📌 Chart Signals - How Much Should You Trust Them?
💬 Technical analysis is just a support tool, not an absolute standard
Technical analysis, which analyzes stock charts, is a method used by many investors, but you should never blindly trust it.
Charts reflect past market data, not predict the future. Especially in the US stock market, long-term performance and fundamentals tend to have a greater impact on stock prices, so relying only on chart analysis can be risky.
Chart signals can be used as reference material for making investment decisions, but they should not be the sole basis for trading.
1️⃣ What is Technical Analysis?
Technical analysis is a method that tries to predict future price movements based on data such as past price movements and trading volume. The following tools are commonly used:
① Moving Averages
- Use moving averages like the 50-day and 200-day lines to understand price trends.
- Analyze golden crosses (bullish signals) or death crosses (bearish signals) based on moving averages.
② Support and Resistance
- Find patterns where stock prices bounce or face resistance at certain price levels to decide trading timing.
③ Volume Analysis
- Check whether trading volume increases along with price increases to evaluate the reliability of an uptrend.
④ Technical Indicators
- Use indicators like RSI (Relative Strength Index) and MACD (Moving Average Convergence Divergence) to analyze trading signals.
2️⃣ Limitations of Technical Analysis
While technical analysis can be useful to some extent, you must clearly understand its limitations.
① Institutional investors have a large presence in the US stock market
- Unlike the domestic stock market where individual investors are more prominent, the US market has a high proportion of institutional investors, and they often focus on company fundamentals rather than technical analysis.
② Chart patterns are based on past data
- Charts reflect data that has already occurred, so they cannot perfectly predict the future.
- Even when looking at the same chart, interpretations can differ from person to person.
③ Risk of false signals
- Even when certain chart signals appear, the market often doesn't move in the expected direction.
- Trading based solely on chart signals has a high probability of losses.
④ Company performance and market conditions are more important
- In the US stock market, company performance is a key factor that determines long-term stock price direction.
- You should consider company earnings reports, economic indicators, and market sentiment together, rather than just short-term chart signals.
3️⃣ The Right Way to Use Chart Analysis
You don't need to completely exclude charts, but it's important to use them correctly.
① Understand long-term trends
- Use 50-day and 200-day moving averages to analyze long-term trends.
- It's important to see if the trend continues rather than being swayed by short-term fluctuations.
② Combine technical analysis with fundamental analysis
- Even when chart signals appear, you should check if the company's performance supports them.
- Consider profit growth and market conditions together, not just simple patterns.
③ Take a probabilistic approach
- Chart signals are not 100% accurate, so don't make investment decisions based on one signal. You should make comprehensive judgments considering multiple factors.
④ Focus on long-term investing rather than short-term trading
- Since the US market tends to trend upward over the long term, it's more important to look at long-term growth potential rather than short-term chart signals.
4️⃣ Q & A
Q1. Can I make profits with chart analysis alone?
A1. It's difficult to make profits using only chart analysis. Especially in the US stock market, company performance and economic conditions are more important factors, so it's better to use charts as reference material.
Q2. Which chart signals are most reliable?
A2. The 50-day and 200-day moving averages and volume analysis are the most reliable. However, chart signals are only support indicators, and you must always analyze performance and market conditions together.
Q3. Should I learn chart analysis for short-term trading?
A3. While chart analysis is needed for short-term trading, it's not recommended for beginners because the success rate is low and volatility is high. Focusing on company fundamentals and long-term growth potential is a safer investment method than chart analysis.
In conclusion, chart signals are just one reference for making investment decisions and cannot be an absolute standard. In the US stock market, long-term performance and fundamentals are more important factors, so it's advisable to use chart analysis as a supplementary tool.
