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 QLYS 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: November 3, 2023
End date: November 5, 2024
a = 7.1392
b = -0.0014
s = 0.0567
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0014) – 1
= -40.17%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0567) – 1
= 25.44%

Top border of price channel:
Exp(Y905)
= Exp(a + b × X905 + 2 × s)
= Exp(a + b × 1,311 + 2 × s)
= Exp(7.1392 + -0.0014 × 1,311 + 2 × 0.0567)
= Exp(5.4073)
= $223.03
Bottom border of price channel:
Exp(Y905)
= Exp(a + b × X905 – 2 × s)
= Exp(a + b × 1,311 – 2 × s)
= Exp(7.1392 + -0.0014 × 1,311 – 2 × 0.0567)
= Exp(5.1807)
= $177.80

Top border of price channel:
Exp(Y1,157)
= Exp(a + b × X1,157 + 2 × s)
= Exp(a + b × 1,679 + 2 × s)
= Exp(7.1392 + -0.0014 × 1,679 + 2 × 0.0567)
= Exp(4.8893)
= $132.87
Bottom border of price channel:
Exp(Y1,157)
= Exp(a + b × X1,157 – 2 × s)
= Exp(a + b × 1,679 – 2 × s)
= Exp(7.1392 + -0.0014 × 1,679 – 2 × 0.0567)
= Exp(4.6627)
= $105.92
