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 SLAB 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 24, 2021
End date: December 10, 2024
a = 5.2544
b = -0.0003
s = 0.1312
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0003) – 1
= -10.61%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.1312) – 1
= 69.01%

Top border of price channel:
Exp(Y311)
= Exp(a + b × X311 + 2 × s)
= Exp(a + b × 450 + 2 × s)
= Exp(5.2544 + -0.0003 × 450 + 2 × 0.1312)
= Exp(5.3785)
= $216.70
Bottom border of price channel:
Exp(Y311)
= Exp(a + b × X311 – 2 × s)
= Exp(a + b × 450 – 2 × s)
= Exp(5.2544 + -0.0003 × 450 – 2 × 0.1312)
= Exp(4.8538)
= $128.22

= Exp(5.2544 + -0.0003 × 1,715 + 2 × 0.1312)
= Exp(4.9898)
= $146.91
Bottom border of price channel:
Exp(Y1,182)
= Exp(a + b × X1,182 – 2 × s)
= Exp(a + b × 1,715 – 2 × s)
= Exp(5.2544 + -0.0003 × 1,715 – 2 × 0.1312)
= Exp(4.4650)
