Part 10. Technical Analysis Flashcards
Technical analysis
A form of security analysis that uses price and volume data often graphically displayed in decision making.
This allows us to see a battle between buyers and sellers, along with subtle clues as to which side may be winning.
Underlying logical of technical analysis:
- Supply and demand determine prices.
- Changes in supply and demand - in price level and volume can cause changes in prices.
- Past price action can be used to anticipate and project potential future prices with charts and other technical tools.
3 main principles in technical analysis:
- The market discounts everything - assumes price already reflects known factors impacting financial instrument.
- Prices move in trends and counter trends - assumes prices follow trends, which move directionally.
- Price action creates certain patterns that tend to reoccur and may be cyclical - due to market psychology.
Beliefs:
- Irrational behaviour drive market volatility as a reaction to greed and/or fear.
- Since trend and patterns repeat themselves they are often identifiable and predictable.
- By studying market technical data, price and volume trends, the technicians seeking to understand investor sentiment and detect any fundamental change transpiring behind the scenes or may shortly transpire.
- If a time lag occurs between market activities and analyst conclusions, technicians ay be ahead of fundamental analysts in their positioning.
- Valuation models cannot be used to derive fundamental intrinsic values.
Market microstructure
This deals with issues of market structure and design, price formation, price discovery, transactions and timing costs, information and disclosure and investor behaviour.
e.g. minimum tick increments, algorithmic execution interfaces.
Aims to establish connections between activity over fast moving ST and properties that emerge over longer time frames.
Technical analysis vs fundamental
- Technicians solely focus on analysing markets and trading of financial instruments, but fundamental is a much wider field, encompassing financial and economic analysis, as well as analysis of societal and political trends.
- Technicians analyse market prices, solely from price and volume data, but fundamentals study a company, incorporate external market data, an use analysis to predict security price movements.
- Technician has more concrete data, but fundamentals use numerous estimates and assumptions from a financial statement combined to use various line items.
- T seek to project level at which financial instruments will trad, but F seek to predict where it should trade.
Interpreting technical analysis
- Best and most easily applied to liquid and deep markets.
- Can be applied to different asset classes such as equities etc.
- Impacted by market participation, i.e. retail investors tend to have less in depth info, being more momentum-centric than institutional investors.
- Institutional investors have enough float/liquidity in given stock to participate in scale.
Backtesting
This is a method of assessing the viability of a trading strategy by showing how the strategy would play out using historical data.
Line charts
x axis = time
y axis = price level
- the most effective tool for analysing price action because they show the closing price of the day, week or month.
- closing price is regarded by traders and investors as the most important data point, as it reflects the final decision for that periods transactions.
Bar chart
- This has 4 bits of data in each entry, the high and low prices encountered during the time interval, plus opening and closing prices.
- Vertical line connects the high and low prices of the day.
- Cross hatch the the right indicates the closing price.
- Cross hatch to the left indicates the opening price.
- this chart is most useful in ST trading, as spikes on upside and downside forming support and resistance levels can be visibly seen.
Candlestick chart
This provides 4 prices per data point, the opening and closing prices, and high and low prices during the period.
Vertical line (wick/shadow) = this represents the range through which he security price travelled during the time period.
Body of candle is white/clear = if opening price was lower than closing price.
Body of candle is dark = if the opening price was higher than the closing price.
Advantage of candlestick chart over bar chart
- The price fluctuations are much more visible which allows for better analysis.
- The bar chart indicates market volatility by the height of each bar, but candlestick shows the difference between opening and closing prices, and relationship to highs and lows of the day are clearly apparent.
Candlestick chart: doji
- This signifies that after a full day of trading, the positive price influences of buyers, and negative price influence of sellers exactly counteract each other – market under analysis is in balance.
- If occurs at end of long uptrend or downtrend, it signals trend will probably reverse.
Linear scale
There are equal vertical distances on the chart corresponding to equal unit change.
Better suited for shorter term price charts.
Logarithmic scale
This equals vertical distances on the chart that corresponds to equal percentage change.
More appropriate when working on longer time frames – appropriate when data moves through a range of values representing several orders of magnitude.
