SPY Holy Grail v1: One Year Live

Does it actually work in real life?

This is the question I get more than any other. The backtest looks great, sure. But does the strategy hold up when it has to trade through real conditions?

Today I have a real answer. Not a simulation, not curve-fitting. Fourteen months of live forward-tested results on the SPY Holy Grail v1, including a genuine market shock (the April 2025 tariff sell-off) and a full mix of conditions on either side of it.

Short version: 32.76% CAGR vs SPY buy and hold's 20.19%, with less than half the drawdown.

Before we start

Nothing in this article is financial advice. It's all for education. Past performance, even live forward-test performance, doesn't guarantee future results.

The forward window runs from 3 March 2025 to 28 April 2026, and reflects live application of a strategy that was designed, locked in, and published before that window started.

What the Holy Grail actually is

Holy Grail v1 isn't one strategy. It's five, all trading the same instrument (SPY), all with different personalities and different triggers:

• Volume Revertor

• Dip Server

• Wave Chaser

• EMA Cross

• RSI Cross

Because the five can hold positions at the same time, combined exposure often goes above 100%. Average exposure over the live window came in around 119%, basically a small touch of leverage.

The benchmark is the simplest thing imaginable: buy SPY, hold SPY, reinvest dividends. Same instrument, no timing. The question is whether being smarter about when we own SPY beats just owning it.

The metrics

CAGR is your average speed on a road trip. The consistent annual growth rate that would have taken you from start to finish.

Max drawdown is the deepest valley on the hike. SPY's worst drop was more than double the Holy Grail's.

MAR ratio is CAGR divided by max drawdown. It tells you how much return you got per unit of pain. 4.30 vs 1.23 means the Holy Grail delivered about 3.5 times more return per percent of drawdown.

Sharpe and Sortino measure the smoothness of the ride. Sortino only penalizes downside swings. Both came in meaningfully better.

Ulcer Index combines depth and duration of drawdowns. Lower is better. Holy Grail wins here too.

The equity curve

Starting with $100,000 on 3 March 2025:

• SPY buy and hold ended at $121,038 (+21.0%)

• Holy Grail ended at $139,098 (+39.1%)

That's an extra ~$18,000 on a $100,000 account in just over a year. And as the chart shows, the Holy Grail line stayed above SPY almost the entire time, with shallower dips along the way.

The drawdown profile

Here's what "less than half the drawdown" looks like in picture form. The April 2025 spike is unmistakable on the SPY curve, and conspicuously absent on the Holy Grail's.

The April 2025 tariff shock

This is the part I care about most. Backtests don't have surprise headlines. Live trading does.

• April 2 to 4, 2025: tariff announcements trigger a sharp sell-off. SPY drops from about $95k account value to about $85k in three days.

• April 7 to 8: SPY troughs at -16.46% from peak.

• The Holy Grail's worst point in the same window: -7.62%.

• April 9: a 90-day tariff pause is announced. SPY gaps up hard. Holy Grail was already positioned to participate.

• April 22 to 28: Holy Grail is back above its 3 March starting equity (+0.05%). SPY is still -7.3% from where it started.

This isn't a market timing crystal ball. No strategy reliably predicts macro shocks. But the rules that govern entries and exits happen to create a natural buffer when conditions like this hit: short holding periods, rules-based exits, and exposure that backs off when setups stop firing.

That's the real-world value of a strategy like this.

Risk vs return in one picture

I like this chart because it collapses the whole decision into one image.

• X-axis: max drawdown (lower is better, so further left)

• Y-axis: CAGR (higher is better, so further up)

• Upper left is where you want to live: more return, less pain.

SPY sits at lower right. Holy Grail sits up and to the left. Visually it isn't close.

The trade statistics

Strategy becomes concrete at the trade level. Over 14 months the five sub-strategies executed 48 combined trades, roughly three to four a month. Not hyperactive. Not asleep.

• Win rate: 77.1% (37 winners / 11 losers)

• Profit factor: 3.96 ($3.96 made for every $1 lost)

• Average win: +1.84% · Average loss: -2.05%

• Expectancy: +0.95% per trade

• Average winner held ~11.4 days. Average loser held ~5.7 days, so losers get cut about twice as fast as winners are allowed to run.

A 77% win rate alone wouldn't be enough on its own. You could win 90% of the time and still lose money if your losers were huge. The expectancy is what ties everything together: about 1% per trade, compounded across 48 trades.

The monthly scorecard

Averages hide a lot. Month by month:

• Holy Grail had 9 of 14 positive months. SPY had 10 of 14.

• So SPY actually won more individual months. But look at which months.

• March 2025: roughly even (HG -6.34% vs SPY -5.57%).

• April 2025 (the shock): HG +4.48% vs SPY -0.87%. The standout.

• May to October 2025: Holy Grail beat SPY in 5 of 6.

• November to December 2025 (quieter tape): SPY edged ahead.

• April 2026: SPY rallied +9.43%. Holy Grail +6.23%. Solid month, just not as strong as a clean straight-up rally.

• Average monthly: HG +2.07% vs SPY +1.47%.

Holy Grail earns its keep in volatile, mean-reverting conditions. It doesn't claim to beat SPY in a quiet melt-up, and that's fine.

33 years of context

The same five rules run back to 1993, with the live portion shown in amber so you can see where backtest ends and reality begins.

Starting from $100,000 in January 1993:

• SPY buy and hold → $2.94M. 10.69% CAGR. Max drawdown -55.2% (2008 to 2009).

• Holy Grail → $106.5M. 23.35% CAGR. Max drawdown -23.4%. About 36 times SPY's terminal multiple.

Those numbers deserve your skepticism, not just your excitement. Backtests are built on historical data, and markets evolve. There's no guarantee the same edge persists forever.

What I can say: the strategy was locked in before the live window started, and the live behavior matches the long-run character. Higher return, lower drawdown, better risk-adjusted metrics. That consistency is meaningful evidence. It isn't proof of the future, but it's the kind of real-world validation you actually want to see.

Bringing it together

Fourteen months of live forward-tested results, including a real tariff-driven crash:

• 32.76% CAGR vs SPY's 20.19%

• -7.62% max drawdown vs SPY's -16.46%

• MAR 4.30, more than 3x SPY's 1.23

• 77.1% win rate, 3.96 profit factor

• 0.91 R² equity curve linearity

This isn't a get-rich-quick story. It's about compounding better, risking less, and sleeping at night, while owning the most liquid and most followed instrument in the world.

Fourteen months is short. We need more data and more cycles. But the April 2025 shock test is the kind of live, unforecastable evidence that builds genuine confidence. The strategy did what it was designed to do. Protect on the downside, stay engaged on the upside.
