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 IT 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

End date: March 31, 2025
a = 14.6078
b = -0.0047
s = 0.0181
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0047) – 1
= -81.98%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0181) – 1
= 7.53%

Top border of price channel:
Exp(Y1,214)
= Exp(a + b × X1,214 + 2 × s)
= Exp(a + b × 1,765 + 2 × s)
= Exp(14.6078 + -0.0047 × 1,765 + 2 × 0.0181)
= Exp(6.3587)
= $577.47
Bottom border of price channel:
Exp(Y1,214)
= Exp(a + b × X1,214 – 2 × s)
= Exp(a + b × 1,765 – 2 × s)
= Exp(14.6078 + -0.0047 × 1,765 – 2 × 0.0181)
= Exp(6.2861)
= $537.04
