Three Different Resistance Measures

The S&P 500 has stalled around its 50-day moving average, as was true the other day (see the previous post). Now that a few more days have passed since then, we saw a couple of spinning tops, which indicate indecision, then a large down day (yesterday) followed by a significant up day (today). Today's bullish candlestick was not as large as yesterday's bearish candle, and today the market opened from a higher level than yesterday's close. In OHLC charting, this is referred to as an inside day. Overall, I think it is safe to say that there is no definitive direction for future price change at this time. As I stated in class, at times like this, it is advisable to consult the economic calendar for the remainder of this week and next week, identify the "biggie" releases that will occur, then attempt to determine what each of these will do and how the market will react. Nobody can know this with certainty, so don't be intimidated. Actually, if you listen to the "talking heads" on the financial stations and keep track of what they predict, you'll probably be surprised by how inaccurate these persons are. So, don't be afraid to venture out and try this, you probably won't do any worse than the "talking heads."

Look at the following charts and analyze the most recent candlesticks and think about what they indicate about the battle between bulls and bears. Using these, I will now present three different ways to measure resistance.

#1: Fibonacci Retracement: If we apply a Fibonacci Retracement to the most recent high and low of the daily S&P 500 (see chart, click to enlarge), we see something quite interesting: the recent rally stalled at the 61.8% retracement point. The use of Fibonacci Retracement suggests that after a decline, the first possible point of resistance in a rally is when 38.2% of that rally has been erased (retraced). The next possible resistance point is at 50%, while the last occurs at 61.8% retracement.

#2: 50-day Moving Average: The next charts (click to enlarge) shows that the 50-day moving average acted as support for the S&P 500 since last fall, then became resistance in late January of this year. It is fairly common for prior support to become resistance (and vice versa). Note how the most recent rally failed just at the 50-day moving average. At this point, based on the most recent candlesticks, the direction of future price is still a toss up. A definitive move above the 50-day moving average, especially for a major market index, would be very bullish, and we might have a shot at returning to the previous high. If that were to occur, then the market falls below that level, what technical formation do we have? A double top, which is a reversal pattern. More about establishing a down target later this semester if this possibility occurs.

#3: RSI(9) < 60. In this same chart, look at the RSI in the upper portion. Note how the most recent high coincided with the RSI falling below 60 and remaining there. Just as the S&P is now testing its 50-day moving average, so too is it testing the RSI at 60.Often, an RSI value of 60 is used as resistance for a downtrend, while 40 is used to designate support for an uptrend.

So, what will happen from here? As I stated above, look at the economic calendar, identify the "biggie" numbers that can potentially move the market, and attempt to predict what each of these will do. In doing this, you are actually using economic theory, which states (for our purposes at this point):

      Stock Prices = f(interest rates, expected future profit)

In analyzing the future releases, focus primarily on the macroeconomic implications for profit expectations, since Fed Chair Bernanke indicated again today that the fed funds rate will remain low "for the foreseeable future." That reassurance was a fundamental driver of today's rally which erased most of yesterday's losses.

Surprise Discount Rate Announcment

Yesterday, after the markets closed, the Fed announced that it was raising the discount rate by 25 bp. Here is a story about this. The initial reaction after hours was as expected -- the announcement took everyone by surprise. Before this morning's market open, futures pointed to a down day, although the amount kept shrinking. What all of this points to is uncertainty and indecision as market participants digested all of this and formulated their views of the likely consequences.

Which types of candlestick bars depict this? Forget a candle with a long real body and little in terms of shadows (i.e., tails). Look over the candlesticks I covered the other day in class. One would expect either a doji or a spinning top. What actually occurred for the S&P 500 was a spinning top. Here is a chart of the current data (click to enlarge) as of the Friday close.

The RSI is not yet overbought, so potentially there is room for further upward price movement. Note that the RSI is approximately 60, which is the value that some use to indicate resistance for a time of weak price movement. The most striking thing in this chart is the fact that the $SPX closed above its 50-day MA for the first time since January of this  year. If the market were worried about the impact of the Fed raising the discount rate, would the S&P have closed above its 50-day MA today? No, it would not have. So, today's price action, in spite of signaling indecision in terms of a spinning top, does allow for the possibility that it the S&P will remain above its 50-day MA at least for the very near term. The real question is whether former resistance, in terms of the 50-day MA, will now become support.

How can we arrive at a way to answer this question? Using economic theory, we model stock prices. According to economic theory:

                    Stock Price = f(interest rates, expected profits)

Interest rates pertain to asset substitution possibilities in the short-term (review the stock and bond info in the Supply and Demand notes) and product demand in the medium term. Were yesterday's surprise discount rate announcement taken to indicate that Fed tightening was about to begin, not only would the market have failed to clear the 50-day MA today, there would likely have been a noticeable upper shadow (tail) as well. Also, there was a CPI data report today that signaled benign inflation, which signals that interest rates should not rise much.  So, the primary factor to focus on is profit expectations. For extra credit, due at the beginning of class on Tuesday, plot the relative strength of the S&P 500 (a measure of stocks) compared to TLT, a measure of longer-term bond prices using as a chart type a solid line with weekly data. In a short word document, include the chart with annotations from StockCharts.com (not hand written) and a very short discussion of what the relative strength of stocks vs bonds is showing us about expectations for future economic activity (and therefore profits). Feel free to consult John Murphy's text about this.

When you get a chance, you should read two excellent columns on technical analysis by Michael Kahn in Barron's Online. I strongly suggest that you save these and others throughout this semester (and beyond). The first of these, written in early February, talks about the market correction. Follow his reading of candlestick charts and overall analysis. The second, from this past week, analyzes the question of whether the market will be fighting back and trend up.

Which Way Will the Market Go?

The recent rally has taken a pause at best, and perhaps the recent rally has run its course. While the market has declined for the past two days, today's decline was much larger than Monday, as the S&P fell by almost 20 points back to 815.6. How can we gauge whether this is the end of a rally or merely a pause in an uptrend?

Technical indicators are helpful for this. The following chart (click to enlarge) is the daily S&P performance over the past six months. There are two conflicting signals in this chart. First, note the performance of the RSI. While the S&P has recently risen sharply, that momentum was not confirmed by the RSI (see the lines in the chart). Recall, this is a bearish divergence. But if we work with moving averages, we get a buy signal. In the chart I have added the 20-day and 50-day moving averages. Notice that in the past few days, the 20-day has crossed above the 50-day moving average. This could potentially be considered a buy signal (recall: this is related to the average-marginal relationship we discussed earlier in the semester).

So, which indicator should we rely on? Since moving averages are lagging indicators and a bearish divergence of the RSI is a leading indicator, I would tend to go with the RSI's "signal." But that is still no guarantee that the rally is over -- it merely indicates a short-term pullback is in store which we are now witnessing.

In a situation such as this, you should look at weekly data for whatever information it contains, since weekly data does not contain as much "noise" as does daily price data. The chart below shows weekly S&P data (click to enlarge). I have added the 13-week moving average since this corresponds to a quarter. Note how well this fits the price data.

The weekly RSI shows very different momentum information than does the daily chart. Note the weekly RSI is far from overbought, and there is no bearish divergence. Actually, the RSI has failed for some time to move beyond 50, which would have indicated movement to more bull-market-type momentum.

In this situation, I recommend that you view an RSI value of 50 as resistance for the S&P's price movement. So, based on the weekly RSI, this rally failed at (RSI) resistance. I would only place bets on upward continuation when (and if) the RSI is able to sustain a break above 50. Were this to happen, daily data would clearly have to show an end to the recent pullback.

What's Next for the S&P 500?

The S&P 500 fell all the way to 700 today, which is support going all the way back to 1997. Clearly, financial sector problems, most notably the ongoing problems with AIG (where was Rick Sentelli's rage about the government's action today??), and HSBC, the largest European bank curtailing lending in the US, hurt markets in general.

In order to find the next support levels, go to StockCharts.com, switch to Weekly data, and to make things visible, enter a specific time period. I chose 1996 - 1997 to see things without too many small OHLC bars. In order to find the exact LOW for support, in Annotations, change the Info Mode of the Cursor (far button on top right of Annotation screen). Click two times until it gives the date and specific values for Open, Close, High, and Low when you move to a bar.

I did this and found the next two support levels for the S&P 500 (note: this is depressing, viewer discretion is advised), which is given on the following chart (click to enlarge). Next stop is 644, which is a pretty significant drop from today's level. After that, the next support takes us almost to 600 (at 606).

To determine whether we will likely hit either of these support levels, once again use economic analysis. The primary determinants of stock price at present are proft expectations and the perceived safety of the financial system.

Considering just these factors, we go 0 for 2, so the likelihood of reaching 644 suddenly becomes very significant. But at times like this, don't forget the psychology of markets.

A few weeks ago, many of the "talking heads" were saying it was time to get back into the market. Recall, my advice at that time was to get out quickly if you had money invested. Now, there is almost total resignation that a sharp drop is inevitable. Being a contrarian, I see the potential basis for a short-term bear market rally. So, barring any more horrible news (remember we have the employment report Friday), we might move up shortly.

The initial claims news on Thursday will probably bring more downward price pressure so it is not inconceivable that after a very bad employment report on Friday, we have an initial downdraft followed by a short-term rally. Think about it for a while: if a rally were to occur, when would most people be fooled? Answer: Friday after the employment report. This is only one possibility. Let's see how things actually play out for the rest of this week.
