Tech Analysis in Stocks: Comprehensive Guide for Investors 2025

Tech analysis in stocks is an indispensable method for any investor looking to understand the dynamics of modern financial markets. Based on the study of past prices and traded volumes, it allows one to anticipate future movements of assets, whether they be stocks, indices, currencies, or commodities. Through this comprehensive guide, discover how to leverage tech analysis for your investment strategies, its added value compared to fundamental analysis, and how to progress systematically from beginner to expert in financial markets.

Introduction to Tech Analysis in Stocks

Tech analysis in stocks relies on the belief that all factors influencing a security's price are already integrated into its course. By analyzing charts and indicators, investors can identify trends, predict reversals, or detect relevant entry and exit points. Unlike fundamental analysis, which focuses on the financial health of companies, tech analysis is based solely on the evolution of prices and volumes to spot recurring patterns, regardless of sector or asset type.

Goals of Tech Analysis

The main goals of tech analysis are defined as follows:

  • To identify major market trends to follow the dominant movement and avoid going against the trend.
  • To recognize levels of support (thresholds under which an asset rarely falls) and resistance (thresholds that the price finds difficult to break through).
  • To detect buy or sell signals from price configurations, trend breaks, or technical indicators.
  • To measure momentum, i.e., the strength of a current trend, using tools such as RSI or MACD.
  • To anticipate trend reversals to seize the optimal moment for entry or exit.

For an investor, integrating tech analysis into their strategy often helps better manage risk and increase the profitability of their stock investments.

Advantages and Limitations of Tech Analysis

Tech analysis offers multiple advantages that explain its widespread adoption:

  • Objectivity: it relies on concrete historical data, eliminating the emotional aspect of investment decisions.
  • Universality: its methods are applicable to all types of markets and assets (stocks, indices, ETFs, commodities, cryptocurrencies).
  • Accessibility: most trading platforms now offer interactive charts and a wide range of indicators for all investor profiles.
  • Reactivity: it enables quick identification of short-term trading opportunities or major reversal signals.

But technical analysis is not without its limitations. Overconfidence in an indicator or the isolated use of this method can lead to hasty decisions. Additionally, fundamental analysis provides a crucial macroeconomic and microeconomic perspective essential for stabilizing the selection of long-term assets, especially in stock markets.

The Key Concepts of Technical Analysis in the Stock Market

To master technical analysis in the stock market, you need to know the following foundations:

The Different Types of Charts

Charts are the basic language of the technical investor. The main ones are:

  • Linear Chart: it traces the closing price for each period, giving a simplified but effective view of global trends.
  • Japanese Candlestick Chart: the most popular for the modern investor, it displays the opening, closing, highest, and lowest prices of each session, coded by colored rectangles (bodies and shadows). It facilitates the identification of reversal or continuation patterns.
  • Bar Chart (or bar chart): similar to candlesticks, it allows for quick reading of the daily range, but offers fewer visual cues.
  • Histograms: used to visualize the volume or strength of an indicator (MACD, trading volume, etc.).

In practice, the Japanese candlestick chart remains the reference in technical analysis for its rich information content.

Trends and Chart Patterns

Reading trends is the foundation of technical analysis:

  • Bullish Trend: a sequence of higher lows and higher highs. It is characterized by preferred buying configurations.
  • Bearish Trend: a series of lower highs and lower lows, an environment conducive to short selling positions (short selling, options, etc.).
  • Lateral Trend (Range): prices oscillating between two clearly defined boundaries, a strategy based on buying at support and selling at resistance.

Chart patterns allow anticipating the continuation or reversal of a trend. Among the most famous figures, we have the double bottom, the double top, the head and shoulders pattern, ascending or descending triangles, rectangles, flags... Their automatic recognition is facilitated by many tools on modern investment platforms, reinforcing their usefulness in building trading or investment strategies.

Support and Resistance Levels

Support and resistance levels are the essential landmarks of any stock market investor:

  • A support level is a zone where the buying pressure tends to outweigh the selling pressure, stopping or mitigating the fall of the share.
  • A resistance level is a psychological or technical barrier where the selling flow eventually prevents the continuation of the rise.

Defining these levels precisely allows optimizing entry and exit points, and analyzing the underlying market structure to anticipate major breakouts.

The Indispensable Technical Indicators

Technical indicators are mathematical tools applied to prices and traded volumes. They complement graphical analysis and facilitate decision-making. The most popular ones are:

  • Moving averages (SMA/EMA): smoothing of price over a given period to determine the general trend and crossing signals.
  • RSI (Relative Strength Index): measures the strength or weakness of an asset in terms of momentum. A high RSI indicates an overbought asset, while a low RSI indicates an oversold asset.
  • MACD: combines two moving averages to detect changes in trends and identify divergences.
  • Bollinger Bands: volatility bands that help identify overbought or oversold zones and periods of contraction/expansion of volatility.
  • Volume: essential for validating or invalidating a price movement; a rise accompanied by strong volume is considered more robust.

Used intelligently, these indicators strengthen the relevance of each detected signal, while keeping in mind that they cannot guarantee absolute results.

Case Studies: Technical Analysis on a London Stock Exchange Listing in 2025

To illustrate the practical use of technical analysis, let's take the example of a small-cap listed on the stock exchange of London, in the oil exploration sector: Borders & Southern Petroleum plc (symbol: BOR.L). Understanding its stock data and technical dynamics is essential for any investor or analyst.

Stock Profile (updated November 2025)

  • Symbol: BOR.L
  • Market: London (LSE AIM)
  • Industry: Energy
  • Sub-industry: Oil & Gas Exploration & Production
  • IPO Date: April 2005
  • Number of Shares Outstanding: Approximately 737 million
  • Current Price: Approximately 0.07 GBP or 7 pence, which is equivalent to approximately 0.08 €
  • Market Capitalization: Between 11 and 13 million GBP (around 12 to 15 million euros depending on exchange rate fluctuations)
  • P/E Ratio: Not applicable (non-profitable company to date)
  • Dividend: No dividends paid
  • Beta: Not disclosed or not relevant (no reliable data published in 2025)
  • Average Daily Volume: Between 2 and 10 million shares depending on the period, indicating relative liquidity for such a small market capitalization.

This type of company often attracts speculative investors seeking strong variations and turnaround scenarios, making technical analysis indispensable for evaluating moderate-risk intervention zones.

Applied Technical Analysis: How to Proceed in 2025?

Here is how a French or European investor can proceed with technical analysis on this type of value:

  • Use candlestick charts to appreciate the dynamics of recent sessions and the intrinsic volatility of the stock.
  • Plot the main support levels (for example, on BOR.L, the zones between 6.5 and 7 pence) and short-term resistance levels (around 7.2 to 7.6 pence, or even 8 pence in case of a massive rebound).
  • Anchor your analysis on transaction volume: a surge in volumes upon a bullish breakout validates the strength of the move, while a drying up often signals the exhaustion of the trend.
  • Get complementary signals through moving average crossovers (10, 20, or 50 periods for very short term, 200 periods for the underlying trend).
  • Watch reversals via the RSI: an RSI below 30 may indicate excessive pessimism and a potential rebound, whereas an RSI above 70 signals technical overheating in the short term.

It is wise to complement your analysis with minimal fundamental dimensions: evaluate the company's communication, financial situation, and progress of major projects. This allows you to confirm the relevance of technical analysis or to signal a discrepancy between price and economic reality.

Fundamental Analysis vs Technical Analysis Comparison

Type of Investor "Value" investor, institutional, buy & hold Active trader, chart analyst, opportunistic investor
Main Tools Financial statements, financial ratios, sectoral analysis Charts, moving averages, RSI, MACD, Bollinger Bands, volumes...
Limits Sometimes out of sync with the market, sensitive to announcement effects Risk of false signals, relevance varies according to the quality of volumes and data

Best Practices for Technical Analysis in Stock Trading

To progress and solidify your approach to technical analysis, implement these essential tips:

  • Define your investment horizon: your technical analysis will differ whether you are day trading or investing for several months.
  • Adapt your indicators: avoid an overabundance of contradictory indicators. It is preferable to select three to five complementary tools.
  • Always check the volume: a price movement without volume is less reliable, especially on small capitalizations (small caps) like Borders & Southern Petroleum.
  • Test your strategies: use backtesting tools to validate your buy or sell signals on historical data. Platforms often allow this type of simulation for free.
  • Integrate risk management: systematically place stop-loss orders to limit potential losses if the market moves against you.
  • Stay disciplined: avoid forcing a signal or going against an obvious trend on the chart.

Financial Indicators and Key Data to Follow in 2025

  • Average volumes: monitor the evolution of volumes to anticipate major trend changes.
  • Valuation ratios: on non-profitable values, the PER (Price/Earnings Ratio) will not make sense: prefer instead to monitor cash, level of debt, and perspectives of major projects.
  • Liquidity: on low-capitalization stocks, low liquidity implies more volatility and requires specific tactics (limit orders, reduced position sizes).
  • Sector dynamics: the "Energy – Oil & Gas Exploration & Production" sector is structurally volatile, dependent on oil prices and regulatory/economic announcements.

Optimize Your Investments through Technical Analysis – Practical Cases

Experienced investors combine technical analysis with active risk management:

  • On stocks with strong consolidation phases, a chart break (such as breaking a resistance line) coupled with a surge in volumes can signal an optimal entry point.
  • In a range, buying at support and taking profits at resistance optimizes performance on low-volatility stocks.
  • During a strong trend, tracking via exponential moving averages allows maintaining the position as long as the momentum is not challenged by a clear break.
  • The judicious use of chart patterns (triangles, flags...), combined with position sizing management, limits the risks of significant losses.

Resources and Evolution of Technical Analysis in 2025

In 2025, investors benefit from increasingly advanced tools for practicing technical analysis: interactive platforms, analysis bots, trading algorithms, dedicated mobile apps for stock analysis or personalized alerts. These technologies enable more responsive decision-making but require rigor and discernment.

If you are new to investing, it is recommended that you seriously educate yourself, practice on demo accounts, and regularly consult financial news on reputable websites to refine your understanding of the markets.
