Long before the Western World had even understood that the study of charts might be beneficial, the Japanese were constructing and studying rice futures charts in a system which today we call candlestick charting. Before candlesticks charts, everyone was using bar charts but today you hardly ever see a bar chart.
What most investors do not know is that there are literally hundreds of candlestick formations each of which have been extensively analysed and have their own particular interpretations. If you are interested in this, you should get hold of a copy of Japanese Candlestick Charting Techniques: A Contemporary Guide to the Ancient Investment Techniques of the Far East, (1991). The author of the book is Steve Nison.
In candlestick charting, each day’s trade is regarded as a battle between the bulls and the bears which is visible in the opening, highest, lowest and closing prices. So, the body of the candle connects the opening and closing prices. A red body shows that the share closed below the open and a green candle shows that the close was above the open. The shadows (i.e. the lines above and below the body) connect the highest and lowest prices that the share reached during the day’s trade.
Candlestick charting features many different types of candles which can help you to see which way the market is moving.
One of the less common ones is a doji star. This is a candle with a very thin body – in other words where the opening and closing prices are very close – but very long upper and lower shadows – which shows that during the trading day, sentiment swung heavily from being very positive to being very negative – but ended up almost unchanged on the day. Consider the example of a doji star below:

Doji stars usually occur at the top or bottom of a trend and are indication that the direction of the trend is about to change.
Since the S&P500 reached its all-time high on 2nd June 2026 (at 7609.78), it has been in a triangle formation. Triangles are usually associated with periods of uncertainty, where the level of uncertainty diminishes until the market decides the future direction of the trend by breaking the upper or lower trend lines decisively. The chart below begins with the low point of Trump’s Iran war correction on the 30th of March 2026.

Shortly after it started going up, the index had a clear hammer formation followed by a gap. The hammer is a very bullish formation which shows that in the battle between the bulls and bears on that day, the bears tried hard to pull the index down, but ultimately could not succeed and it ended slightly up on the day, with the bulls in the ascendancy. The gap which followed that on the next day shows the extent of the bullish sentiment. Then there was a smaller gap in May before the record high was reached.
You will notice that the index has been oscillating since then but that each oscillation has been smaller than the previous one, giving rise to a triangle formation. Last Thursday there was a clear doji star formation. We expect that the index will break up out of the triangle in the next few days.
