It took more than three decades for the clothing designer Michael Kors to reach the pinnacle of the fashion world. But it has taken just 14 months for him to become enormously rich.

Since the initial public offering of Michael Kors Holdings in December 2011, Kors has sold about $700 million worth of the company's stock. His latest sale, of about 3 million shares, or $180 million, came Thursday as part of a large offering by Michael Kors insiders. Even with all the sales, Kors retains a 2.5 percent stake, worth about $300 million not bad for a Fashion Institute of Technology dropout.

The aggressive selling by Kors and his colleagues added to the large volume of share sales by public company executives in recent weeks. As the major stock market indexes trade near their five-year high, corporate insiders are taking advantage of the rally to profit from their holdings.

In the past week alone, executives at 153 companies in the Standard & Poor's 500 stock market index sold shares, with sales outnumbering purchases by 17 to 1, according to research compiled by Pavilion Financial, a Montreal brokerage firm, and Bloomberg. Prominent sales included those by Larry Page, chief executive of Google, who sold about $65 million worth of stock, and Rupert Murdoch, who offloaded about $40 million of News Corp. stock.

John D. Idol, the Michael Kors chairman and chief executive, has also been a big seller of his stock holdings. After a sale Thursday of about 2 million shares, Idol has unloaded more than $400 million in shares owned by him and his family since the IPO. He retains about a 1 percent stake in the company.

But the money raised by Kors and Idol looks modest compared with the stock sales made by Michael Kors' private equity investors, Lawrence S. Stroll and Silas K.F. Chou.

Stroll and Chou run Sportswear Holdings Ltd., which acquired the Michael Kors company in 2003 for about $100 million. Heading into the IPO, Stroll and Chou controlled slightly more than half of the Michael Kors company. On Thursday, they sold about two-thirds of their remaining stake and now own about 6 percent. They have sold roughly $3 billion worth of shares over the past 14 months.
