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 LIN 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: June 9, 2026
End date: October 1, 2026
a = 6.6414
b = -0.0012
s = 0.0213
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0012) – 1
= -35.40%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0213) – 1
= 8.90%

Top border of price channel:
Exp(Y213)
= Exp(a + b × X213 + 2 × s)
= Exp(a + b × 309 + 2 × s)
= Exp(6.6414 + -0.0012 × 309 + 2 × 0.0213)
= Exp(6.3142)
= $552.37
Bottom border of price channel:
Exp(Y213)
= Exp(a + b × X213 – 2 × s)
= Exp(a + b × 309 – 2 × s)
= Exp(6.6414 + -0.0012 × 309 – 2 × 0.0213)
= Exp(6.2289)
= $507.22

Top border of price channel:
Exp(Y292)
= Exp(a + b × X292 + 2 × s)
= Exp(a + b × 423 + 2 × s)
= Exp(6.6414 + -0.0012 × 423 + 2 × 0.0213)
= Exp(6.1778)
= $481.91
Bottom border of price channel:
Exp(Y292)
= Exp(a + b × X292 – 2 × s)
= Exp(a + b × 423 – 2 × s)
= Exp(6.6414 + -0.0012 × 423 – 2 × 0.0213)
= Exp(6.0925)
= $442.52

Secondary Trend
Start date: September 16, 2026
End date: October 14, 2026
a = 5.0865
b = 0.0026
s = 0.0069
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0026) – 1
= 153.71%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0069) – 1
= 2.80%
September 16, 2026 calculations
Top border of price channel:
Exp(Y281)
= Exp(a + b × X281 + 2 × s)
= Exp(a + b × 408 + 2 × s)
= Exp(5.0865 + 0.0026 × 408 + 2 × 0.0069)
= Exp(6.1410)
= $464.54
Bottom border of price channel:
Exp(Y281)
= Exp(a + b × X281 – 2 × s)
= Exp(a + b × 408 – 2 × s)
= Exp(5.0865 + 0.0026 × 408 – 2 × 0.0069)
= Exp(6.1134)
= $451.89
