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 IEX 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: February 1, 2024
End date: July 14, 2025
a = 6.0261
b = -0.0005
s = 0.0662
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0005) – 1
= -15.41%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0662) – 1
= 30.30%

Top border of price channel:
Exp(Y893)
= Exp(a + b × X893 + 2 × s)
= Exp(a + b × 1,296 + 2 × s)
= Exp(6.0261 + -0.0005 × 1,296 + 2 × 0.0662)
= Exp(5.5640)
= $260.86
Bottom border of price channel:
Exp(Y893)
= Exp(a + b × X893 – 2 × s)
= Exp(a + b × 1,296 – 2 × s)
= Exp(6.0261 + -0.0005 × 1,296 – 2 × 0.0662)
= Exp(5.2993)
= $200.20

= Exp(a + b × 1,825 + 2 × s)
= Exp(6.0261 + -0.0005 × 1,825 + 2 × 0.0662)
= Exp(5.3213)
= $204.66
Bottom border of price channel:
Exp(Y1,254)
= Exp(a + b × X1,254 – 2 × s)
= Exp(a + b × 1,825 – 2 × s)
= Exp(6.0261 + -0.0005 × 1,825 – 2 × 0.0662)
= Exp(5.0567)
= $157.07
