Thematic investing can be exciting, but it can also be unforgiving. When a sector captures public attention, prices tend to rise quickly, and then fall just as abruptly when sentiment cools. Defence stocks have shown this pattern repeatedly. Followers of the HAL Share Price have seen strong rallies followed by sharp pullbacks within short spans. The BEL Share Price has displayed comparable swings, rewarding those with patience and testing those who bought at peaks. Learning to manage this volatility is essential for anyone adding the theme to a portfolio.
Why Thematic Stocks Swing Widely
Several factors tend to boost thematic moves: increased retail participation, social media buzz, and inflows of fresh money from mutual funds – the last of which can cause price surges even if the near-term outlook appears bleak. Whereas fund outflows can trigger selling.
Events such as budgets, contracts, trials, and statements also play a role. Since valuations are typically high, any downward revision can lead to disproportionately large falls in prices.
Deciding on How Much to Buy
Portfolio or position sizing is the most important risk management tool. A theme that one is excited about should constitute only a small part of the overall portfolio. Many experts advise that one’s allocation to any particular theme must be limited to a particular percentage (based on one’s age, income, and risk profile) of the overall equity allocation.
One must also consider whether one’s other mutual funds or direct holdings already have exposure to the theme – particularly if one is considering direct stock purchases. After all, diversification is a virtue, unless one is certain of the fundamentals of the sector or company one is investing in.
Staggered Buys and Systematic Investments
One must avoid the temptation to invest a large chunk of money at any given time when the theme is in the news. Instead, one must try to split the proposed allocation into smaller, regular investments. This could be done systematically, using a monthly SIP or otherwise. This way, one buys at a lower average price and also reduces the risk of buying at a market peak.
In the case of mutual funds, one could also look at diversified funds with exposure to this theme as well as other industrial or theme-based funds. This way, risk is diversified across companies without diluting the exposure to the theme.
Using Fundamentals as a Benchmark
During periods of turbulence, fundamentals can be a good guide. Monitoring things like order books, margins, and cash flows can help determine if the company is doing well despite the downward slide in prices. Similarly, such factors may also be a warning sign if things are going downhill.
It can be a good idea to set parameters for increasing or reducing exposure to a theme or company based on its fundamentals. For instance, one may decide to add to a position if valuations reach a certain level or if there is a change in some key fundamental. One must set such rules and then follow through on them.
Rebalancing and Booking Profits
If one has made a lot of money on a particular thematic play, it may make sense to rebalance the portfolio by booking profits and moving on to other themes. This may be painful given the potential for continued gains, but it is a good way to limit downside risks if the theme undergoes a sudden reversal. One must rebalance systematically – once or twice a year – rather than getting swayed by day-to-day moves. One must also keep track of the tax implications of both short-term and long-term gains and losses.
Emotional Risk Management
Above all, one must avoid the twin traps of fear and greed. Whereas fear may drive one to sell at the wrong time, greed may prevent one from booking profits. One must keep a log of reasons for investing in a theme as well as red flags that should prompt a reassessment of the investment thesis. These logs can be a good way to overcome the emotional barriers to selling and buying.
One must avoid using leverage since it can exacerbate losses as well as prevent one from selling at the right time due to the need to offset leverage. One must also maintain an emergency fund as well as adequate insurance cover so that one cannot be forced to sell investments at an inopportune time.
The Next Step
While thematic investing can be rewarding, one must always remember that it is a means to an end rather than an end in itself. It makes sense to stick to a well-diversified portfolio with a thematic exposure that one is comfortable with. One must remember that temporary falls in prices can often be large, and one must be prepared to withstand such volatility. With the appropriate risk management strategies in place, one can participate in the upside while limiting the downside.
