Apple was the outlier Monday. On a day in which the Dow lost nearly 370 points (having plunged 800 points in midday trading), Apple’s shares actually ended up in positive territory, closing at $98.14, up 1.1%.

But to see that as good news you would have to ignore the fact that at one point Monday Apple was trading for $87.24 a share — off nearly 60% from its December 2007 high of $202.96.

Apple closed down nearly 9 points (9.5%) Tuesday, while the Dow fell more than 508 points (5.11%).

To get a feel for how Apple is really faring, you can compare its performance with what CNBC’s Jim Cramer calls the four horsemen of technology: Apple (AAPL), Research in Motion (RIMM), Google (GOOG) and Amazon (AMZN).

As it turns out, the biggest loser over the past two weeks has been RIM, down 38.5% over the past 10 trading days — and off nearly 65% from its 12-month high.

The best performer of the four: Amazon, off only 9% for the fortnight, and within 40% of its 12-month high.

But Amazon’s price-to-earnings ratio is a dizzying 47, while Apple is now hovering around 20. That’s still above the market average, as Henry Blodget points out in Silicon Alley Insider, “but low for a stock with this wide and passionate a following and a still-solid growth story.”

Here’s a snapshot of the past two weeks of trading, taken before the markets opened on Tuesday:
