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 ROST 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: February 17, 2022
End date: February 5, 2025
a = 3.9760
b = 0.0006
s = 0.0842
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0006) – 1
= 26.09%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0842) – 1
= 40.06%

Top border of price channel:
Exp(Y456)
= Exp(a + b × X456 + 2 × s)
= Exp(a + b × 659 + 2 × s)
= Exp(3.9760 + 0.0006 × 659 + 2 × 0.0842)
= Exp(4.5630)
= $95.87
Bottom border of price channel:
Exp(Y456)
= Exp(a + b × X456 – 2 × s)
= Exp(a + b × 659 – 2 × s)
= Exp(3.9760 + 0.0006 × 659 – 2 × 0.0842)
= Exp(4.2261)
= $68.45

= Exp(5.2514)
= $190.84
Bottom border of price channel:
Exp(Y1,199)
= Exp(a + b × X1,199 – 2 × s)
= Exp(a + b × 1,743 – 2 × s)
