Teach me Technical Analysis!!!

Welcome to StockJock-e's Technical Analysis 101. Have a seat and pay attention, there will be a quiz at the end.

So what is technical analysis (TA)? Simply put TA is the use of charts to identify patterns and predict future activity.

Many different factors effect the price of a stock, anything from weather, inventory, fed interest rate hikes, inflation, sales and so forth. Stocks go up and down and there is little we can do to predict exactly how a stock will react tomorrow. What we can do however is look at what a stock has done in the past, and from that, gauge an approximation of how it should act in the future.

Let us begin with Lesson #1: Support and Resistance

Step one: Looking at a stock chart.

The first thing you want to do is change your chart from a line chart to a bar chart. Lines are nice, but they dont give us enough information about what a stock did intraday. A bar chart shows us the open, the daily move and the close (candlesticks also do this, but we will get to those later).

Now that you have a bar chart, lets do the most basic of all analysis, lets look for support and resistance levels.

Finding support: Starting from the left in Jan 2005, (first blue arrow), you can see that INTC hit the $22 level, then rallied. In April the stock dropped and hit $22, the rallied again. It seems that $22 is a nice support level. Investors are basically thinking "Hmm, I like INTC and would buy it if it hit $22..." and so they do. If we connect those two support levels and extend the line to the right, it shows us a nice long term support level.

Finding resistance: After that first support was found, the stock rallied, but then stalled at $25.50 in March. You can see that in May, the stock blasted right through that resistance level. Note that support and resistance levels do not have to be horizontal, in fact they can be almost any angle. INTC hit $28 in June, and pulled back, that is another resistance point. By connecting the March and June peaks, then extending the resistance level outward, we find that the next resistance point in July was predicted correctly! Later in November we can see that the old $25.50 resistance stalled the rally, but as soon as it broke through, it moved quickly.

Think of support and resistance levels as jello like barrier, sometimes a stock will bounce off them, other times it will cut through.

Stay tuned for Lesson #2 - Moving Averages

StockJock-e · Dec 2nd, 2005, 03:00 PM

Perhaps the most basic of all indicators is the moving average. It is exactly what it sounds like. If your wife spends $100 today, and $110 tomorrow. Her average spending is $105.

Stocks move every day, so if GE (General Electric) closed at $30 yesterday, then at $30.50 today, the average over the past two days is $30.25.

Now lets stretch this out over say... 200 days, we would get a line showing us the average closing price over that time period.

I did not randomly pick 200 days, the 200dma (day moving average) is actually one of the most commonly used indicators. Even those traders or investors who have no clue about technical indicators would know about the 200dma. It is basically the trend line that if a stock is above it, it is doing good, if it is below it, the stock is doing bad. This is obviously an extremely generalized point of view, but it gives us a general frame of reference.

The 200dma is best used with major indices and blue chips, not small or mid cap stocks.

Let us take a look at the 200dma as applied to GE:NYSE. As long as the stock is above the 200dma, it is considered to be in a healthy uptrend. A strong move below the 200dma would indicate some volatility, and if the stock stays below the 200dma for an extended period of time, it is an indication of continued weakness.

The trend of the 200dma itself is important. If the 200dma is uptrending, that tells us the underlying security is in a strong long term uptrend. If the 200dma is downtrending, then the opposite. A stock will often move above and below the 200dma, but as long as it is in an uptrend, its ok.

Next lesson - short term and multiple moving averages

StockJock-e · Dec 2nd, 2005, 03:22 PM

If you want to know the long term trends, a 200dma is fine. But what about shorter term moves?

The same concept applies to short term moving averages. Daytraders will use moving averages based on 14dma or even 5dma for general trends, they even get down to 5min and 1min moving averages, but we are not daytrading here.

Let us focus on long term and mid term trends for now.

Instead of a 200dma, lets use a 100dma and also a 50dma. An interesting thing happens when you put two different time frames together, you get two lines that move around each other.

The blue line is a 100dma, you can see how it showing the general trend of the stock. The brown line is a shorter term 50dma, it is more volatile as it more closely follows the actual day to day moves (averaged over 50 days).

Here comes the fun part: See how the 50dma moved above the 100dma Jan 04 (first blue arrow). This indicates to us that the short term trend was extremely stronger to the upside than the longer term 100 day trend. As you can see, the stock did indeed hit some nice highs. You will also note the opposite (red arrow) when the 50dma fell below the 100dma.

Look at July 04, see how the 50dma once again moved above the 100dma? I good indication of short term strength kicking in. GE went from $32 to $37 over the following months. Now look how the trend changed when the 50dma fell below the 100dma in July 05, this indicator told us that weakness is kicking in and GE subsequently dropped from $35 to $33.

Next lesson - combining what we have learned so far.

Believe it or not, after just these three simply lessons you already have the tools for basic technical analysis... very basic though.

Using the same chart of GE, all I am going to do now is identify a recent support level:

As you can see, in the early part of 2005, the $35 area was strong support. We also see some overhead resistance that stopped the rally in May 2005. Now watch how this signal works out, we see the stock break below $35, next we see the 50dma cross under the 100dma. What followed was a continued drop to $33. If you were a trader, you would have exited the stock at $35 and saved yourself that drop.

Not indicated on that chart is that the $33 area is a support level. Can you see why?

You could have used $33 as a re-entry into the stock.

Chart patterns will by far be your most reliable friend when it comes to trading when combined with other indicators.

Since you are already familiar with support and resistance lines, you will find that chart patterns are a simple extension of that concept.

StockJock-e · Dec 9th, 2005, 12:21 PM

Do not be scared! This is really not that bad!

All I am going to do in lesson 5 is introduce you to two friends of mine, they are basic oscillating indicators, one is called RSI (Relative Strength Index) and the other is MACD (Moving Averge Convergance Divergance).

I have put RSI at the top of the chart, MACD is at the bottom.

RSI

The calculation for RSI is 100-(100/ 1+(U/D)) where U=avg upward price change and D=avg downward price change.

RSI is a oscillator that ranges between 0 and 100. The standard time period that you will find it set at is usually 14 days. Traders will often change this 14d period to make it suit their style of trading. Shorter term for daytrades, longer term (21-50days) for longer term trading.

Simply put, an RSI reading over 70 indicates an overbought situation, below 30 is an oversold situation. Some traders use the peak RSI as a buy or sell signal, others wait for a cross over back below or above the 70 or 30 level to indicate a buy or sell.

This indicator shows you the 'internal strength' of a security. There is also an important divergance signal RSI gives us, which I will cover in a later lesson.

Take a look at this chart. The green arrow shows the RSI touching 30, thats a buy signal. The red arrows show sell signals. You will also note that head n shoulders pattern, combined with the RSI gave a nice sell signal.

MACD

MACD is a momentum indicator that shows the relationship between two moving averages., it is best used in wide swinging trading. MACD is uses crossovers, overbought/oversold conditions, and divergences.

Using the same concept from our moving averages tutorial, when one line crosses above the other, note how the red line crosses the black like at the first green arrow, thats a buy signal. The opposite is true at the red signal.

Important note: No technical indicator is 100% correct. As you become more advanced, you will pick out and combine indicators which suit your trading style.

Important note #2: These are the basics of these indicators, things get increasingly complexed the more you get into it.

I will not open this thread up to discussion before we head further into the deep and mysterious world of technical analysis.
