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 TJX 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: March 4, 2022
End date: March 5, 2025
a = 3.5177
b = 0.0008
s = 0.0477
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0008) – 1
= 31.75%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0477) – 1
= 21.00%
March 4, 2022 calculations
Top border of price channel:
Exp(Y466)
= Exp(a + b × X466 + 2 × s)
= Exp(a + b × 674 + 2 × s)
= Exp(3.5177 + 0.0008 × 674 + 2 × 0.0477)
= Exp(4.1222)
= $61.69
Bottom border of price channel:
Exp(Y466)
= Exp(a + b × X466 – 2 × s)
= Exp(a + b × 674 – 2 × s)
= Exp(3.5177 + 0.0008 × 674 – 2 × 0.0477)
= Exp(3.9316)
= $50.99

Top border of price channel:
Exp(Y1,218)
= Exp(a + b × X1,218 + 2 × s)
= Exp(a + b × 1,771 + 2 × s)
= Exp(3.5177 + 0.0008 × 1,771 + 2 × 0.0477)
= Exp(4.9508)
= $141.29
Bottom border of price channel:
Exp(Y1,218)
= Exp(a + b × X1,218 – 2 × s)
= Exp(a + b × 1,771 – 2 × s)
= Exp(3.5177 + 0.0008 × 1,771 – 2 × 0.0477)
= Exp(4.7602)
= $116.77
