70-year old widow provides her life savings of $300,000 (nearly all of her income) to Jingwen a financial planner. Jingwen places 50% of her funds in corporate bonds rated AA or higher, and 50% in a variety of vehicles including penny stocks, options, and commodity futures. After two years, interest rates have fallen, but the total value of the portfolio is $240,000 due to losses and trading expenses of managing the speculative portion of the portfolio. Has the planner (Jingwen) acted ethically? Why? Be brief and clear.
