Stock Market Technical Analysis – Tech It Easy (thru May 18, 2012)

Stock market technical analysis is all you need to know, complete hogwash or somewhere in between.  It depends on who you ask.  If you find it interesting, you’ll probably like reading this weekly feature.

This is my standard intro to stock market technical analysis – you can skip down to the table (or click “continue reading”) if you read this feature regularly:

Many people who trade in the markets believe that there are patterns that can generally lead to profitable trades.  By analyzing stock charts that show the change in price along with the volume (how many shares were traded), “technical analysts” believe they have an edge and can time their trades profitably.  There is significant controversy over this subject, however.  Others say that, unless you have some information that no one else does, basically you can never beat “the market” because everything is already baked into the current price of a stock.

Nevertheless, supporters of stock market technical analysis are everywhere, and the tools for their trade can be found throughout bookstores and the Internet.  I like to follow some websites that do some of the work automatically and provide a snapshot opinion of whether a particular stock is considered “bullish” (going to go up in price), “bearish” (going to go down in price) or “neutral” (stay about the same price).

For simplicity, I’d like to start by showing you a snapshot of what several stock market technical analysis websites suggest about the exchange traded fund (ETF) with the ticker symbol of SPY.  This fund is supposed to go up and down the same as the S&P 500 index does.  And many people consider the S&P 500 index (a measure of the price of the 500 largest companies that trade in the U.S.) to be an accurate gauge of where “the market” stands.

For each of the sources below, where I have a choice, I will use a measure that attempts to predict the future direction of SPY or S&P 500 in the next 3 months.

S&P 500 Technical Analysis Summary

Source: Barchart.com   |   BEARISH   (downgrade)

Quick ‘n Easy

Barchart.com says that SPY is positioned to fall over the next three months.  One of the three signals is bullish, but it’s not a strong signal.  Fortunately, that one bullish signal happens to be the most predictive of the three, but it also happens to be moving toward a more bearish direction.  Thus, the overall analysis is bearish.

Easy Notes: BarChart.com says that SPY is positioned to fall over the next three months.  This is the first non-bullish assessment after 23 consecutive weeks at a “bullish” level.  Two of the three signals are in the “sell” position, and the only that is considered a strong signal (at maximum strength actually and getting more so) is one of those two sell signals.  The one “buy” signal does happen to be the most predictive of the three signals, however.  But it is only average strength and moving toward a bearish direction.

Stock Market Forecast Update

I have updated my Stock Market Forecast page with the latest system I’m testing.  You can read the explanation there in detail.  The quick summary is that I’m doing two models (4-week and 13-week), both using a linear regression model (a statistical way of finding a straight-line relationship between a set of variables and a calculated outcome) that involves four different technical analysis data points.

I graph the forecasts for each model over the coming 4-week or 13-week period, as well as lines that show the overlap between the 95% confidence intervals for each model.  In a sense, I am looking for where both models agree about the direction of the S&P 500.

Lastly, I will issue a weighted combination forecast each week in my update post.  This represents a weighted average between where the two models think the S&P 500 will close this upcoming week.  The weights are based on how sure each model is – that is, using the “standard error” for the regression analysis.

Performance of Last Week’s Forecast

Both models mistakenly predicted that the S&P 500 would rise for the week.  The 13-week model was much closer to the actual closing level (2.67 percent too optimistic versus 6.11 percent for the 4-week model) of the S&P 500 at the end of the week.  The accuracy of each model’s forecast (how close it was to the final S&P 500 level, regardless of the direction being correct) was best, if you can call it that, in the final week.  The actual closing level of the S&P 500 was inside the 95 percent confidence interval for both models but only for the final estimate they made – i.e., just one week in advance.  All in all, it was another miserable performance for both models.

Here’s the basics for the upcoming week’s forecast:

S&P 500 Technical Analysis Summary

Quick ‘n Easy

Barchart.com says that SPY is positioned to rise over the next three months.  Two of the three signals are bullish, but one of those is at its weakest.  The one signal that is neutral is the least predictive of the three but also happens to be moving toward a more bearish direction.  Thus, the overall analysis is only cautiously bullish.

Easy Notes: BarChart.com says that SPY is positioned to rise over the next three months.  This is the 23rd consecutive week with a “bullish” assessment.  For the seventh time in eight weeks, one of the three signals is “hold” again, and it looks to be headed toward a more bearish position.  Fortunately, that signal is the least predictive of the three.  One of the two other signals (both “buy”) is at the weakest possible strength and headed in a bearish direction, while the only strong buy signal is also headed in the wrong direction.  So, this bullish assessment isn’t particularly reassuring as bullish assessments go.

Performance of Last Week’s Forecast

Both models mistakenly predicted that the S&P 500 would rise for the week, and both were off by at least 5.5 percent for the actual predicted value of the S&P 500 at the end of the week.  The accuracy of each model’s forecast (how close it was to the final S&P 500 level, regardless of the direction being correct) was best, if you can call it that, in the final week.  The actual closing level of the S&P 500 was inside the 95 percent confidence interval only for the 4-week model.  All in all, it was a miserable performance for both models.  Basically, neither model was able to foresee the sizable drop that occurred last week.

Performance of Last Week’s Forecast

Both models correctly predicted that the S&P 500 would rise for the week, although the 4-week model was significantly too optimistic.  Still, this was the best week the S&P 500 has had since March.  The accuracy of each model’s forecast (how close it was to the final S&P 500 level, regardless of the direction being correct) was best in the final week.  The actual closing level of the S&P 500 was inside the 95 percent confidence interval for every week for both models.  All in all, I’d say it was a fairly solid performance, particularly for the 13-week model.

Here’s the basics for the upcoming week’s forecast:
