Check off another milestone for Apple Inc. — it's now the most valuable company of all time. The technology behemoth achieved that distinction with the latest jump in its seemingly irrepressible stock price. Apple shares have been on a steady uptick for years, and investors now value the company at $623.5 billion. That surpassed the previous high of $616.3 billion, not adjusted for inflation, notched by rival Microsoft Corp. at the end of the late-1990s dot-com boom.
