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: July 19, 2024

a = 5.2962

b = -0.0003

s = 0.1365

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0003) – 1
= -9.53%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.1365) – 1
= 72.60%

June 24, 2021 calculations

Top border of price channel:

Exp(Y486)
= Exp(a + b × X486 + 2 × s)
= Exp(a + b × 703 + 2 × s)
= Exp(5.2962 + -0.0003 × 703 + 2 × 0.1365)
= Exp(5.3762)
= $216.21

Bottom border of price channel:

Exp(Y486)
= Exp(a + b × X486 – 2 × s)
= Exp(a + b × 703 – 2 × s)
= Exp(5.2962 + -0.0003 × 703 – 2 × 0.1365)
= Exp(4.8304)
= $125.26

July 19, 2024 calculations

Top border of price channel:

Exp(Y1,257)
= Exp(a + b × X1,257 + 2 × s)
= Exp(a + b × 1,824 + 2 × s)
= Exp(5.2962 + -0.0003 × 1,824 + 2 × 0.1365)
= Exp(5.0686)
= $158.95

Bottom border of price channel:

Exp(Y1,257)
= Exp(a + b × X1,257 – 2 × s)
= Exp(a + b × 1,824 – 2 × s)
= Exp(5.2962 + -0.0003 × 1,824 – 2 × 0.1365)
= Exp(4.5228)
= $92.09
