Since the start of 2022, the capital markets have been quite volatile. Moreover, it has been raining with global macro-economic events such as higher inflation, the Russia-Ukraine war, China lockdown, and rate hikes, which have left much uncertainty among the market participants.
During such turbulent times, investors often look for investment solutions, which may help reduce the heightened volatility.
The low volatility strategy:
Among several factor-based investing strategies, the low volatility factor includes stocks with historically stable price movement.Further, this strategy selects companies with relatively mature business models and stable earnings visibility.
Most investors suffer from loss aversion bias, i.e. the pain of losing is twice as much as the pain of winning. Therefore, in times of market free-falls, the low volatility strategy may help to decrease the magnitude of the fall.In addition, having a low volatility strategy’s support may also minimize the panic decisions made during the high drawdown phase.
Recent Performance of the low volatility strategy:
Let us see how the low volatility strategy fared against the Nifty 200(herewith referred to as “markets”).
Exhibit-1: Performance (LHS) and Drawdown (RHS) of indices as mentioned
Disclaimer/Source: MOAMC, niftyinces.com, Asia Index; Data as of25 July 2022.The above graph is used to explain the concept and is for illustration purpose only and should not be used for development or implementation of an investment strategy. Past Performance may or may not be sustained in future.
The YTD returns for the low volatility strategy stand at -2.3%, while that of the market is at -3.3%, i.e. an outperformance of 1%. The former outperformance may not seem much; however,the maximum drawdown faced by the low volatility strategy during this time has been -13% against -16.5% of the market.This isan outperformance of 3.5%. The data puts the proof in the pudding and demonstrates that the low volatility strategy is performing as expected from its characteristics.
Nevertheless, it is interesting to see why the low volatility strategy falls less than the market. A quick look at the strategy’s composition will tell us which sectors/stocks have the most significant representation in the strategy index.
Exhibit-2: Sector Composition of S&P BSE Low volatility index
Disclaimer/Source: S&P BSE; Data as of 30 June 2022 . The sectors mentioned herein are for general assessment purpose only and not a complete disclosure of every material fact. It should not be construed as investment advice to any party. Past Performance may or may not be sustained in future.
Let’s look at the top sectors by weight. Defensive sectors such as FMCG and Consumer Discretionary occupy the lion’s share,i.e. 34% and 22.5%, respectively. These sectors generally exhibit inelasticity towards high prices and get less impacted.Conversely, cyclical sectors such as industrial and commodities are absent or occupy little weight in the index protecting it from steep falls.
We saw above that the low volatility strategy fell less than the markets in 2022, but was it the case during the past market falls as well.
Turning the pages into history
Let us analyze how the low volatility strategy fares during different levels of market falls. Here, we put the strategy through the test of time to determine whether it stands out.
Exhibit-3: Drawdown Analysis: 2007-2022
Source: MOAMC, niftyindices.com, S&P BSE; Data as of 25 July 2022; Markets – Nifty 200 TRI, Low volatility – S&P BSE Low Volatility TRI The above table explains the concept, is for illustration purposes only, and should not be used to develop or implement an investment strategy. Note that the assumptions listed above are central to the illustration.
In the table above, Column (B) shows the average drawdown of markets each time it fell by X%, i.e. mentioned in column (A). Similarly, column (C) shows the average drawdown of the low volatility strategy during the same period.
We can observe that the low volatility strategy outperformed the broader markets at each market fall. Further, we see an exciting trend that as markets fall deeper, the outperformance of the low volatility strategy against the market also increases. For example, at 20% market drawdown, the outperformance by low volatility is ~4%, but at 35% market drawdown, the outperformance jumps to ~14%. Thisshows that the low volatility strategy has also behaved as expected in the past.
The low volatility outperformance stems from several behavioural biases of investors, such as the lottery effect, overconfidence bias and asymmetric nature of returns.
As observed above, with sufficient historical data and empirical evidence, we can see the presence of the low volatility anomaly in the market. The low volatility strategy exploits human behavioural biases to limit the downside risk. So, essentially, the strategy falls less so that it doesn’t have to rise as much to outperform the markets. Exposure to such a strategy can help you
through market falls more smoothly.
