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 PSA 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: August 19, 2024
End date: January 13, 2026
a = 6.2427
b = -0.0004
s = 0.0422
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0004) – 1
= -12.37%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0422) – 1
= 18.38%

Top border of price channel:
Exp(Y899)
= Exp(a + b × X899 + 2 × s)
= Exp(a + b × 1,306 + 2 × s)
= Exp(6.2427 + -0.0004 × 1,306 + 2 × 0.0422)
= Exp(5.8545)
= $348.80
Bottom border of price channel:
Exp(Y899)
= Exp(a + b × X899 – 2 × s)
= Exp(a + b × 1,306 – 2 × s)
= Exp(6.2427 + -0.0004 × 1,306 – 2 × 0.0422)
= Exp(5.6857)
= $294.64

= Exp(a + b × 1,818 + 2 × s)
= Exp(6.2427 + -0.0004 × 1,818 + 2 × 0.0422)
= Exp(5.6692)
= $289.81
Bottom border of price channel:
Exp(Y1,250)
= Exp(a + b × X1,250 – 2 × s)
= Exp(a + b × 1,818 – 2 × s)
= Exp(6.2427 + -0.0004 × 1,818 – 2 × 0.0422)
= Exp(5.5005)
= $244.81
