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 GE 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: April 21, 2026
End date: July 7, 2026
a = 4.2842
b = 0.0042
s = 0.0290
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0042) – 1
= 361.29%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0290) – 1
= 12.30%

Top border of price channel:
Exp(Y217)
= Exp(a + b × X217 + 2 × s)
= Exp(a + b × 316 + 2 × s)
= Exp(4.2842 + 0.0042 × 316 + 2 × 0.0290)
= Exp(5.6658)
= $288.81
Bottom border of price channel:
Exp(Y217)
= Exp(a + b × X217 – 2 × s)
= Exp(a + b × 316 – 2 × s)
= Exp(4.2842 + 0.0042 × 316 – 2 × 0.0290)
= Exp(5.5498)
= $257.18

Top border of price channel:
Exp(Y269)
= Exp(a + b × X269 + 2 × s)
= Exp(a + b × 393 + 2 × s)
= Exp(4.2842 + 0.0042 × 393 + 2 × 0.0290)
= Exp(5.9883)
= $398.74
Bottom border of price channel:
Exp(Y269)
= Exp(a + b × X269 – 2 × s)
= Exp(a + b × 393 – 2 × s)
= Exp(4.2842 + 0.0042 × 393 – 2 × 0.0290)
= Exp(5.8723)
= $355.07

a = 5.8144
b = 0.0002
s = 0.0296
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0002) – 1
= 7.09%
Price channel spread:

Top border of price channel:
Exp(Y256)
= Exp(a + b × X256 + 2 × s)
= Exp(a + b × 372 + 2 × s)
= Exp(5.8144 + 0.0002 × 372 + 2 × 0.0296)
= Exp(5.9434)
= $381.23
Bottom border of price channel:
Exp(Y256)
= Exp(a + b × X256 – 2 × s)
= Exp(a + b × 372 – 2 × s)
= Exp(5.8144 + 0.0002 × 372 – 2 × 0.0296)
= Exp(5.8250)
= $338.65
