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 SANM 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: September 12, 2023
End date: February 28, 2025

a = 2.6369

b = 0.0010

s = 0.0583

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0010) – 1
= 45.00%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0583) – 1
= 26.28%

September 12, 2023 calculations

Top border of price channel:

Exp(Y850)
= Exp(a + b × X850 + 2 × s)
= Exp(a + b × 1,233 + 2 × s)
= Exp(2.6369 + 0.0010 × 1,233 + 2 × 0.0583)
= Exp(4.0088)
= $55.08

Bottom border of price channel:

Exp(Y850)
= Exp(a + b × X850 – 2 × s)
= Exp(a + b × 1,233 – 2 × s)
= Exp(2.6369 + 0.0010 × 1,233 – 2 × 0.0583)
= Exp(3.7754)
= $43.62

February 28, 2025 calculations

Top border of price channel:

Exp(Y1,217)
= Exp(a + b × X1,217 + 2 × s)
= Exp(a + b × 1,768 + 2 × s)
= Exp(2.6369 + 0.0010 × 1,768 + 2 × 0.0583)
= Exp(4.5534)
= $94.96

Bottom border of price channel:

Exp(Y1,217)
= Exp(a + b × X1,217 – 2 × s)
= Exp(a + b × 1,768 – 2 × s)
= Exp(2.6369 + 0.0010 × 1,768 – 2 × 0.0583)
= Exp(4.3201)
= $75.20

a = 7.6767

b = -0.0019

s = 0.0487

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0019) – 1
= -49.28%

Price channel spread:

Exp(4 × s) – 1

Top border of price channel:

Exp(Y1,187)
= Exp(a + b × X1,187 + 2 × s)
= Exp(a + b × 1,724 + 2 × s)
= Exp(7.6767 + -0.0019 × 1,724 + 2 × 0.0487)
= Exp(4.5674)
= $96.29

Bottom border of price channel:
