There’s been a Market Correction, Should you be Worried?

Should you be Scared of the Dow’s 1700 point drop

On the fifth of February 2018 the Dow Jones Industrial Average saw its largest single day drop in history. This drop coming off a market sell-off at the end of January has caused many investors to call for the start of a bear market. Are these claims well founded, or just good headlines?

Firstly, dollar amounts are likely the worst way to look at market changes as they skew the data. In 1929 the Dow fell from around 300 to 230. A 70 point move means nothing in today’s market environment.…

Turtle traders, part I

About the book

I’m about 1/3 of the way through “The Complete Turtle Trader” by Michael W Covel, and I’m enjoying myself.  His narratives about the people are entertaining, though that’s not why I bought the book.  It does give me color into how technical traders think, though.  It also is nice to hear that simpler is better.  I also like his scientific approach:

  1. Figure out what you are going to do while the market is closed.
  2. Follow the rules while the market is open.  Don’t put new ideas into practice in the heat of the moment.  Follow the rules you’ve made!

When it comes to figuring out what positions you want to add to your portfolio, it can be extremely useful to sort the results of your screen even further. We can do this by using deciles, or breaking up our results into units of 10% as we rank our results based on whatever variable we decide is important.

So How Could you use this?

All you have to do is use our “rank_across” operator.…

Pokémon Go, Nintendo’s Saving Grace or a Desperate Hail Mary?

Pokémon Go, Nintendo’s Saving Grace or a Desperate Hail Mary?

In recent years Nintendo has come on hard times as people have gravitated away from their console systems and towards competitors such as Microsoft or Sony. Since the relative failure of the Wii system they began to lean heavily on their hand held DS systems; however, sales of those too began to suffer as mobile gaming became more of a common place among target audiences.

Breaking the pattern, now Nintendo is taking a true stab at the mobile gaming market with their newest release “Pokémon GO”. It targets people who were children during Gen 1 – millennials.…

The Power of the Short

We all know penny stocks are dangerous to buy. People pump penny stocks, forcing them to rise without reason. This creates a highly unstable environment, and the ONLY thing that is certain is the fall of the stock. So my thought has always been, why participate, and most likely lose, in the pump, when I can far more easily get into the almost guaranteed dump? With this idea in mind I went to work thinking of a basic screener that I could use to capture over-bought penny stocks and simulate what would happen in the event they were purchased, or shorted.…

Matthais Parcha BUS483 Research Report

I'm happy to say that we're encouraging university classrooms to use Equities Lab in their classwork.  Here's an example of some of the work that has resulted.  Notice how well the long/short strategy does…  It's been reprinted, unedited, other than some (partial) attempts to format what used to be a Word Document for WordPress.

Rationale for Approach

General Goals

The overall main goal was to create steady, positive returns while avoiding large draw downs and a high standard deviation. The ideal market neutral strategy would generate a high positive alpha combined with a beta close to zero, indicating there is very little exposure to the market.…
