$Microsoft(MSFT.US) Microsoft has set a record. The largest single-month drop since 2000, and it's down nearly 30% this year. The P/E ratio is also at a historical low of less than 20 times. Even with double-digit revenue and profit growth that beat market expectations. This is what I mentioned in the weekly strategy report: in a market with significant volatility, the test lies in stock-picking ability, not every decline is a buying opportunity.
