Stock Trends statistical analysis

Stock Trends is distinctive - and perhaps, most effective - because it is simple. However, we are working on publishing statistical analysis of our data so that investors can execute trades with a defined positive expectation. We're keeping it simple, but the analysis will be more powerful.

Investors are always looking for an edge. More specifically, they are looking for ways to beat the market. Even if the investment climate secured tidy 8 per cent annual returns – a fairy tale now – many investors would still strive to satiate a greater appetite than the market’s benchmark performance. It is human nature to want more, to believe that we can have more. And when investors get word of some having more – of achieving much superior returns than the market inherently provides – well, their drive to share in the bounty is fast and furious. The drive to be smarter- to be better - brings forth a plethora of financial models, portfolio management practices, and trading strategies.  Stock Trends, like many advisory services, exists because of this demand.

Even though the weekly analysis that Stock Trends generates is - by design - simple, it offers plenty of statistical feed for those demanding quantifiable evidence of its effectiveness in creating positive expectations for every trade. Positive expectation means that the investor has some measure of probability that a given trade will succeed. Without positive expectations of success the investor is better off throwing darts – maybe even better off paying an investment manager to lose money. At least with managed money you can always blame your advisor when things go wrong!

How can we create a trading strategy that has positive expectations? How do we measure these probabilities? These are the essential questions. Every investor should already know – through wisdom or hard-earned experience – that one cannot expect to be ‘right’ all the time. No matter how you go about it, stock picking with high degrees of success is difficult. Yes, many trades can jump off the charts and reward handsomely; but many others will defy all your best judgment. Successful traders know that in order to make their trading records profitable over long periods, sound money management principles need to be the foundation of a trading plan. Questions of how much to trade, and when to sell are as important as what to buy. The stock picker is just one aspect of the trader.
 
Nevertheless, finding stocks with high, or acceptably high, probability of success is important. Market-timing approaches will focus on selecting stocks with evidence of a positive correlation between current market indicators versus the empirical record of market indicators already exhibited. Stock Trends offers a wonderful opportunity to examine the statistical record of the weekly observations of the indicator variables published here. By running statistical probability analysis we will be able to more accurately represent the meaningfulness of the Stock Trends analysis. Every Stock Trends Report should also answer the question: what does this mean?
 
By looking back at share price performance of grouped observations – that is, stocks/ETFs that have exhibited similar Stock Trends indicators, price, and volume – we can make some representation of the probability of the share price advancing, and to what degree we might expect it to advance. The simple Stock Trends indicators provide us with a laboratory for understanding the statistical significance of the variables describing each issue reported on every week. It is not enough to say - in the way technical analysis purports in its base premise- that prices trend and these trend patterns tend to repeat themselves. We should be able to quantify these patterns. We should be able to provide a confidence level for achieving some mean (statistical average) performance level and quantify the variability of the statistic.
 
If that sounds Greek to you (or Swahili, if you are Greek), don’t leave quite yet. All you really want to know is: “What actions do I take?” Buy, sell, hold. Right now the Stock Trends analysis - presented either in tabular form in weekly reports, or individual records found in the Stock Trends Reports – provides a framework for market-timing trading. That is represented below.

However, we are now working toward building new dashboard tabs in the Stock Trends Reports that will present statistical probabilities of positive expectations. For instance, what is the probability of a positive gain in the upcoming 4-week period? In the next 13-weeks? Past performance does not guarantee future results, but we can give a statistical confidence level in matching the mean (average) results of the historical datasets.
 
Some of these models can be built off of random resampled observations. Certainly, empirical results can also be compared to random results. In fact, it is important when measuring performance of a given data set to provide a benchmark against random results. Correlation of performance results to the Stock Trends indicators must be measured against the returns on random picks. No matter how rigorous the model, we have to show the analysis beats the monkey.
 
We will be talking about this statistical work more going forward. Let’s hope you find it meaningful in your own investment approach. In the meantime, Stock Trends will continue to do what it has for almost two decades: give investors consistent trend and momentum reporting every week.

  • I am just writing to tell you of my appreciation of your service! It makes so much sense to me. You seem to be an oasis of stability and sensibility in a stockmarket jungle.

    Adrian S., Subscriber

  • I am fascinated with your service and methodology - it is very impressive. [...] Over the years I have concluded that there are many ways to approach stock investing, but once one has chosen a path, one is better off sticking to it.

    Bob E., Subscriber

  • Hence, anyone who had followed the "Stock Trends" line should have sold their Bre-X shares and, with the windfall, paid for a lifetime subscription to The Globe and Mail and more. Talk about return on investment!

    Muni P., Subscriber

  • I've followed a number of Stock Trends picks, and the methodology is solid.

    Doug B., Subscriber

  • You have created and maintained an amazing, highly educational program and I am grateful for your part in getting our retirement funds to the good place they are.

    Karin M., Subscriber
  • An admitted cynic, it's obviously very high praise when he says he likes StockTrends because of its "simplicity, utility, openness, [and] honesty," and in addition to having "no hidden agenda" is "understandably documented [and] historically verifiable." And, he adds, "It lets me see a lot of things without doing a lot of work." Globe and Mail

    Paul W., Subscriber

  • I want to thank you for posting such an excellent guide to technical analysis on the web. You have provided a great service to all of us novice investors.

    Michael C., Stock Trends user
  • Stock Trends analysis quantifies nicely the movement of individual stocks. I’ve found that if the technicals are out of synch with fundamental analysis, it is a wake-up call to make a decision. The Stock Trends Bull/Bear Ratio is useful in identifying major market bottoms and tops. It has always presented a good buying or selling opportunity.

    Charles G., Subscriber
  • Just thought I'd call to thank you, Skot. Stock Trends Weekly Reporter helped pay for my daughter's education!

    Peter H., Subscriber

  • Your report is an impressive, excellent tool and I have recommmended it to friends.

    Colin E., Subscriber

  • Stock Trends information is part of the base information I review before making a trade.

    Subscriber
  • Thank you for your excellent work and kind approach to your customers.

    Odette C., Subscriber

  • I am something of a momentum investor. I find Stock Trends useful as I can look at my portfolio as a “watch list” and quickly see where trends are declining in strength or reversing, so it is particularly useful as a tool in portfolio management regarding sales.

    William C., Subscriber
  • I use Stock Trends to help direct my stock picks. Also, following the advice of Stock Trends I have religiously used stop-loss orders and have avoided hanging on to losing stocks for emotional reasons.

    John B., Subscriber
  • There is a lot to be gained from comparing trends of how individual stocks are doing within a sector, as well as how the sector is performing relative to the broad market.

    Dudley R., Subscriber

  • Stock Trends Weekly Reporter is an easy way to pick up equities that represent an upward trend.

    Subscriber
  • I very much like the systematic approach to analyzing stock data, it fits my approach.

    Subscriber
  • I've followed your recommendations since reading your columns in the Globe & Mail, and finding they published Stock Trends arrows in their financial listings. I do find them a guide to the general market and what I should be avoiding for declining chart trends.
    Has probably saved me the subscription by not rushing into hot stocks!

Stock Trends Editorial

  • High-Volume Leaders: A Closer Look at the Heaviest-Traded Stocks
    High-Volume Leaders: A Closer Look at the Heaviest-Traded Stocks Stock Trends’ Unusually High Volume () indicator flags stocks whose weekly trading volume is at least 200% of their 13-week average. In the October 31 weekly reports, only a small slice of the universe qualifies—making these signals rare and valuable. When high volume coincides with a bullish trend state (or a new Bullish Crossover), it can mark institutional footprints at the start of a multi-week advance.

  • Positioning for Opportunity: Trade Detente and Stock Trends Momentum
    Positioning for Opportunity: Trade Detente and Stock Trends Momentum The easing of tensions between the world’s two largest economies has given markets a fresh narrative. By stepping back from new export restrictions and cutting key tariffs, the United States and China have removed some of the most disruptive threats hanging over global supply chains. For investors, this détente creates a backdrop of relative stability in which powerful price trends can resume and new trend…

  • From Flash Crash to Rotation: The Probability–Payoff Map of a Rebuilding Market
    From Flash Crash to Rotation: The Probability–Payoff Map of a Rebuilding Market The market’s October tremor—an abrupt but short-lived flash crash—has given way to a familiar pattern in the Stock Trends framework: the rapid repair of breadth and the birth of new trends. Where panic once pressed prices indiscriminately, order is returning through a disciplined sequence of new bullish signals, rebuilding sectors, and the subtle reorganization of leadership beneath the surface.

  • Random Portfolios as a Benchmark: A Smarter Yardstick for Performance
    Random Portfolios as a Benchmark: A Smarter Yardstick for Performance Investors often compare performance to market indexes like the S&P 500, but traditional benchmarks have built-in biases. The S&P 500, for example, is heavily skewed toward large-cap stocks and “is not a good benchmark for measuring alpha” – it reflects a size-factor bias rather than pure manager skill. All major indexes systematically tilt toward certain factors (size, sector, value/growth, etc.), meaning they’re not truly passive…
