JPMorgan Chase & Co. saw top executives unloading significant amounts of stock this week, with a total of about $169 million being divested. Chairman and CEO Jamie Dimon led the sales, making his first-ever sale of $150 million in stock at a price of $182.73 per share. Co-CEO for the commercial and investment bank Troy Rohrbaugh sold $13.7 million in holdings, representing around 31% of his stock in the bank.

The sales were executed through trading plans known as 10b5-1 plans, which allow insiders to sell stock at predetermined prices and times. These plans provide a safe harbor defense against potential insider trading allegations.

Dimon's sale of $150 million came on a day when JPMorgan's stock surpassed $182 for the first time. Since he became CEO in 2005 when the stock was trading at about $40, Dimon still holds 7.7 million shares and has a plan in place to sell an additional 178,000 shares before August.

Other high-ranking leaders at the bank also trimmed their holdings this month. Chief risk officer Ashley Bacon sold shares worth $603,000; CEO of the asset and wealth management group Mary Erdoes sold $862,000; consumer and community banking CEO Marianne Lake sold $798,000; commercial banking CEO Douglas Petno sold $585,000; co-CEO of commercial and investment bank Jennifer Piepszak sold $295,000; and vice chairman Peter Scher sold $324,000.

JPMorgan made it known in October that Dimon and his family were commencing the sale of a portion of their stockholdings for financial diversification and tax planning purposes. Dimon still holds about 8.6 million shares, with a requirement to maintain a minimum holding of 1 million shares or $75 million in stock.

JPMorgan did not provide any comment regarding the stock sales when reached for a response.
