SPXF40D4 Contingent Income Memory Auto-Callable Securities — Simulation Report
Headline simulation results
Monte Carlo simulation, 20,000 paths. Because 95% of simulated paths auto-call early (median holding period only 6 months), the annualized figures reflect a very short, coupon-dominated holding period and should be read together with the total-return and holding-period numbers. The 1st-percentile outcome is still positive because a loss requires the underlier to finish below 60% of its start and coupons received to fail to cover that fall.
Detailed simulation metrics
| Metric (Monte Carlo, 20,000 paths) | Value |
|---|---|

| 99% confidence VaR (1 year, 1st-pct annualized return) | +0.95% |
| Expected holding period | 11.6 months (median 6 months) |
| Probability of early auto-call | 95.16% |
| Expected total return over the realized holding period | 11.22% |
How the product works (plain language)
- The security is linked to a single index, the S&P 500 Futures 40% Intraday 4% Decrement VT Index (SPXF40D4) — an S&P 500 futures index that deducts 4% per annum from its level.
- Contingent monthly coupon of 12.25%–13.25% p.a. (midpoint 12.75% p.a. modelled), paid only on a month in which the index closes at or above 60% of its initial level. A memory feature repays any previously skipped coupons once the 60% test is met again.
- Automatic early redemption: from month 6, on any monthly date the index is at or above 100% of its start, the note redeems at par ($1,000) plus accrued coupons and stops.
- If never called: at maturity the index ≥ 60% ⇒ par + coupons; the index < 60% ⇒ 1:1 downside off the initial level (e.g. −60% ⇒ $400, −100% ⇒ $0). Upside is capped — the investor never participates in index gains.
- Issuer credit risk applies to every payment.
Key statistics (annualized, 60-month horizon)
| Series | Expected return | Expected volatility | Probability of loss | 99% VaR (1 yr) |
|---|---|---|---|---|
| Structured product | 12.34% | 2.09% | 0.91% | +0.95% |
| Underlier (SPXF40D4 decrement index) | 10.95% | 11.95% | 4.75% | −11.45% |
| S&P 500 (price) | 15.31% | 12.19% | 3.40% | −7.77% |
| S&P 500 Total Return (dividends added) | 16.29% | 12.19% | 3.01% | −6.79% |
| Risk-free rate (1-yr avg repo/T-bill ≈ 3.75%) | 3.75% | 0.00% | 0.00% | 0.00% |
The coupon structure turns a volatile equity exposure into a low-volatility, high-coupon payoff: the product's expected return (12.34%) exceeds the underlier it references (10.95%) and dwarfs cash (3.75%), at a fraction of the underlier's volatility (2.09% vs 11.95%). It trails the un-decremented S&P 500 total return (16.29%), because the product caps upside and the referenced index gives up 4% per year.

Investment commentary
Points in favour
- Attractive headline income: a 12.25%–13.25% p.a. coupon in a structure that, in most paths, returns to par within roughly a year.
- Memory feature materially improves the odds of eventually collecting skipped coupons versus a non-memory structure.
- Low realized volatility (≈2%) and a positive 1st-percentile outcome: the coupon buffer means losses are rare in the simulation, and only appear when the underlier collapses below 60%.
- Short expected life (~12 months) limits exposure to the 4% annual decrement drag.
Risks to be aware of
- Capped upside — the investor receives no participation in index appreciation; returns are limited to par plus coupons.
- Decrement drag — the referenced index loses 4% every year whether the market rises or falls, so the 100%/60% thresholds sit on a level that erodes over time.
- Contingent, not guaranteed, coupon — coupons stop if the 60% barrier is breached; a deep event also triggers the 1:1 downside, and the worst simulated outcome is about −65%.
- Early-redemption / reinvestment risk — a 95% auto-call rate means the investor is likely to have capital returned early and face reinvestment at then-prevailing rates.
- Issuer credit risk — all payments depend on Morgan Stanley's ability to pay.
- Deep-tail outcomes: while rare in the simulation, a severe equity decline (below 60% of start on the decrement index) produces a large capital loss.
Figures are simulation-based estimates over a 60-month horizon and use a 12.75% p.a. coupon (midpoint of the 12.25%–13.25% range); the actual coupon will be fixed at pricing.
