How do cliquet options accumulate returns through their reset mechanism, and why are they popular in structured products?

A cliquet option is a series of consecutive forward-starting options where each sub-period's strike is set (reset) to the prevailing spot price at the start of that period. Returns are typically accumulated with local caps and floors per period, plus potentially a global floor on the total payoff.\n\nReset Mechanism:\n\n`mermaid\ngraph LR\n A[\"Period 1
K1 = S0
Return: S1/S0 - 1\"] --> B[\"Period 2
K2 = S1
Return: S2/S1 - 1\"]\n B --> C[\"Period 3
K3 = S2
Return: S3/S2 - 1\"]\n C --> D[\"Period 4
K4 = S3
Return: S4/S3 - 1\"]\n D --> E[\"Total Payoff
Sum of capped/floored returns\"]\n`\n\nAt each reset date, the option locks in the return from the prior period and sets a new at-the-money strike for the next period.\n\nPayoff with Caps and Floors:\n\nPer-period return: R_i = max(Floor, min(Cap, S_i/S_{i-1} - 1))\n\nTotal cliquet payoff: Notional x max(Global Floor, sum of R_i)\n\nWorked Example:\nSilverbrook Wealth issues a 1-year equity-linked note with a quarterly cliquet on the Apex 500 Index. Terms: local cap 5%, local floor -2%, global floor 0%, notional $1,000,000.\n\n| Quarter | Start | End | Raw Return | Capped/Floored |\n|---|---|---|---|---|\n| Q1 | 4,200 | 4,536 | +8.0% | +5.0% (capped) |\n| Q2 | 4,536 | 4,310 | -5.0% | -2.0% (floored) |\n| Q3 | 4,310 | 4,440 | +3.0% | +3.0% (within range) |\n| Q4 | 4,440 | 4,600 | +3.6% | +3.6% (within range) |\n\nSum of capped/floored returns: 5.0% - 2.0% + 3.0% + 3.6% = +9.6%\n\nSince 9.6% > 0% (global floor), payoff = $1,000,000 x 9.6% = $96,000\n\nNote: The raw index return was (4,600/4,200 - 1) = 9.52%, so the cliquet actually outperformed the buy-and-hold due to the floor protecting against the Q2 drawdown while the cap only mildly reduced the Q1 gain.\n\nPricing Challenges:\n- Each sub-period is essentially an ATM forward-starting option\n- The local cap creates a short position in an OTM call per period\n- The local floor creates a long position in an OTM put per period\n- Skew and volatility smile significantly affect pricing (caps and floors are OTM strikes)\n- Correlation between periods matters for the global floor valuation\n- Monte Carlo simulation with stochastic volatility models (Heston, SABR) is standard\n\nWhy Structured Products Love Cliquets:\n- Principal protection via global floor appeals to retail investors\n- Periodic resets give a feeling of regular participation\n- Caps fund the floor, making the product self-financing for the issuer\n- The complexity makes the embedded margin opaque to end investors\n\nStudy structured product engineering in our FRM course.
