Concept:The demand for money to take advantage of future investment opportunities is the speculative motive.
Explanation:When Mr Wale borrows money specifically to invest, he is holding cash to be ready to buy assets when prices are favourable.
This is not for daily expenses, so it is not the transactionary motive.
It is not for unexpected emergencies, so it is not the precautionary motive.
The speculative motive refers to holding money to exploit expected changes in asset prices or interest rates.
Therefore, the demand for money for investment purposes is purely speculative.
