Shares in Apple have reached another record high, continuing their meteoric rise.
Shares of the iPad and iPhone maker eclipsed the $US600 barrier for the first time during trading on Thursday, less than a month after topping the $US500 mark for the first time.
Last month, Apple became only the sixth company in US history to top $500 billion in market capitalization, a significant move for a company whose stock traded at $10 dollars about a decade ago.
Apple makes up about 18.5% of the Nasdaq.
