exp(a + b × 1,826 – 2 × s)
= Exp(3.7406 + 0.0011 × 1,826 – 2 × 0.0220)
= Exp(5.6288)
= $278.34
