Regents Park Hedged Market Strategy ETF (RPHS)

The Regents Park Hedged Market Strategy ETF (RPHS) emerged from a straightforward question: what if you could own the stock market’s gains but cap its losses? The fund combines a core portfolio of large-cap U.S. stocks with a systematic program of protective options — put options, chiefly — to guard against large drawdowns. Over its years of operation, RPHS has evolved from a niche product aimed at wealthy advisors seeking downside cushioning into a more mainstream tool for any investor unsettled by equity volatility but unwilling to abandon stocks entirely. The fund represents a trade: accept modestly lower returns in calm markets in exchange for meaningfully smaller losses when the market stumbles.

The founding insight

RPHS was designed to address a chronic frustration with stock investing: the asymmetry of emotion. Investors feel each 5% decline acutely but often discount steady 2% annual gains. A protective collar — long stocks, short calls, long puts — had been used by wealthy individuals and institutions for decades, but implementing it at scale, transparently, and cheaply enough for retail portfolios was difficult. Traditional options programs were expensive, illiquid, and ate most of the upside through premium costs. The fund was structured to layer protective puts atop a broad-market equity core and manage the cost by selling some upside — a covered call overlay — to partially fund the insurance. The result is not a 1-to-1 replication of pure equity returns, but it is equity-like with a visible floor.

How the hedge actually works

The fund holds a large portion of its assets in a broadly diversified portfolio of large-cap U.S. equities, typically tracking an S&P 500-like composition. Alongside those stocks, it purchases put options that grant the right to sell the underlying index at a pre-set strike price — typically around 15% below the market at the time of purchase. These puts act as insurance: if the market falls 20%, the put loses only the amount below the 15% threshold, while the investor’s direct equity loss is cushioned. To defray the cost of this insurance, the fund sells call options against the stock portion, meaning it surrenders some of the upside if the market rallies strongly. The net effect is a “band” — losses below a certain floor are mitigated, but gains above a certain ceiling are forgone.

The trade-off in practice

In calm or rising markets, the call premium the fund receives helps offset the cost of the puts, and the drag is modest. An investor in RPHS might trail a pure S&P 500 fund by 1–2 percentage points annually during a bull market, a cost that feels reasonable in exchange for peace of mind. In severe down markets — a 30% or 40% crash — the protective puts shine. A 30% market drop might clip RPHS by only 15–18%, a gain relative to an unhedged portfolio that can be measured in years of recovery time saved.

The hidden cost comes in the strategy’s rigidity. The puts are rebalanced periodically, meaning that as the market falls and the floor protection has been partially used up, the fund buys new puts at lower prices. If the market stabilises before the floor is fully breached, the fund has paid for insurance that never paid off. Conversely, if the market rallies strongly, the sold calls lock in lower returns permanently. The hedge is not free and is not free across all market conditions.

Evolution and acceptance

When RPHS launched, similar protective-collar funds were viewed as oddities — the province of risk-averse retirees or investors scarred by past crashes. Over time, as financial advisors incorporated behavioural science into portfolio design, the funds gained respectability. The insight that investors who panic and sell at market bottoms suffer permanent damage to their wealth eventually outweighs the modest long-term drag of options costs. A fund that lets an investor stay put in a crash is worth the insurance premium, even if the math suggests pure equities would have been better in hindsight.

The fund has since expanded in assets under management, supported by steady flows from advisors who recommend it to clients seeking simplicity — a single holding that delivers equity-like exposure with a built-in shock absorber. The fund publishes its current protection level (the floor), so investors can see at any moment how much downside is covered.

Liquidity and suitability

RPHS trades as a transparent exchange-traded fund with reasonable daily volume and tight spreads. It is suitable for long-term buy-and-hold investors, retirement portfolios, and anyone for whom selling in a panic has been a historical problem. The fund is less suitable for traders or anyone betting on a sharp, quick recovery from a crash — the hedge is designed to reduce losses, not to amplify gains when the market rebounds.

How to research RPHS

Start by reviewing the fund’s prospectus and the quarterly fact sheets, which detail the current protective put strikes and the call-sale levels. Calculate the “protected range” — the floor and ceiling of the band — and decide if that risk/return trade-off fits your own goals. Look at the fund’s rolling returns across different market regimes: calm-market years, strong bull markets, and bear markets. Compare those returns to a pure S&P 500 fund to quantify your insurance cost. Watch the expense ratio and the embedded options costs, which fluctuate based on volatility. Finally, ask yourself an honest question: am I buying this because I need help staying the course, or because I believe options magic will let me have equity returns without equity drawdowns? The first motivation is sound; the second is naive.
