value of shares

I have an important question related to subsidiary business.

Is it true that the main element that change the value of any business (mainly subsidiary) is market value of its shares which obviously increases by customer loyalty and good reputation but they depend upon several factors like:

1) New shares are issued in market
2) shares issued at premium
3) Post-acquisition Profits
4) Fair value adjustments like Revaluation of Non-current assets
5) Intangible assets being purchased
6) Bidding or Takeovers
7) New R&D initiatives
8) Business partnership or ventures

Are there any more factors that could increase or decrease the market value of shares of subsidiary business? Please define them.

Thanks
