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 SF 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: September 25, 2023
End date: November 5, 2024
a = 2.2531
b = 0.0013
s = 0.0443
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0013) – 1
= 60.01%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0443) – 1
= 19.40%

Top border of price channel:
Exp(Y966)
= Exp(a + b × X966 + 2 × s)
= Exp(a + b × 1,405 + 2 × s)
= Exp(2.2531 + 0.0013 × 1,405 + 2 × 0.0443)
= Exp(4.1513)
= $63.51
Bottom border of price channel:
Exp(Y966)
= Exp(a + b × X966 – 2 × s)
= Exp(a + b × 1,405 – 2 × s)
= Exp(2.2531 + 0.0013 × 1,405 – 2 × 0.0443)
= Exp(3.9740)
= $53.19

Exp(Y1,247)
= Exp(a + b × X1,247 + 2 × s)
= Exp(a + b × 1,812 + 2 × s)
= Exp(2.2531 + 0.0013 × 1,812 + 2 × 0.0443)
= Exp(4.6754)
= $107.28
Bottom border of price channel:
Exp(Y1,247)
= Exp(a + b × X1,247 – 2 × s)
= Exp(a + b × 1,812 – 2 × s)
= Exp(2.2531 + 0.0013 × 1,812 – 2 × 0.0443)
= Exp(4.4981)
= $89.85
