Risk reasoning in investments: The statement "His recent investment in the shares of Company A is only a gamble" implies certain assumptions. Decide which are implicit (I: He may incur a loss on this investment; II: He may also gain from this investment).

Given data

• Statement labels the investment as a 'gamble'.
• Assumption I: Loss is a possible outcome.
• Assumption II: Gain is also a possible outcome.

Concept/Approach
Calling something a 'gamble' presumes uncertainty with meaningful chances of opposite outcomes (profit or loss). If only one outcome were plausible, it would not be a gamble.

Step-by-step reasoning
1) If loss were impossible, the 'gamble' label would be inappropriate.2) If gain were impossible, again the term would not fit (it would be a sure loss, not a gamble).Hence both I and II are necessary to justify the word choice.

Verification/Alternative
Gambling entails two-sided risk. Both 'may lose' and 'may gain' underlie the label.

Common pitfalls

• Reading 'gamble' as 'doomed' or 'guaranteed' — both contradict the semantics of risk.

Final Answer
Both I and II are implicit.
