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 GMED 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: April 21, 2021
End date: May 7, 2024

a = 4.6603

b = -0.0004

s = 0.0872

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0004) – 1
= -13.95%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0872) – 1
= 41.75%

April 21, 2021 calculations

Top border of price channel:

Exp(Y491)
= Exp(a + b × X491 + 2 × s)
= Exp(a + b × 713 + 2 × s)
= Exp(4.6603 + -0.0004 × 713 + 2 × 0.0872)
= Exp(4.5411)
= $93.80

Bottom border of price channel:

Exp(Y491)
= Exp(a + b × X491 – 2 × s)
= Exp(a + b × 713 – 2 × s)
= Exp(4.6603 + -0.0004 × 713 – 2 × 0.0872)
= Exp(4.1922)
= $66.17

Top border of price channel:

Exp(Y1,257)
= Exp(a + b × X1,257 + 2 × s)
= Exp(a + b × 1,825 + 2 × s)
= Exp(4.6603 + -0.0004 × 1,825 + 2 × 0.0872)
= Exp(4.0833)
= $59.34

Bottom border of price channel:

Exp(Y1,257)
= Exp(a + b × X1,257 – 2 × s)
= Exp(a + b × 1,825 – 2 × s)
= Exp(4.6603 + -0.0004 × 1,825 – 2 × 0.0872)
= Exp(3.7344)
= $41.86

a = 2.6541

b = 0.0007

s = 0.0574

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0007) – 1
= 31.03%
