Trigger SIP
A conditional SIP variant that activates an additional investment instalment only when a specified market condition — such as the index falling by a defined percentage — is met, allowing investors to systematically deploy more capital during market corrections.
Trigger SIP combined the discipline of systematic investing with tactical flexibility by tying incremental investments to pre-defined market events. While a regular SIP invested irrespective of market levels, a Trigger SIP remained dormant until a trigger event occurred. Common trigger conditions included a fall of 1 percent, 2 percent, or 5 percent in a benchmark index (such as Nifty 50 or Nifty 500) on any given day, or NAV falling below a specified threshold.
AMCs implemented trigger SIPs through their online transaction portals and mobile applications. Once the trigger was hit, the system automatically generated a purchase transaction for a pre-authorised amount from the linked bank account via a separate NACH or net-banking instruction. Investors needed to maintain sufficient balance in anticipation of triggers being hit, failing which the additional purchase was simply skipped.
The concept was closely related to the broader trigger facility offered by AMCs (which encompassed exit triggers as well), but the trigger SIP was specifically oriented toward entry at corrected price levels. Some platforms also offered index-level triggers — for instance, investing an additional ₹10,000 whenever the Nifty fell by more than 2 percent in a single session.
From a return perspective, trigger SIPs attempted to improve on plain vanilla SIP returns by concentrating incremental capital at lower entry points. However, empirical research on Indian equity markets showed that the improvement in XIRR was modest over long periods, given that markets spent more time rising than falling and infrequent triggers could leave substantial cash idle. The product was more relevant in volatile market phases.
SEBI's mutual fund circulars on the trigger facility addressed exit and switch triggers in detail, and trigger SIPs operated within the broader framework of AMC-level facility design. Investors needed to distinguish between the trigger facility (which also governed exit actions) and the trigger SIP, which was purely an additional purchase mechanism.
