What is technical analysis?

Technical analysis is a method that uses price data and charts to decipher market dynamics and predict market movements. This approach stems from an investment philosophy distinctly different from that of fundamental analysis, yet in practice, they are not entirely exclusive. Technical analysis is widely prevalent in financial markets, primarily as a tool for market timing. With the advent of machine learning and artificial intelligence revitalising the industry, traditional candlesticks are being infused with new potential.

Technical analysis has a long history in the investment world, dating back at least to the 18th century when the Japanese rice merchant Honma Munehisa introduced the candlestick chart. In general, technical analysts try to study patterns in past price and volume data to understand the supply and demand dynamics of the underlying asset, with the aim of predicting future price developments and making profitable investment decisions. Depending on the implementation, investors may rely directly on price charts, or transform information from the charts into numerical signals and apply heuristic rules to formulate trading strategies.

Technical analysis vs. fundamental analysis: Astrology vs. astronomy?

In the investment world, there is a saying that sometimes compares technical analysis to fundamental analysis, much as astrology is compared to astronomy. This analogy may stem from the fact that fundamental analysis relies on a thorough analysis of the economic fundamentals of the underlying asset to make investment decisions, which seems to offer more substantial merits. Fundamental analysis offers intuitive explanations of the drivers of asset prices, a philosophy that dates back to the renowned value investing guru Benjamin Graham in his book 'Security Analysis' (1934)[1].

The differences really lie in the logic of the investment philosophy and the beliefs or assumptions about the market. Ultimately, if we consider the task of predicting asset returns as a statistical exercise, the major distinctions lie in the data used and the predictive models employed. Fundamental analysts focus on economic factors, including both the macroeconomic environment and the micro characteristics of the underlying assets. Conversely, technical analysts assume that market prices aggregate all relevant information, rendering other data redundant. However, these two approaches should be seen as complementary rather than mutually exclusive, especially when considering the frequency of data availability and its implications for prediction horizons. As Menkhoff and Taylor (2007)[2] point out in their review of technical analysis in foreign exchange markets, technical analysis could be used to capture non-fundamental price drivers, which are more significant in the short run.

Trend following and mean reversion: Why would they work from a theoretical point of view?

Trend following and mean reversion are two groups of technical strategies that are widely used in practice. Trend following strategies attempt to identify the current market trend and invest in the same direction until the trend ceases. Common signals used in trend following include moving average crossovers and time series momentum. On the other hand, mean reversion strategies focus on the idea that asset prices cannot deviate from their fundamental values forever and will eventually revert to their true value. These strategies aim to identify when the underlying asset is overbought or oversold, and capture the turning points where market reversion is likely to occur. Common examples include the Relative Strength Index (RSI) and the stochastic oscillator.

Why might technical analysis work? An efficient market would suggest that there is no predictability in technical analysis, as all information is already priced in and future prices would follow a random walk. However, it may be too optimistic to assume that the market is able to price in all information instantaneously. Under-reaction to news that attracts less attention from investors and over-reaction to information that is highly visible and aligns with investor sentiment are widely observed in financial markets, leaving room for momentum and mean reversion strategies to be profitable. Additional behavioural effects such as the herding effect, where investors follow similar technical trading rules, can create a self-fulfilling prophecy where the price moves in the predicted direction merely due to the collective actions of technical analysts.

A backtesting example of a simple moving average crossover strategy

Now let’s look at an investment strategy based on trend following for the S&P 500 index to assess if technical analysis can be beneficial in timing the market. This strategy compares the current end-of-month stock prices with the simple moving average of the past ten months. If the current month's price is above the ten-month average, a long position in the index is taken; otherwise, the position is sold and moved to cash.

Looking at the sample from January 1990 to December 2023, the annualised returns of the S&P 500 (SPX) and the trend-following strategy yield similar returns, at 10.4% and 10.2% per annum, respectively. However, the volatility of the technical analysis strategy decreases to 11.3%, compared to the buy-and-hold strategy's 14.9%. Most notably, in terms of downside risk, the timing strategy has a maximum drawdown of 19.6%, compared to the S&P 500's 50.9%. Further analysis shows that the trend-following strategy avoids many of the drawdowns of the buy-and-hold strategy during turbulent periods without triggering many buy and sell signals. In fact, the average holding period is 398 days. Overall, this simple trend following example demonstrates how technical analysis can help to improve the performance of a simple buy-and-hold strategy by avoiding major drawdowns.

Stylised facts about technical analysis: Its use and profitability in financial markets

Do investors use technical analysis? Among practitioners, technical analysis is widely employed in the stock market, foreign exchange market, and futures markets. This has been corroborated by academic studies and professional investors’ survey.

How profitable is technical analysis used empirically? The effectiveness of technical analysis has been a subject of extensive discussion in the academic finance community. Most research provides positive evidence supporting the predictability of technical analysis.

Are all markets and methods equal? Technical analysis seems to work best for stock markets and foreign exchange markets, although it depends on which technique is used and for what time horizon. Trend-following methods seem to yield the best results, while shorter time horizons seem to be better suited than longer ones.

Future Trend: When technical analysis meets machine learning

Machine learning is revolutionising various industries, and the field of technical analysis for investors is no exception. Recent advancements have significantly improved the performance of machine learning approaches in recognising features in both images and numerical time series. While traditional economic theory assumes that asset prices reflect all available information, new machine learning techniques seem to suggest that this is not the case. As such, they offer valuable insights for the future of the industry, particularly in terms of improving price discovery and market efficiency.

Essential sources of information

Our analysts draw on publicly accessible information we consider to be reliable. For the compilation of the analysis, publications by domestic and foreign media and news services (e.g. Reuters, Bloomberg, VWD etc.), business publications, trade publications, statistics and rating agencies were used, together with information from the issuers of the analyzed securities – mainly via the Internet, but also in writing or by telephone. We also procure information from investment banks (sell-side research and primary research).

Reference regarding valuation rates

Unless otherwise stated or specified, the rates used in the analysis are normally the share prices provided by the news agencies Reuters and/or Bloomberg at the close of the stock exchange of the domestic market of the analyzed security or the relevant principal market of this security on the respective local stock exchange on the eve of the day of compilation.

Explanation of investment recommendations for stocks

We apply a “hybrid approach” (internal fundamental analysis combined with “theScreener”, an external, purely quantitative analysis tool). TheScreener is based on purely quantitative, i.e. computable variables such as (but not exclusively restricted to) profit adjustments of the past few weeks, stock valuation in relation to historical performance and comparison groups, the technical trend, performance in relation to the market etc. The assessment of the equity analysts, which is largely based on a qualitative analysis, does not need to match with the one of theScreener. For the overall judgement the assessment of the equity analysts overrides the one of theScreener. LGT Bank (Switzerland) Ltd. categorizes its analysis recommendations into five ratings: for a “Buy” recommendation we expect a relative outperformance compared with the sector. Only equities subjected to an internal fundamental analysis can be rated “Buy”. The recommendation “Attractive” is used for equities exclusively ranked by theScreener without any internal fundamental analysis as “slightly positive” or “positive”. A moderate relative outperformance versus the index is expected. For equities that we rate as “Hold” we expect a performance largely in line with the one of the sector. This can comprise both equities for which a fundamental analysis has been carried out as well as equities that theScreener ranks as “neutral” versus the index. The recommendation “Unattractive” is used for equities exclusively ranked by theScreener without any internal fundamental analysis as “slightly negative”. A moderate relative underperformance versus the index is expected. By contrast, “Sell” recommendations are based on the expectation of a relative underperformance compared with the sector. This can comprise both equities for which we are recommending “Sell” for fundamental reasons as well as equities that theScreener ranks as “negative” versus the index. Therefore the ratings always reflect a relative consideration versus the sector and/or specified index. The risk assessment is based on the individual judgement of the analyst (e.g. we assume a “high” risk for illiquid shares, highly indebted companies or shares from developing countries).

Reference regarding share valuation basis: The analysis compiled by LGT Bank (Switzerland) Ltd. are essentially based on secondary research relating to fundamental and quantitative analysis. Generally accepted valuation methods (valuation multiples, return figures, sector comparisons, comparisons with past valuations etc.) are used for this. The forecasts for the quantitative analysis are prepared with the help of mathematical-statistical procedures (see statements above concerning the analysis tool “theScreener”). Economic indicators such as interest rates, currencies, commodity prices and assumptions relating to the economy are included in the overall assessment. The mood of the market also affects the company valuation. Moreover, many of the approaches are based on estimates and expectations that may change quickly and without warning, depending on developments specific to the industry. Therefore, the recommendations derived from the analysis can also change accordingly. The investment judgements generally refer to a period of 6 to 12 months. However, they are also subject to market conditions and represent a snapshot of the situation. They may be achieved more quickly or more slowly or be revised upwards or downwards.

Explanation of investment recommendations for bonds

We employ both qualitative and quantitative methods to derive our recommendations, which are to be seen as relative to sector/quality peers among comparable maturities. “Buy” and “Sell” recommendations demand a qualitative in-house analyst opinion, in which we incorporate both historical and projected financial results and credit metrics as well as past and anticipated company and sector-specific observations and trends. We recommend “Buy” for a security for which we expect a strong relative outperformance compared to sector/quality peers among comparable maturities. We recommend “Sell” if we expect strong relative underperformance compared to sector/quality peers among comparable maturities. The ratings “Attractive”, “Hold” and “Unattractive” can be based purely on a quantitative approach, which includes the market price of credit risk, valuation of equities and associated instruments, corporate leverage, liability structure, size, and agency rating. We recommend “Attractive” for a security for which we expect a relative outperformance compared to sector/quality peers among comparable maturities. We recommend “Hold” if we expect an average performance compared to sector/quality peers among comparable maturities. We recommend “Unattractive” if we expect a relative underperformance compared to sector/quality peers among comparable maturities.

Definition of rating categories of S&P and Moody’s which are relevant for us:

AAA/Aaa: Borrower with highest credit quality. Default risk also virtually negligible over the longer term
AA/Aa: Safe investment, default risk virtually negligible but more difficult to assess in the longer term
A: Safe investment as long as no unforeseen events impair the overall economy or sector
BBB/Baa: Average investment. However, problems must be expected if the overall economy deteriorates
BB/Ba: Speculative investment. Defaults must be expected if the economic situation deteriorates
B: Highly speculative investment. Defaults are likely if the economic situation deteriorates

Risk information on LGT Sustainability Rating

To determine the LGT Sustainability Rating, the companies, countries and supranational organizations underlying the investment vehicles are assessed according to criteria defined by LGT with respect to the areas of environment (E), social issues (S) and corporate governance (G). Corporate and country-specific sustainability data (raw data) of external data providers feed into this rating. The LGT Sustainability Rating is a result based on criteria and calculation methods determined by LGT. It does not claim to be exhaustive, accurate or up to date. The LGT Sustainability Rating is not substantiated by LGT. Any liability of LGT is excluded. The LGT Sustainability Rating does not constitute advice, an offer, a solicitation or invitation to submit an offer; it is neither a basis for a decision nor a recommendation to buy or sell investment vehicles or other specific products, and does not constitute advertising for products or services. Advice from a qualified specialist before making an investment decision is recommended. Investments may be subject to fluctuations. A high LGT Sustainability Rating and a high ESG score do not guarantee a good or better performance of the investment vehicle or other products, in particular in comparison with an investment with a lower LGT Sustainability Rating. The LGT Sustainability Rating must be strictly separated from other analyses and assessments.

Risk information for US assets

This investment proposal might contain US assets located in the USA (known as “US situs assets”) which might trigger US inheritance tax consequences. This means, for example, that the estate of the decedent neither domiciled in the USA nor with US citizenship might become liable for tax payment to the US tax authority. Subject to a ceiling, non-US persons may enjoy tax exemptions and reductions if they are entitled to benefit from a double taxation agreement (DTA) which provides for such relief. LGT recommends that clients consult a qualified tax advisor for further information on US inheritance tax and the associated reporting obligations and tax liabilities in the USA. LGT does not automatically report tax liabilities to the Internal Revenue Service (IRS), the US tax authority.
