I'm not really posting this for you, but mostly for the other nice people on the board that you're trying to "get."
1. You would NEVER use a trailing P/E like that to value a high growth stock.
2. A P/E of 10 is EXTREMELY low for a growth company.
3. If growth stocks were valued like you just set forth, then even all big board growth companies would be valued at a FIFTH of what they're actually trading at.
