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 SLVM 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: November 5, 2024
End date: August 22, 2025
a = 7.4225
b = -0.0025
s = 0.0396
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0025) – 1
= -60.53%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0396) – 1
= 17.17%

Top border of price channel:
Exp(Y784)
= Exp(a + b × X784 + 2 × s)
= Exp(a + b × 1,139 + 2 × s)
= Exp(7.4225 + -0.0025 × 1,139 + 2 × 0.0396)
= Exp(4.6007)
= $99.55
Bottom border of price channel:
Exp(Y784)
= Exp(a + b × X784 – 2 × s)
= Exp(a + b × 1,139 – 2 × s)
= Exp(7.4225 + -0.0025 × 1,139 – 2 × 0.0396)
= Exp(4.4423)
= $84.97

Top border of price channel:
Exp(Y982)
= Exp(a + b × X982 + 2 × s)
= Exp(a + b × 1,429 + 2 × s)
= Exp(7.4225 + -0.0025 × 1,429 + 2 × 0.0396)
= Exp(3.8621)
= $47.56
Bottom border of price channel:
Exp(Y982)
= Exp(a + b × X982 – 2 × s)
= Exp(a + b × 1,429 – 2 × s)
= Exp(7.4225 + -0.0025 × 1,429 – 2 × 0.0396)
= Exp(3.7037)
= $40.60
