Answer:
4) no one individual has an advantage in the marketplace.
Step-by-step explanation:
Strong form efficiency in a market is defined as a situation where prices are already influenced by public and insider information.
No one person or group have an advantage as a result of insider information.
So they can't predict future price movements accurately.
Price is a function of market forces. Fundamental and technical analysis cannot be used as prediction tools.
In this situation no one individual has an advantage in the marketplace.
