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 FIZZ 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 2, 2021
End date: November 20, 2024

a = 3.7359

b = 0.0001

s = 0.0769

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0001) – 1
= 2.02%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0769) – 1
= 36.03%

February 2, 2021 calculations

Top border of price channel:

Exp(Y300)
= Exp(a + b × X300 + 2 × s)
= Exp(a + b × 439 + 2 × s)
= Exp(3.7359 + 0.0001 × 439 + 2 × 0.0769)
= Exp(3.9138)
= $50.09

Bottom border of price channel:

Exp(Y300)
= Exp(a + b × X300 – 2 × s)
= Exp(a + b × 439 – 2 × s)
= Exp(3.7359 + 0.0001 × 439 – 2 × 0.0769)
= Exp(3.6061)
= $36.82

November 20, 2024 calculations

Top border of price channel:

Exp(Y1,257)
= Exp(a + b × X1,257 + 2 × s)
= Exp(a + b × 1,826 + 2 × s)
= Exp(3.7359 + 0.0001 × 1,826 + 2 × 0.0769)
= Exp(3.9897)
= $54.04

Bottom border of price channel:

Exp(Y1,257)
= Exp(a + b × X1,257 – 2 × s)
= Exp(a + b × 1,826 – 2 × s)
= Exp(3.7359 + 0.0001 × 1,826 – 2 × 0.0769)
= Exp(3.6820)
= $39.73

a = 0.4825

b = 0.0019

s = 0.0225

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0019) – 1
