### 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 ASTE 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 24, 2020
End date: July 23, 2024

a = 4.4151

b = -0.0005

s = 0.1487

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0005) – 1
= -16.83%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.1487) – 1
= 81.27%

#### November 24, 2020 calculations

Top border of price channel:

Exp(Y339)
= Exp(a + b × X339 + 2 × s)
= Exp(a + b × 489 + 2 × s)
= Exp(4.4151 + -0.0005 × 489 + 2 × 0.1487)
= Exp(4.4657)
= \$86.98

Bottom border of price channel:

Exp(Y339)
= Exp(a + b × X339 – 2 × s)
= Exp(a + b × 489 – 2 × s)
= Exp(4.4151 + -0.0005 × 489 – 2 × 0.1487)
= Exp(3.8708)
= \$47.98

#### July 23, 2024 calculations

Top border of price channel:

Exp(Y1,257)
= Exp(a + b × X1,257 + 2 × s)
= Exp(a + b × 1,826 + 2 × s)
= Exp(4.4151 + -0.0005 × 1,826 + 2 × 0.1487)
= Exp(3.7906)
= \$44.28

Bottom border of price channel:

Exp(Y1,257)
= Exp(a + b × X1,257 – 2 × s)
= Exp(a + b × 1,826 – 2 × s)
= Exp(4.4151 + -0.0005 × 1,826 – 2 × 0.1487)
= Exp(3.1958)
= \$24.43

#### Description

• The primary trend is decreasing.
• The decline rate of the primary trend is 16.83% per annum.
• ASTE price at the close of July 23, 2024 was \$34.95 and was inside the primary price channel.

### Secondary Trend

Start date: March 4, 2022
End date: July 23, 2024

a = 3.9326

b = -0.0002

s = 0.1290

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0002) – 1
= -6.45%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.1290) – 1
= 67.52%

#### March 4, 2022 calculations

Top border of price channel:

Exp(Y659)
= Exp(a + b × X659 + 2 × s)
= Exp(a + b × 954 + 2 × s)
= Exp(3.9326 + -0.0002 × 954 + 2 × 0.1290)
= Exp(4.0163)
= \$55.50

Bottom border of price channel:

Exp(Y659)
= Exp(a + b × X659 – 2 × s)
= Exp(a + b × 954 – 2 × s)
= Exp(3.9326 + -0.0002 × 954 – 2 × 0.1290)
= Exp(3.5004)
= \$33.13

#### July 23, 2024 calculations
