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 SONO 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: February 4, 2021
End date: November 24, 2023

a = 4.0528

b = -0.0012

s = 0.1419

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0012) – 1
= -35.18%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.1419) – 1
= 76.39%

February 4, 2021 calculations

Top border of price channel:

Exp(Y194)
= Exp(a + b × X194 + 2 × s)
= Exp(a + b × 281 + 2 × s)
= Exp(4.0528 + -0.0012 × 281 + 2 × 0.1419)
= Exp(4.0028)
= $54.75

Bottom border of price channel:

Exp(Y194)
= Exp(a + b × X194 – 2 × s)
= Exp(a + b × 281 – 2 × s)
= Exp(4.0528 + -0.0012 × 281 – 2 × 0.1419)
= Exp(3.4353)
= $31.04

November 24, 2023 calculations

Top border of price channel:

Exp(Y900)
= Exp(a + b × X900 + 2 × s)
= Exp(a + b × 1,304 + 2 × s)
= Exp(4.0528 + -0.0012 × 1,304 + 2 × 0.1419)
= Exp(2.7878)
= $16.25

Bottom border of price channel:

Exp(Y900)
= Exp(a + b × X900 – 2 × s)
= Exp(a + b × 1,304 – 2 × s)
= Exp(4.0528 + -0.0012 × 1,304 – 2 × 0.1419)
= Exp(2.2203)
= $9.21

a = 3.2411

b = -0.0004

s = 0.1490

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0004) – 1
= -13.09%

Price channel spread:

= 81.51%

April 26, 2022 calculations

Top border of price channel:

Exp(Y502)
= Exp(a + b × X502 + 2 × s)
= Exp(a + b × 727 + 2 × s)
= Exp(3.2411 + -0.0004 × 727 + 2 × 0.1490)
= Exp(3.2598)
= $26.04

Bottom border of price channel:

Exp(Y502)
= Exp(a + b × X502 – 2 × s)
= Exp(a + b × 727 – 2 × s)
= Exp(3.2411 + -0.0004 × 727 – 2 × 0.1490)
= Exp(2.6636)
= $14.35

April 2, 2025 calculations

Top border of price channel:

Exp(Y1,238)
= Exp(a + b × X1,238 + 2 × s)
= Exp(a + b × 1,799 + 2 × s)
= Exp(3.2411 + -0.0004 × 1,799 + 2 × 0.1490)
= Exp(2.8478)
= $17.25

Bottom border of price channel:

Exp(Y1,238)
= Exp(a + b × X1,238 – 2 × s)
= Exp(a + b × 1,799 – 2 × s)
