Yahoo Maintains History Of Favoring Short Plays Off Evening Earnings

| About: Yahoo! Inc. (YHOO)

Yahoo (NASDAQ:YHOO) is one for shorts to watch tonight as its post-earnings downside follow-through is the more established pattern in our database.

YHOO favors a widening pattern over the past three years, extending its post-earnings share move in the next day's regular session in eight of the latest 10 quarters. The longer-term trend now just favors widening, with 14 narrowing moves between the sessions and 19 wider next-day moves after evening earnings releases. One of the most recent quarters saw YHOO shares decline in the after-hours and hold that same decline the next day.

Looking deeper into YHOO's performance data, the stock has seen an after-hours decline in 14 of the 34 earnings-driven after-hours moves we've tracked, and nine times, or 64% of the time, followed that trade with a more-aggressive decline in the next day's regular session.

On the plus side, YHOO is evenly mixed. YHOO has recorded an earnings-driven evening gain in 20 of the 34 quarters we've tracked. It has widened that gain in next-day regular session 10 times, 50% of the time.

Yahoo! is due with its Q4 results after the bell tonight, and analysts polled by Capital IQ are expecting the company to report a profit of $0.28 per share on revenue of $1.214 billion.
