Concept:Stock exchange traders who anticipate price movements and take risks to make profit are called speculators.
Explanation:In the stock exchange market, bulls, bears, and stags are all types of speculators.
A bull speculator expects share prices to rise, so he buys shares now and sells them later at a higher price.
A bear speculator expects share prices to fall, so he sells shares now and buys them back later at a lower price.
A stag speculator applies for new shares and quickly sells them at a premium for a short-term profit.
These dealers are not actuaries, because actuaries deal with insurance and risk calculations.
They are not promoters, because promoters organise the formation of a company.
They are not underwriters, because underwriters guarantee the sale of shares to the public.
Therefore, all three groups are best described as speculators in the stock exchange.
Answer:C. speculators
