  • Positive earnings surprises often have an upwards price drift for weeks following the announcement.
  • This effect is known in academic literature as PEAD (Post-Announcement-Earnings Drift).
  • A simple strategy based on PEAD has a grossed an annualized 35% since 1999.

If you have read any of my articles, you already know that I am a stock screening and historical backtesting enthusiast. After a recent blog post where I wrote about 17 stock screening strategies that beat the market, I received a comment from Seeking Alpha member, John Beresford Tipton, encouraging me to regularly write and update real-time performance and picks.

After giving it some thought, I realized this was an excellent recommendation giving me opportunity to explain and demonstrate various alpha-creating techniques to the Seeking Alpha community while creating a track record they could follow. Thank you, John Tipton, for that suggestion.

I would like to expand on this idea and offer to anyone who reads this article that you can suggest any strategy or model in the comments section below. I will endeavor to write about it, and if there is enough interest in that model, I will regularly post updates here. So please fire away with any ideas you may have.

Blowout Quarterly Earnings Strategy

The first model I want to discuss uses earnings surprises as its main driver. This is not a new concept. It was reported on in 1989 by Bernard and Thomas in a white paper titled, Post-Earnings-Announcement Drift: Delayed Price Response or Risk Premium?, and has been a hotly debated subject ever since. I am not here to argue why this anomaly occurs or to take sides in the 'more risk' or 'slow reaction time' camps.

What I do find is that tiny stocks with little analyst coverage and whopping big earnings surprises have extraordinary returns for at least 4 weeks following the reported earnings blowout.

My Simple Earnings Surprise System

My rules for the Earnings Blowout Strategy is very simple.

  • Market capitalization under 500 million
  • Average daily turnover (price x volume) for the past 20 days more than $50,000
  • 4 weeks or less since earnings announcement
  • At least 100% EPS surprise in the most recent quarter

In a historical backtest starting in January 1999 until December 2016, the gross average annual performance of this simple system is 35.3%.

Of course, you would have to take into consideration brokerage fees and slippage for net returns. I don't include this because so much is dependent on how much capital you are trading, your brokerage and execution skill.

Is Bigger Better?

It is important to note that I do not find significant out-performance for stocks which are larger than $500 million. Earnings surprises in stocks such as Big Lots (BIG), Central Garden & Pet (CENTA), Frontline (FRO), Guidewire Software (GWRE) and Workday (WDAY) have far less little impact if you jump on the bandwagon after the announcement.

I believe that the larger and more liquid and widely-covered a stock is, the more efficient the market is at pricing this in. Well, so much for not stating which side of the argument I fall on.

Recent Large Surprises

So far in 2016, this strategy has returned 95% to date as opposed to an equal-weight S&P 500 total return (RSP) of around 13%, or 10% if you use the cap-weighted S&P 500 SPDR (SPY).

Here are some stocks which have a recent earnings surprise of at least 100%. Remember that our strategy holds no longer than 4 weeks.

  1. Atossa Genetics Inc. (ATOS) - 105% surprise
  2. Bazaarvoice (BV) - 1,498% (kinda bogus figure as the expectation was 0 and they made 2 cents)
  3. Christopher & Banks Corp (CBK) - 800%
  4. Exa Corp (EXA) - 500%
  5. Platinum Group Metals Ltd (PLG) - 586%
  6. Tabula Rasa Healthcare Inc - 216%
  7. Xcerra Crop (XCRA) - 350%

Keep in mind that some of these numbers will look a little wild due to small or even negative earnings numbers in the mix. As always, do your own due diligence.
