10.10 Systematic Transactions and Their Operational Aspects

Systematic Investment Plan

A SIP invests a fixed amount into a scheme at fixed intervals — most commonly monthly, though daily, weekly, fortnightly and quarterly frequencies exist.

Rupee cost averaging

Because the amount is fixed and the NAV varies, more units are bought when the NAV is low and fewer when it is high.

Worked example. INR 10,000 invested monthly over four months:

Total invested   = INR 40,000
Average NAV      = (50 + 40 + 32 + 50) / 4 = INR 43.00
Average cost     = 40,000 / 962.50        = INR 41.56
Value at month 4 = 962.50 x 50.00         = INR 48,125

The average cost of INR 41.56 is below the average NAV of INR 43.00. That gap is rupee cost averaging, and it arises automatically from investing a fixed sum rather than a fixed number of units.

Note what it does and does not do. It reduces the impact of entry timing. It does not guarantee a profit, and in a market that only rises a lump sum invested at the start would have done better.

The behavioural benefit

The larger benefit is behavioural. A SIP removes the monthly decision, so the investor does not have to feel confident in order to invest. It converts investing into a standing habit and is the principal reason Indian mutual fund flows have become markedly less sensitive to recent market performance.

SIP variants

Top-up SIP is the most under-used and most valuable. An investor whose income rises 8% a year but whose SIP stays fixed is quietly reducing their savings rate every year.

Systematic Transfer Plan

An STP transfers a fixed amount at fixed intervals from a source scheme to a target scheme within the same fund house.

The standard use is deploying a lump sum into equity gradually: park in a liquid or ultra-short scheme and transfer a fixed amount monthly into an equity scheme. The money earns a return while it waits, and entry into equity is staggered.

Each STP instalment is a redemption from the source scheme. Capital gains arise on every transfer, exit load may apply, and stamp duty is charged on the units issued in the target scheme. Where the source is a Specified Mutual Fund, each transfer produces short-term gains taxed at the investor's slab rate. This is the cost of staggering, and the investor should be told about it before the STP is registered.

Systematic Withdrawal Plan

An SWP redeems a fixed amount at fixed intervals and credits it to the investor's bank account.

It is the appropriate structure for an investor needing regular cash, and the reason is tax:

Only the gain element within each withdrawal is taxed under an SWP, whereas the entire IDCW is added to income. For a retiree drawing a monthly sum from an equity-oriented holding, the difference over a year is substantial.

The caution: withdrawing more than the portfolio earns depletes the capital. An SWP set at a rate above the sustainable withdrawal rate will exhaust the corpus, and the investor should see that arithmetic before starting.

Operational Aspects

Mandate registration. Systematic debits run on a NACH mandate registered with the investor's bank, which takes time to activate — commonly a few weeks. The first instalment date must allow for this, and an investor expecting a debit the following week is often disappointed.

Minimum amounts and instalments. Each scheme states a minimum instalment and a minimum number of instalments in its documents.

Instalment dates. Investors choose from dates the AMC offers. Where a chosen date is a non-business day the instalment is processed on the next business day.

Failed instalments. Insufficient balance causes the instalment to fail. Repeated failures — commonly three consecutive — can cause the SIP to be terminated, and the bank may levy its own charge.

Cut-off and realisation. Each instalment is a separate purchase subject to the ordinary cut-off and realisation rules.

Per-instalment treatment. This is the point that generates the most investor surprise, and it applies across all three facilities:

• Exit load period runs from each instalment's own date
• ELSS lock-in of three years applies to each instalment separately
• Holding period for capital gains is measured per instalment
• Stamp duty at 0.005% is charged on each instalment

Cancellation. A systematic facility may be cancelled with prescribed notice, typically some weeks before the next instalment, since the mandate must be withdrawn from the banking system.
