Quantitative Stock Screener and Backtester

Equities Lab lets you screen, backtest and manage your stocks.  Know why you bought any given stock, and when you should sell it.  Our stock screener finds the stocks you want, using quantitative criteria you set.  Our backtester tells you whether these strategies generate alpha, and the watchlists keep your implementation on track.  You can use our charting tools and vast data to dig into a stock's fundamentals, and understand why it is doing what it is doing.

Serious quantitative investors end up using Excel, one or more software packages, and lots of math. Use our complete financials on 18,000 stocks covering the last 20 years to validate your strategies -- worry free. Our data comes from Morningstar, with macroeconomic data from Quandl, and we cover data from "Accounts Payable" through "Non Current Deferred Assets" to "Write Offs". We also include "Market Cap", Close, Volume, and PE in our hundreds of properties.Check out our data...

Does your trading strategy generate alpha

Fundamental quantitative investment strategies seem to be the answer. But, does your trading strategy blend? More formally, do you make excess returns over the market by following your combination of factors. Validating this requires gigabytes of data, programming expertise and attention to detail -- all of which we have. We use a lookahead bias free, survivorship bias free, point in time dataset. This allows you to see what would have happened had you used your strategy in the past. 

You'll see where your alpha is coming from, and be able to figure out why. Then, you’ll want to tweak it. Then you’ll want to validate that it still works. Change the rebalance period, so you trade monthly, instead of once a quarter, and see it still work. Then try once every two weeks, or midway through each month. Add stop losses, minimum holding periods, or more. You can't exactly backtest real life in Equities Lab, but you can come close. You can see how your strategy did, what it bought, how each position did, and more. Learn more about our backtests...

Express yourself

The Piotroski score expressed a formula in Equities Lab

The Piotroski score expressed as a formula in Equities Lab

Structure your formulas and ideas any way you want. You can test almost any financial anomaly with Equities Lab and see if it generates excess return. We can easily express any of the Fama French factors, see how Quality Minus Junk works, or create and validate your own anomaly.  You get auto-completion, a helpful field and operator reference, and built-in help every step of the way.  For instance, people like to use the Piotroski score to filter stocks.  Piotroski score is a nine point checklist, and a good Piotroski stock would have to match seven of these nine conditions.  Checking this in Equities Lab is easy to do: it takes ten statements -- nine for the condition, and one for the count and comparison. Similarly, finding the stocks that are the second cheapest 10% of some valuation metric is easy.  If you want to filter companies before you rank, and you want to collate by industry or other segment, you just do it. It is literally easier to do than to describe.  Here are the ten statements (we just took a screen grab of our built in formula). Learn More About the Editor...

Big Data Analytics applied to the stock market

Investing in the stock market requires big data, which we have.  We can summarize the state of the entire market in a few clear lines, in a few seconds.  We can focus in on a sub sector, or a slice based on company size, or analyze one of the P/E quintiles in more detail.   If you want to know whether highly leveraged companies are overvalued versus their historical average, or whether airlines are outperforming small cap technology, you can see it on a handy chart. See this data crunching in action....

Think deep

We give you access to information buried in the books of thousands of companies. For example, you can test the changing inventory levels and accounts receivable of all companies over 20 years using our Morningstar data set. We have the companies that trade today, as well as the ones that are but a distant memory. You can take these comparisons and rank across their peers in their sector. Then you can see how this ranking changes over time, and select the companies that are moving in the right direction.

Great Graphics

It’s one thing to be told that your portfolio got 10% annual performance, and that it had a monthly Sharpe Ratio of 0.13. It’s another to see it in pictures. It’s yet another to be able to interact with these pictures, and get a deep nuanced understanding of the data. We have scatter charts, heat maps, tilt chart, breakdowns, exportable tables, and more.  We even have regular charts.  Better still, you can take these great graphics and tables, and export them to documents, Excel, or the web, so you can make your points more easily.

See what you are doing

Track your portfolios, keep notes, see how you have performed in the past, and slice and dice your winners and losers. This will let you can have more winners and fewer losers. This overview panel shows you all of your managed strategies, along with your suggested sells and buys.  Our tear sheets let you get an overview of any stock by clicking on it, and you can use the breakdown panel to ensure you don't invest too heavily in one sector.  The notes on each stock let you learn from experience, and the buy/sell tracking keeps you on the straight and narrow.We also integrate with Interactive Brokers, Tradier, and TradeKing, to allow you to place trades directly from Equities Lab, and keep track of how those trades are doing.  We'll also tell you when it's time to sell, and buy new stocks.
