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 NSC 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: January 7, 2021
End date: November 30, 2023
a = 5.6243
b = -0.0002
s = 0.0702
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0002) – 1
= -8.24%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0702) – 1
= 32.40%

Top border of price channel:
Exp(Y194)
= Exp(a + b × X194 + 2 × s)
= Exp(a + b × 281 + 2 × s)
= Exp(5.6243 + -0.0002 × 281 + 2 × 0.0702)
= Exp(5.6984)
= $298.38
Bottom border of price channel:
Exp(Y194)
= Exp(a + b × X194 – 2 × s)
= Exp(a + b × 281 – 2 × s)
= Exp(5.6243 + -0.0002 × 281 – 2 × 0.0702)
= Exp(5.4177)
= $225.36

Top border of price channel:
Exp(Y923)
= Exp(a + b × X923 + 2 × s)
= Exp(a + b × 1,338 + 2 × s)
= Exp(5.6243 + -0.0002 × 1,338 + 2 × 0.0702)
= Exp(5.4493)
= $232.59
Bottom border of price channel:
Exp(Y923)
= Exp(a + b × X923 – 2 × s)
= Exp(a + b × 1,338 – 2 × s)
= Exp(5.6243 + -0.0002 × 1,338 – 2 × 0.0702)
= Exp(5.1686)
