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 STBA 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: July 17, 2024
End date: August 21, 2025
a = 4.0817
b = -0.0003
s = 0.0488
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0003) – 1
= -9.52%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0488) – 1
= 21.57%

Top border of price channel:
Exp(Y965)
= Exp(a + b × X965 + 2 × s)
= Exp(a + b × 1,402 + 2 × s)
= Exp(4.0817 + -0.0003 × 1,402 + 2 × 0.0488)
= Exp(3.7951)
= $44.48
Bottom border of price channel:
Exp(Y965)
= Exp(a + b × X965 – 2 × s)
= Exp(a + b × 1,402 – 2 × s)
= Exp(4.0817 + -0.0003 × 1,402 – 2 × 0.0488)
= Exp(3.5998)
= $36.59

Top border of price channel:
Exp(Y1,240)
= Exp(a + b × X1,240 + 2 × s)
= Exp(a + b × 1,802 + 2 × s)
= Exp(4.0817 + -0.0003 × 1,802 + 2 × 0.0488)
= Exp(3.6855)
= $39.86
Bottom border of price channel:
Exp(Y1,240)
= Exp(a + b × X1,240 – 2 × s)
= Exp(a + b × 1,802 – 2 × s)
= Exp(4.0817 + -0.0003 × 1,802 – 2 × 0.0488)
= Exp(3.4902)
= $32.79
