Broadcom Stock Hits Record of $208.63

The stock of Broadcom Corp. soared $12.13 a share Monday to close at its all-time high of $208.63 amid rumors that the Irvine chip company would split its stock. In midday trading, the stock spiked to $215.25 a share.

Company officials declined to comment on the rumblings of a split, which have been spreading across message boards on the Internet for the last few months. The developer of chips for high-speed data transmissions last split its stock in February. It declined to say whether the subject was brought up in a shareholder meeting held Monday.

Officials said the meeting, which contains routine items such as approval for boosting the number of shares in the company’s employee benefits program, was brief.

Since the beginning of the year, the stock’s value has risen 229%. With Monday’s stock jump, co-founder Henry Samueli’s Broadcom holdings rose to $3.94 billion from $3.7 billion Friday, and co-founder Henry T. Nicholas III’s to $3.92 billion from $3.7 billion Friday.
