Why Simulate?
Earnings Yield of a stock to quickly assess if it is cheap or expensive.
Present Value of a stock.
Internal Rate of Return of a stock.
Share Buyback vs. dividend or another investment. Which is most valuable to the remaining shareholders?
Share Issuance for a cash payment that may be invested with uncertain returns.
Stock Swap between two companies.

Stock Returns can be simulated using several different models.
Present Value is used in many of the financial models to compare future and present amounts. Internal Rate of Return (IRR) is also explained here.
Share Buyback is when a company repurchases some of its own shares instead of making a dividend payout or an investment.
Share Issuance is when a company issues new shares to fund an investment or acquire another company.
