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 SPTN 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: March 3, 2022
End date: August 14, 2024
a = 3.8676
b = -0.0006
s = 0.0740
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0006) – 1
= -20.66%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0740) – 1
= 34.44%

Top border of price channel:
Exp(Y464)
= Exp(a + b × X464 + 2 × s)
= Exp(a + b × 672 + 2 × s)
= Exp(3.8676 + -0.0006 × 672 + 2 × 0.0740)
= Exp(3.5895)
= $36.21
Bottom border of price channel:
Exp(Y464)
= Exp(a + b × X464 – 2 × s)
= Exp(a + b × 672 – 2 × s)
= Exp(3.8676 + -0.0006 × 672 – 2 × 0.0740)
= Exp(3.2935)
= $26.94

Top border of price channel:
Exp(Y1,079)
= Exp(a + b × X1,079 + 2 × s)
= Exp(a + b × 1,567 + 2 × s)
= Exp(3.8676 + -0.0006 × 1,567 + 2 × 0.0740)
= Exp(3.0220)
= $20.53
Bottom border of price channel:
Exp(Y1,079)
= Exp(a + b × X1,079 – 2 × s)
= Exp(a + b × 1,567 – 2 × s)
= Exp(3.8676 + -0.0006 × 1,567 – 2 × 0.0740)
= Exp(2.7260)
= $15.27
