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 HD 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: July 15, 2025
End date: September 12, 2025

a = 0.9710

b = 0.0028

s = 0.0136

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0028) – 1
= 176.42%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0136) – 1
= 5.59%

Top border of price channel:

Exp(Y1,212)
= Exp(a + b × X1,212 + 2 × s)
= Exp(a + b × 1,764 + 2 × s)
= Exp(0.9710 + 0.0028 × 1,764 + 2 × 0.0136)
= Exp(5.9120)
= $369.44

Bottom border of price channel:

Exp(Y1,212)
= Exp(a + b × X1,212 – 2 × s)
= Exp(a + b × 1,764 – 2 × s)
= Exp(0.9710 + 0.0028 × 1,764 – 2 × 0.0136)
= Exp(5.8576)
= $349.89

= Exp(6.0763)
= $435.43

Bottom border of price channel:

Exp(Y1,254)
= Exp(a + b × X1,254 – 2 × s)
= Exp(a + b × 1,823 – 2 × s)
