Y: f(industry growth, market position, financial risk), how to survice, success, sustain.
D: external factors affects all companies in a industry, it can be cyclicity of a industry.
Mature industry is safer
Growth industry, should be carefull, very shock at the end of growth stage.
Long term down stage is more buffer for your portfolio.
Remember: like a specific company, the first and the most important is survive in down trend. (Buffer is your friend).

In other theory, Y is total common shares, and be a constant number. But D is demand can be affected by substitute product (fixed income, variabe income inlude other stock), shareholder structure, and shiffted by preference changes, change in valuation, amount of buyers.

Cycle: chaos to clear trend to chaos

In chaos, the market need leader (Authority, BOD, Bigboys). You can put faith on them, if they have big buffer to protect their position from headwind.

Authority&#39;s buffer: usd reserve x inflation x deference in real interest rates (Us vs VN) x Max(T-G, 4%).

Both of over heat and overcold zone are deadzone for them. But becarefull relaxing plan.

National Bank: KPI one target ( natural unemployment rats ~ GDP growth rate) and two enemies (high inflation + over exchange rates change (trilemma))

BOD: buyback or funding from owner.

Bigboys: the first and most important is   foreign funds.
