Saudi billionaire Prince Alwaleed bin Talal is hanging on to his $314 million of Apple stock, despite the post attack decline across all markets.

One of the world's richest men, bin Talal said he is confident the US economy can withstand the "jitters", reports Forbes.com. His personal fortune stands at $20 billion as of May.

The Prince said he would not sell any of his stock in any company as a result of declining investor confidence. He holds major investments in many companies, including $9.65 billion in Citigroup, $1.1 billion in News Corporation, $932 million in AOL Time Warner, and $300 million in Compaq.
