How to profit from PEAD (Post Earnings Announcement Drift)
This tendency of stocks to move in direction of earnings surprise is called PEADS.
PEAD (Post Earnings Announcement Drift) is a very well known and extensively studied market anomaly. Ball and Brown first documented the PEAD phenomenon in 1968. Since then hundreds of thousand studies have confirmed their findings across world markets. Stocks that beat earnings substantially and exceed analyst expectations outperform over period.
Everyday during earnings season number of companies surpass earnings expectations or miss earnings. When earnings is announced it is compared to existing expectations.
If the earnings is a major surprise to the market then the stocks reacts immediately to that news. Most of the time the stock with significant earnings surprise will make 40 to 100% move on earnings day itself if it is a small cap with low float. Depending on market conditions these stocks can go in to multi week rally. In uncertain market conditions, they tend to pullback and go sideways or form range and then breakout nearer to next earnings.
There is a cockroach effect in earnings trends. One earnings surprise is typically followed by many more earnings surprises. When you focus on first earnings acceleration there is good chance your stock will have more such earnings. So effort spent in researching stocks during earnings season can pay you off for many quarters. The structural factors which contribute to earnings acceleration do not disappear in one quarter. That is why earnings trends persist and price trends persist.
