Apple’s and Google’s Stock Prices Are Mirror Images

While Apple’s stock declines, Google’s stock keeps zooming the other way.

If you go back six months, changes in the two companies’ share prices seem to be almost in lockstep, but heading in opposite directions. Overall, Google is up 20.6 percent, while Apple is down 37.8 percent.

As of today, at a market cap of $400 billion, Apple is no longer the most valuable company in the world. Google, meanwhile, hit an all-time high of $822.84, closing the day at $821.50 for a gain of 1.9 percent.

P.S. Explaining stock fluctuations over months-long periods is a messy game, so let’s not go there, but there was a nice bit of discussion over the weekend about open vs. closed — and to some extent Google vs. Apple — here, here and here.
