Fundamental Trading Strategies: Analysis of Risk Reversal Indicators

risk reversal

Risk reversal is a practical fundamental analysis tool that can be incorporated into a trader's indicator system. A common limitation of foreign exchange trading is the lack of real-time volume data and indicators that can accurately measure market sentiment. Although commodity futures traders publish reports on traders' positions, providing public information on positions, there is usually a three-day delay in the data. Another effective alternative is to use a risk reversal indicator, which consists of a pair of options on the same currency pair (i.e. call and sell options). According to the parity relationship of the buy/sell options, the implied volatility of forward out-of-the-money options with the same expiration and strike price (Delta coefficient of 25) should theoretically be consistent. However, this is often not the case in practice. Volatility itself contains market sentiment, which makes risk reversals a powerful tool for measuring market sentiment. A number strongly biased towards buy options indicates that demand for buy options exceeds that for sell options. Conversely, a number strongly biased towards sell options reflects that the market has established more sell options positions due to greater demand. If the risk reversal value is close to zero, it usually means that the market is hesitant in the long and short direction and has not formed a strong unilateral tendency.

According to the risk reversal data shown in Table 1, we can observe that in the long run, the market is clearly biased towards Japanese yen buy options and US dollar sell options. The short-term risk reversal value of EUR/USD is close to zero, which usually corresponds to the market being in a range-oscillating environment. Traders can obtain the latest risk reversal data on some professional platforms as an analysis reference.

The abbreviations for each currency option are listed in Table 1, and most of the risk reversals are close to zero, indicating that the market has not formed a significant bias. However, the long-term risk reversal data for USD/JPY clearly shows that the market is strongly biased towards yen call options and dollar sell options.

How to apply risk reversal information

In order to make it easier to chart and observe, positive and negative numbers are usually used in the diagram to represent the option premium for buying and selling options, respectively. Therefore, a positive number indicates that the demand for buying options exceeds the demand for selling options, and the overall market expects the base currency to fluctuate upwards. Similarly, a negative number indicates that the demand for selling options is stronger, and the market expects the base currency to decline. When used prudently, risk reversals are a valuable tool for judging the overall direction of market positions. Although the signal it provides is not 100% accurate, it can still effectively indicate whether the market is currently in a bullish or bearish mood.

Figure 1 - EUR/USD and Risk Reversals The analytical significance of a risk reversal becomes particularly important when values are at extreme levels. Typically, we define extreme levels as a range of one standard deviation plus or minus the average risk reversal. When a risk reversal hits these levels, a contrarian trading signal is often sent, indicating that the currency may already be overbought or oversold based on market sentiment. This indicator is considered a contrarian signal because when the entire market is inclined to buy a currency bullish, the momentum for that currency to continue rising may be reduced; and if there is negative news, it will be easier for it to fall. Therefore, an extreme negative value usually implies an oversold situation, while an extreme positive value implies an overbought situation. Although the buy-sell signals provided by risk reversals are not perfect, they can convey additional market sentiment information and assist traders in making more comprehensive decisions.

Risk reversal transaction case analysis

The first example is the EUR/USD. As can be seen from the relevant charts, the risk reversal data with a Delta coefficient of 25 is often used as a leading indicator of the movement of the EUR/USD exchange rate. For example, when the risk reversal suddenly drops to -1.39 on a given day, it signals that the market has a strong bearish bias. This later proved to be a reliable contrarian indicator, and the EUR/USD subsequently rallied hundreds of points within a few days. When the price rose rapidly again, the risk reversal quickly rose to 0.67, which seemed to continue the uptrend, but the EUR/USD subsequently proved that the bulls had misjudged and experienced a deeper decline. Although there are many examples of risk reversals signaling small-scale counter-trend movements, it is also possible to see several major volatility cues per year. For example, on August 16, the risk reversal reached 1.43, signifying a very high level of bullish sentiment. In the three weeks since, the EUR/USD has lost hundreds of points. A month later, when the risk reversal surged again to 1.90, this corresponded to another staged top for the EUR/USD, followed by a deeper decline in the market.

The next example is GBP/USD. As shown in Figure 2, risk reversals are extremely effective in identifying extreme overbought and oversold states. To further illustrate how risk reversals indicate the timing of a market turn, reference horizontal lines for buying and selling can be added to the GBP/USD chart. Due toforeign exchange marketWithout consistent volume data, traders sometimes struggle to sense the direction of the market, and risk reversals help measure the overall market sentiment temperature. In a trading environment such as Ava Forex, multi-dimensional analysis combined with such indicators can improve the understanding of market trends.
