Clueless as always

As always, I have no idea why the market goes up when it does and why it goes down. Was under the impression that companies are reporting strong earnings, recovery is holding up pretty good. Then suddenly S&P-500 drop to 1270 this week. Greece is the problem now ? No idea why AAPL should be trading with forward PE of 11, $320/share. Steve Job's health is a concern there ?Most tech companies I look at have P/E close to or less than 10 !!

MSFT at $24 has a forward P/E of 8.8!! Agreed tablets are the craze now but are PCs going to die in another 8 years ?? MRVL at $13 also has a forward P/E of 8. How should one read this ? Big money does not like tech stocks anymore ? BRCM at $ 31has a forward P/E of 10. I mean someone needs to make these chips and get some money out of it. Should I put all my money into these stocks ? For comparison Nike has a forward P/E of 17, JC.Penny at with forward P/E of 13,so Nike or JC.Penny has better growth prospects than AAPL ? Doubt it.

Will look at these 6 months from now, see which one held up better.
