Performing one time step per day may not be enough to fully capture the randomness of the motion of the market. In practice, these N steps would really represent what the price might be in some shorter period of time $($much less than a whole day$).$

Furthermore, performing a single numerical experiment will not give us a realistic expectation of what the price of the stock might be after a certain amount of time since the stock market with no moving forces consists of random movements.

Run the code snippet above several times $($just do shift$-$enter again and again$).$ What happens to the asset price after N days?
