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 SHC 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 16, 2022
End date: August 11, 2023
a = -0.2384
b = 0.0034
s = 0.2350
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0034) – 1
= 240.45%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.2350) – 1
= 155.98%

Top border of price channel:
Exp(Y457)
= Exp(a + b × X457 + 2 × s)
= Exp(a + b × 665 + 2 × s)
= Exp(-0.2384 + 0.0034 × 665 + 2 × 0.2350)
= Exp(2.4635)
= $11.75
Bottom border of price channel:
Exp(Y457)
= Exp(a + b × X457 – 2 × s)
= Exp(a + b × 665 – 2 × s)
= Exp(-0.2384 + 0.0034 × 665 – 2 × 0.2350)
= Exp(1.5236)
= $4.59

= Exp(3.5678)
= $35.44
Bottom border of price channel:
Exp(Y683)
= Exp(a + b × X683 – 2 × s)
= Exp(a + b × 994 – 2 × s)
= Exp(-0.2384 + 0.0034 × 994 – 2 × 0.2350)
