I have not seen any purchases this year reported for ACE's CEO. In contrast, the CEO of HCC has purchased significantly this year, including 9/14/09. HCC's CEO is John Molbeck, Jr.

How well have Mr. Molbeck's past purchases done?

Consider his purchase 2/21/08. I used adjusted share price closing figures provided by Yahoo Finance (adjusted for dividends paid since 2/21) and 9/18/09 closing prices: Here are comparisons:
HCC's stock since 2/21/08: up 15.50%
SPY since 2/21/08: down 17.78%
VTSMX (proxy for entire U.S. stock market) since 2/21/08: down 15.74%.

Consider Mr. Molbeck's 3/14/08 purchase.
HCC's stock since approximate weighted average of Mr. Molbeck's purchase prices on 3/14/08: up 25.23%
SPY since 3/14/08: down 14.19%
VTSMX since 3/14/08: down 12.20%.

ACE's CEO, according to Yahoo Finance, hasn't bought any ACE stock since before June 2008. He has, however, sold ACE stock many times.

If you profit from investing in HCC, please consider sharing some profits with charity. Best wishes,
