famous stock pairs to trade backtest — KO/PEP, MA/V, TGT/WMT losses vs HGV/MGM winnerFive-year backtest, identical settings: the three textbook pairs all lost; HGV/MGM went nine for nine.

I ran all three through a five-year backtest last week. Every one of them lost money.

This isn’t a trick. Same settings for every test, disclosed in full below, straight out of our software. And the punchline isn’t that pairs trading doesn’t work.

Pairs Trading Example: The Vegas Pair That Kept Paying for 5 Years

September 13, 2026 1:35 pm |

Want a real pairs trading example instead of theory? Here’s one straight from our platform: Hilton Grand Vacations (HGV) and MGM Resorts (MGM). Two Las Vegas-rooted leisure stocks. One quietly reliable trading relationship.

The numbers: 12 trades, 12 winners

We ran a 5-year end-of-day backtest at $5,000 per leg. The results speak plainly:

  • 12 completed trades — every one profitable
  • Net profit: $3,122 after $258 in commissions
  • Average profit per trade: $260
  • Maximum drawdown: just 4.02%

The equity curve is a staircase, not a rollercoaster.

market-neutral pair trading

Most retail trading strategies depend on direction — and direction is the one thing nobody can predict consistently. By contrast, market-neutral pair trading offers an alternative: trades constructed not on whether a market rises or falls, but on the relationship between two fundamentally related assets. As a result, when that relationship temporarily diverges, mean reversion offers a measurable, repeatable edge.

Your Shortcut to Market-Neutral Pair Trading Success

This May, after another quarter of research, recalibration, and statistical validation, we are releasing the May 2026 Vintage of our Top 50 USA Stock Pair Stars.

Faster Reversion = Better Profits in PairTrade Finder® UA3

One of the biggest hidden risks in pair trading isn’t finding a cointegrated relationship. It’s trading a pair that reverts too slowly to be profitable before costs, time decay, or market drift eat your edge.

That’s exactly why we’re adding the OU Half-Life Filter to PairTrade Finder® Ultimate Alpha 3. It’s a simple, powerful new layer that tells you how fast a spread will snap back — so you only trade the pairs that can actually make money in real-market conditions.

Why We Keep It Simple (On Purpose) Kalman filters

It’s a fair question. Kalman filters are widely used in quantitative finance and are often presented as a more advanced way to trade pairs.

So this post explains our thinking clearly.

PairTrade Finder® is designed to capture most of the statistical edge—without the complexity that often reduces real-world performance.

In practice, as a rule we seek to target a platform that delivers 80% of the benefit of institutional grade models with around 20% of the complexity.
