AST Stock Sold: Two of AST’s founders are selling a small chunk of their holdings in the Irvine personal computer company.

Thomas C. Yuen, AST’s co-chairman and chief operating officer, recently sold 10,000 shares of the company’s stock at $27 a share for a total of $270,000. Yuen still owns 1,669,536 shares of stock.

Safi U. Qureshey, co-chairman and chief executive, filed to sell 20,000 shares of AST stock at an unspecified price on Dec. 7. He still owns 1,931,336 shares.

Joel Don, an AST spokesman, said the sales were routine actions in which company officers exercised their rights under a stock option plan.

AST stock has risen sharply over the past several months. It closed Monday at $26.50, off 87.5 cents a share, in over-the-counter trading.
