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 TGNA 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 7, 2024
End date: April 2, 2025
a = 1.4117
b = 0.0009
s = 0.0663
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0009) – 1
= 39.13%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0663) – 1
= 30.39%

Top border of price channel:
Exp(Y855)
= Exp(a + b × X855 + 2 × s)
= Exp(a + b × 1,241 + 2 × s)
= Exp(1.4117 + 0.0009 × 1,241 + 2 × 0.0663)
= Exp(2.6671)
= $14.40
Bottom border of price channel:
Exp(Y855)
= Exp(a + b × X855 – 2 × s)
= Exp(a + b × 1,241 – 2 × s)
= Exp(1.4117 + 0.0009 × 1,241 – 2 × 0.0663)
= Exp(2.4018)
= $11.04
