can a government employee invest in stock market?

As per government civil services rules a government employee cannot speculate or frequently trade in the market but he can invest for long term goal with the help of a broker. however he will have to duly report his gains and earnings. in other words we can say that a government employee can invest for wealth creation goals in long term but can’t trade in the market. Government does this because government officers have access to market sensitive information which gives them an undue advantage over others they can use that info to manipulate the prices to gain profits.
