The general market should be studied closely every day, since reverses in trends can begin on any one day. I emphasize this practical method rather than that of interpreting other subsidiary indicators that are supposed to tell you exactly what the market should be doing or listening to the many stock market letter writers or technical analysts that pore over twenty indicators and tell you what they think the market should be doing. Market letters sometimes may create doubt, uncertainty and confusion in an investor’s mind. Markets tend to go up when people are skeptical and disbelieving.
Learn to interpret a daily price and volume chart of the general market averages. If you do, you can’t get too far off the track. You really won’t need much else unless you want to argue with the trend of the market.
Experience teaches you that continually arguing with the market can be very expensive, That’s how people go broke!
