The shares have underperformed the market this year, and the client has spoken with Jacobs about closing out the position.

Since the stock is thinly traded, Jacobs buys 1,000 Timeco shares in his personal account in order boost the company's share price, with the intent of reversing the trade a few days later. After making the purchase, the share price rises, allowing Jacobs to convince his client to hold on to his Timeco shares. Has Jacobs violated the Standard on market manipulation?
