$yhoo requires

Yahoo needs revenue growth for its core business to appreciate in value.

Above $1.2B would be nice to show yr-yr growth. With solid revenue growth, core biz will increase from its current $10B valuation. 

Technically, a nice bullish development with yhoo seeing higher lows. Hopefully it holds.

Ultimately, its the revenue growth. Yahoo sees revenue growth, and the stock smashes through the 40-41 resistance.
