Uncle Scrooge's money bin just went from 99 percent full to 98 percent full.
Seriously, read how these stories are spun first. "May face first profit drop in decades." In other words, they will either make less profit than the year before or it may refer to profit not increasing as much.
Either way, the company is still making a ton of profits.
You'll see the same stuff with market share. Apple pretty much had the tablet market for a year. Therefore, any competitors coming in will probably eat into it. A better indicator of the company is whether it's selling more than it did last year and what the profit margin is. If Amazon comes in with a $199 Kindle Fire at low markup and basically taps into a new market but Apple continues to sell more and more iPads, then everybody is winning.
I have also been amused at people acting like the sky is falling with Apple's stock "dropping" to $500. When I bought a few shares of Home Depot stock in 2003, I really wanted to buy Apple but I couldn't afford much. It was about $80 at the time. Again, poor Apple.
