In case of foreign exchanges traders and other markets the momentum strategy would imply acquiring the asset which is on the rise, while selling the asset which is on a decline. This reasoning is clear enough due to the fact that price increment can create a notion that the analogy is of the asset, and people tend to sell that inflated asset till the price completes a jump which is an unrealistic thought process hence the idea is an investment glance through is slicked.
In this paper we will attempt to connect all the dots together by first explaining a real world trading scenario we will focus on clearer concepts so that beginner-and-intermediate traders do not struggle.
What is Momentum Trading?
Essentially, it comprises the thought that price levels keep trending in a certain direction. It is constructed on:
Price Trends: Assets price performance in the upwards or the downwards direction for a particular time frame.
Volume Confirmation: High volumes that affirm the price level.
Behavioral Factors: Most of the time, traders join the buying/selling band wagon.
Step by Step Process on How to Build a Momentum Strategy
- Defined There Zone of Assets
Firstly there is a need of defining the market or class of assets which one is to start trading with these could be;
Shares from a certain index e.g Nifty 50 or S&P 500.
Currency, ETFs, commodities which will also be merged into one category as for this purpose we only want to focus on shares from Nifty 50 index.
- Momentum Indicators
A common trend i indicator is RSI. It measures the strength, or the velocity of price movement, for a stock or any asset. Another indicator is MACD which measures the momentum of price changes. A ROC indicator shows the rate of change of price in a certain period of time. And SMA trend indicator looks for the smoothness in price changes.
As an example, let’s simplify things by just using the 12-month price return as the most basic momentum indicator at the moment.
- Setting Rules for Opening and Closing a Position
For any strategy an opening and closing rule is important to implement the strategy properly Once again we will outline them here:
Opening Rule: Buy shares of 10 companies with the highest 12-month returns over the last time period.
Closing Rule: In case the stock falls out of the top 10 or the scrip does not outperform the index for a reasonable time period, sell the shares.
- Strategy Revaluation
This is the key step in settlement process of any strategy as it ensures historical validation of your strategy:
Locate reliable data with at least 5-10 years worth of historical price records of Nifty 50 stocks.
Next, determine the 12 months rate of return on the stock and rank them accordingly.
Thirdly, Set the buy and sell price to trigger when when the desired stock is selling above the targeted ranking so as to simulate a portfolio rearrangement on a monthly or quarterly time basis.
Reevaluation Example Results :
Annualized Rate of Return: 16% in contrast to the 50 Nifty Index which has an annualized rate of 12%.
Max Drawdown : 25% when compared with the index’s 20% caused by the assets volatility.
Sharpe Ratio: 1.2 which reflects reasonably good Sharpe Ratio in risk performance
- Risk Management
The use of momentum strategies comes with a considerable amount of risk as it requires the purchase of stocks at a high entry price point. You will need to take the following precautionary actions:
Position sizing: Commit an equal value into each selected stock to spread risks.
Stop-loss orders: Sell the shares of the party automatically if the value price falls below a predetermined level (for instance, 10%).
Portfolio diversification: Make investments across multiple industries so as to lessen firm specific risks.
- Monitor and Adjust the Strategy
Lastly, do remember that the way the economy operates changes and so must your strategy. Keep a keen eye on:
Indicator effectiveness (e.g. does 12 month return indicate a trend)
The frequency of re-balances so as to achieve the best possible return with least expense ratios.
Real-World Example
Let’s take the hypothetical example of a strategy being implemented in January 2023:
Defining the Universe: Take All the Stocks Within Nifty 50.
Calculating 12 month return: Look for the prices of the top ten best performing stocks in the market for 2022.
Calculating Capital Required: Allocate the chosen stocks with an equivalent ratio of 10,00,000 rupees (1,00,000 for each).
Rebalancing: Quarterly realignment of the portfolio for example to April to replace poor performing stocks.
Challenges of Momentum Strategies
Market reversals: Sharp reversals in the market can be quite damaging.
High Turnover: Regular buying and selling adds on the costs of the transactions and increase taxes.
Overcrowding: The common trades undertaken especially limited ones may not be very profitable.
Improving the Strategy
Embed with Risk Metrics: Position stock volatility filters for stock selection purposes.
Sector Exposure: Put into place concentration limits for any one sector.
Leveraging: Use algorithmic trading tools to effect and rebalance trades quickly.
Conclusion
In short, momentum strategies can be a powerful weapon for those traders who are willing to go with the trends. At the same time, care and great vigilance is needed. By employing the techniques outlined in this example, traders should be able to develop an approachable manner in which to obtain momentum while trying to match it up with risk.
