Stock Trends Slots game!

There is a new Stock Trends learning application installed on the Stock Trends website - a slots game! The Stock Trends Slots game engages users by generating random sets of stocks and matching combinations of their Stock Trends indicators. These matching combinations score points based on the probabilities of the match. Every week a new set of Stock Trends indicators reflect the changing stock market, so the game’s probabilities and rewards change with the distribution of the indicators.

Investors might wonder how a random outcome game applies to the markets. But there are aspects of skill in the game that come with the premium functions subscribers to Stock Trends Weekly Reporter may access. The ability to lock game rows allows users to improve the probabilities of making a match without a corresponding reduction in reward. That means a skillful player who understands the distribution of trend and price momentum indicators in a current market can achieve higher scores.

Each spin of the game creates a random portfolio of five (5) stocks and/or ETFs. This is a useful application of random portfolio generation that also makes for an interesting stock market game. These random portfolios - generated by the Stock Trends Slots game play - can be entered into the Stock Trends Investor Challenge, a weekly stock market competition to see which portfolio has the best return after 4-weeks of actual market activity.

This stock market game helps illustrate how random portfolios perform relative to the market benchmarks. Users have some degree of skills-based intervention in the Stock Trends Investor Challenge as they can either choose to enter their slots game portfolio, or not. The Stock Trends indicators help give guidance on that decision, just as they do for actual stock market analysis.

Give it a try!




Trend profile - SPDR S&P Metals & Mining ETF $XME

Stock prices tend to move in trending patterns. This is a simple idea that may, or may not be supported by evidence. It really depends on how you frame the question and what time frame is presented. That’s because prices also tend to revert to a mean or average price. This interplay of price trend and price reversion is a fundamental dynamic of the market. It’s also the window dressing for evidence of randomness that underpins market price patterns.

It’s easy to not recognize randomness when we focus so much on trend and reversion. A core mechanism for human understanding is our ability to identify patterns and formulate responses to them. Indeed, much of our learning is dependent upon pattern recognition. Why shouldn’t our understanding of the markets be based on the same formulations?

Many successful trading strategies are based on pattern recognition. Whether fundamental or technical in nature, these systems win when the precepts of their approach match what the market is delivering at any particular span of time. Market is trending: systems based on price trend patterns win. Market is reverting: systems based on price reversion patterns win. A truly intelligent trading system would know how to recognize the difference between the two and when to apply either a price trend system or a price reversion system. (Orpheus Risk Management Indices (RMI) is one such intelligent system http://www.orpheusindices.com/)

However, attempts to predict outcomes in a world of true randomness cannot be absolutely defended, by definition, no matter how intelligent. Looking for patterns in randomness brings us to Chaos theory and fractal mathematics, which explores the transitions between order and disorder in deterministic systems dependent of initial conditions.

This is heady and fascinating stuff that has a growing influence on financial markets analysis, but how does a stockpicker fit in all this? It’s no wonder that the era of the stockpicker is quickly transforming into algorithmic and machine learning systems increasingly favoured by capital markets money managers. That’s all well and good for highly capitalized institutional shops, but what about the little guy?

The Stock Trends Inference Model (STIM) is an attempt to reconcile randomness in the market with evidence of price patterns. It is a simple application of statistics to Stock Trends categorical indicators that answers some basic questions about certain trend characteristics. Examples of these questions include: If the price momentum of a stock is relatively high and it has been in a bullish trend for a relatively long period, will the price momentum continue, and for how long? If a price trend has changed from bearish to bullish, what are expectations for price momentum going forward? If a stock breaks out of a bearish trend, what are the probabilities it will it retreat?

All of these questions are asked with the assumption that the answers provided are independent of the present broad market condition. That is, we want to know return expectations regardless of whether the market is in a bull or bear trend. Why? Because we cannot know whether the present trend of the market will persist. If we make an assumption that it will, then our measurement of the expected returns of an individual market (stock, ETF) will be imprecise.

This is important. When we take a measurement of a particular market condition - as represented in the combination of Stock Trends indicators in each weekly Stock Trends Report for individual stocks and ETFs - the observations of similar market conditions will take place across time periods that span the entire population of observations. Each observation occurs in varying broad market trend phases. In this respect, the Stock Trends Inference Model is broad market agnostic.

For that reason, the base measurement of returns is relative to the historical random returns of stocks, which is about 8% annually, and specifically equate to the following expected returns for each of the relevant periods Stock Trends measures: 0% 4-week return, 2.19% 13-week return, and a 6.45% 40-week return. If a trend condition for a particular stock/ETF does not provide statistical evidence that it can beat these base return expectations, then we cannot say anything definitive about its return expectations. However, if there is a deviation from the base return expectations we can say that the current trend characteristics indicate either over-performance or under-performance projections. This is the objective of the Stock Trends Inference Model.

A good starting point for Stock Trends Weekly Reporter subscribers is a weekly review of the STIM Select stocks report. It shows the stocks and ETFs that have the best statistical trend characteristics. The report is ranked by the 13-week return expectations.


The current NYSE STIM Select report, as an example, includes the SPDR S&P Metals & Mining ETF (XME-N).  The Stock Trends Report for XME shows that the ETF is 7-weeks into a Weak Bullish trend; that it is underperforming the S&P 500 index by 12% over the past 13-weeks and underperformed the broad market index last week  (RSI 88 - ). It’s been in a Bullish category for 54-weeks but has been retreating since February.

SPDR S&P Metals & Mining ETF $XME -  Stock Trends Report


The statistical model shows that there have been about 277 observations of stocks and ETFs that have shared these characteristics or have had similar Stock Trends indicator combinations. From this sample we can make inferences about the expected returns of XME over the next 4-week, 13-week, and 40-week periods.

SPDR S&P Metals & Mining ETF $XME - estimated returns STIM


The green sample density plots show the distribution of returns for the three separate periods following the observation. Most generally, these distributions will be centered around the mean random return expected for each period ( 0% 4-week return, 2.19% 13-week return, 6.45% 40-week return). However, certain Stock Trends indicator combinations yield sample distributions that deviate from the expected mean random returns. The sample distribution of returns generated in the XME sample deviate in a positive way.

For the 4-week period 53.8% of returns in the sample are greater than 0%, the expected 4-week return. By employing statistical inference methods to estimate the population mean, we can estimate that the expected (or mean) 4-week return for XME is 1.8%. More importantly, with our assumption of a normal distribution of returns - a defining attribute of randomness - we also can estimate that XME has a 56.5% probability of having a return greater than the expected 4-week return of a randomly selected stock. This in comparison to the 50% probability we would expect from a random stock.

Similarly, the 13-week expected return for XME is 7.2%, with a 60.8% probability of besting the base period expected return of 2.19%, and the 40-week expected return for XME is 21%, with a 64% probability of beating the base period expected return of 6.45%. All better probabilities for beating the returns of a randomly selected stock.

While even a 64% probability is better than a 50% probability implicit in a random selection, it’s still only a 64% probability. There is a 36% probability that it will underperform the expected return of a randomly selected stock. If you know anything about chance, you must know that a 36% chance of being wrong is more than enough to lose your shirt.

However, the Stock Trends Inference Model does tell us that XME is currently in a trend and momentum position that historically has exhibited tendency toward positive returns in the subsequent period. This gives us some confidence in making a directional trade, and can be used as the foundation of a derivatives trade (options) that further improves a trader’s probability of making a profitable trade.

How to Play
Player receives a set of 5 random draws to start the game.
On each draw or play, a random generator fills 5 rows with listings for 5 different stocks, with each record filling the columns in the order of stock symbol, Stock Trends trend indicatorStock Trends volume indicatorStock Trends RSI value, and Stock Trends RSI up/down indicator. Learn more about what these indicators mean in theLearn section of the Stock Trends website.
Each draw the player accumulates points and/or free plays with matching columns and rows, as described in the section below.

At the end of each slots play players may choose to enter a Bonus feature play - the Stock Trends Investor Challenge! Enter your final portfolio of 5 stocks in the rolling 4-week Stock Trends Investor Challenge for a chance to win BONUS awards if your portfolio beats all challengers! Stock Market Investor Challenge winners are awarded every week. (Note: presently we are beta testing the game - no prizes are applied to winners)
Subscribers to Stock Trends Weekly Reporter have the option to lock rows before a spin and improve the odds of making another point scoring match. For instance, if a player has matched two rows, he can select those two rows to be locked in position such that in the following spin only the other three rows are randomly selected. The points payout for matches of additional rows remains the same, but the probability of making those matches improves.
The following rules apply to the locking of rows:
1) once a row match is locked, no points for the locked match are scored on the subsequent spins. That is, there is no double counting of matches when the matches are locked.
2) if the player locks more than two rows, the free spin combinations do not receive free spins. There is a cost to locking more than two rows - the player cannot accumulate additional spins with the free spin matches.


Play to improve your odds and enter your portfolio of stocks 
in the Stock Trends Investor Challenge!

As a subscriber to Stock Trends Weekly Reporter you will have access to additional game features:
