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 DECK 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: December 20, 2024
End date: April 23, 2025

a = 17.8160

b = -0.0073

s = 0.0760

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0073) – 1
= -92.98%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0760) – 1
= 35.51%

December 20, 2024 calculations

Top border of price channel:

Exp(Y1,170)
= Exp(a + b × X1,170 + 2 × s)
= Exp(a + b × 1,696 + 2 × s)
= Exp(17.8160 + -0.0073 × 1,696 + 2 × 0.0760)
= Exp(5.6247)
= $277.18

Bottom border of price channel:

Exp(Y1,170)
= Exp(a + b × X1,170 – 2 × s)
= Exp(a + b × 1,696 – 2 × s)
= Exp(17.8160 + -0.0073 × 1,696 – 2 × 0.0760)
= Exp(5.3208)
= $204.55

April 23, 2025 calculations

Top border of price channel:

Exp(Y1,252)
= Exp(a + b × X1,252 + 2 × s)
= Exp(a + b × 1,820 + 2 × s)
= Exp(17.8160 + -0.0073 × 1,820 + 2 × 0.0760)
= Exp(4.7222)
= $112.42

Bottom border of price channel:

Exp(Y1,252)
= Exp(a + b × X1,252 – 2 × s)
= Exp(a + b × 1,820 – 2 × s)
= Exp(17.8160 + -0.0073 × 1,820 – 2 × 0.0760)
= Exp(4.4183)
= $82.96
