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 SYK 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: June 8, 2022
End date: March 7, 2025
a = 4.7967
b = 0.0007
s = 0.0612
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0007) – 1
= 27.69%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0612) – 1
= 27.73%

Top border of price channel:
Exp(Y549)
= Exp(a + b × X549 + 2 × s)
= Exp(a + b × 796 + 2 × s)
= Exp(4.7967 + 0.0007 × 796 + 2 × 0.0612)
= Exp(5.4522)
= $233.27
Bottom border of price channel:
Exp(Y549)
= Exp(a + b × X549 – 2 × s)
= Exp(a + b × 796 – 2 × s)
= Exp(4.7967 + 0.0007 × 796 – 2 × 0.0612)
= Exp(5.2075)
= $182.63

= Exp(6.1239)
= $456.65
Bottom border of price channel:
Exp(Y1,237)
= Exp(a + b × X1,237 – 2 × s)
= Exp(a + b × 1,799 – 2 × s)
