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 DD 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: January 24, 2024
End date: April 9, 2024

a = -0.4056

b = 0.0030

s = 0.0187

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0030) – 1
= 195.98%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0187) – 1
= 7.78%

Top border of price channel:

Exp(Y1,048)
= Exp(a + b × X1,048 + 2 × s)
= Exp(a + b × 1,525 + 2 × s)
= Exp(-0.4056 + 0.0030 × 1,525 + 2 × 0.0187)
= Exp(4.1656)
= $64.43

Bottom border of price channel:

Exp(Y1,048)
= Exp(a + b × X1,048 – 2 × s)
= Exp(a + b × 1,525 – 2 × s)
= Exp(-0.4056 + 0.0030 × 1,525 – 2 × 0.0187)
= Exp(4.0906)
= $59.78

Top border of price channel:

Exp(Y1,100)
= Exp(a + b × X1,100 + 2 × s)
= Exp(a + b × 1,601 + 2 × s)
= Exp(-0.4056 + 0.0030 × 1,601 + 2 × 0.0187)
= Exp(4.3915)
= $80.77

Bottom border of price channel:

Exp(Y1,100)
= Exp(a + b × X1,100 – 2 × s)
= Exp(a + b × 1,601 – 2 × s)
