Rayliant SMDAM Japan Equity ETF (RAYJ)

RAYJ gives investors a way to own Japanese stocks. Japan’s stock market is huge. It has many world-class companies — Toyota, Sony, Uniqlo, Nintendo, and hundreds of others that are unknown to most Western investors. But Japan’s market moves differently than U.S. stocks. Companies have different ownership structures. Accounting rules differ. Valuations don’t move the same way. For an American or European investor, picking Japanese stocks directly is hard because you need to understand how Japanese business works.

RAYJ solves this by using a machine-learning model to pick Japanese large and mid-cap stocks that score well on fundamental quality measures — earnings stability, return on invested capital, accounting cleanliness — and also trade at reasonable valuations. The fund holds thirty to fifty stocks, not a hundred, so it’s concentrated enough to matter but diversified enough to avoid disaster if one company stumbles.

How the Rayliant system works

Rayliant, the index provider, builds models that look at accounting data and price history. The models identify stocks that historically make good long-term returns — companies that earn real profits, grow consistently, and don’t blow up in recessions. The SMDAM (Strategic Momentum Dividend Anomaly Management) model adds a layer: it screens for a combination of profitability, value, and momentum. In other words, it favors companies that are fundamentally sound, cheap, and currently performing well relative to their history. This is not day-trading. It’s saying: “Good companies that trade at fair prices tend to outperform.”

For Japan specifically, this approach has appeal. Japanese companies are often richly profitable and stable but trade at moderate valuations because the stock market has been unpopular with global investors for decades. A model that identifies cheap, profitable Japanese stocks finds real opportunities that a simple market-cap index would miss.

What you own when you buy RAYJ

The fund typically holds thirty to fifty Japanese large-cap and mid-cap stocks, selected by the quantitative model. You get exposure to familiar names — banking, automotive, electronics, chemicals — and some smaller titans that trade at modest multiples of earnings. Because the model screens out weak companies and overvalued ones, the portfolio tends to be more profitable and slower-growing than the Japanese stock market overall. You own mature, cash-generative businesses rather than moonshots.

The portfolio tilts toward value and dividends, because those are the characteristics the model favors. Japanese companies have a long tradition of paying dividends and returning cash to shareholders, so this tilt aligns with the fundamental character of the market. Concentration is moderate — the largest holding typically represents five to eight percent of the fund, so there’s real diversification but not false diversification.

Currency and exchange-rate risk

RAYJ is not hedged for currency. If you are an American investor, you own Japanese stocks, and the yen’s movement against the dollar matters. When the yen strengthens, Japanese stocks become more valuable in dollar terms, and you benefit. When the yen weakens, you lose ground in dollar terms even if the stocks themselves rise in yen. Over decades, this currency effect is manageable, but over short time horizons it can swing returns substantially. This is true for any Japan-focused fund and is one reason Japan exposure is suitable only for investors with a long time horizon and comfort with currency volatility.

Costs and why RAYJ is not the only Japan ETF

RAYJ’s expense ratio covers the cost of building and maintaining the quantitative model, plus the standard costs of portfolio management and trading. It is not the cheapest way to get Japan exposure — a plain market-cap–weighted Japan index ETF costs less. But RAYJ’s quantitative selection is meant to add value by avoiding bad companies and finding reasonably priced good ones, which a simple market-cap index cannot do.

Japan offers many ETF options: broad index funds, dividend-focused funds, smaller-cap funds, sector-specific funds, and leveraged and inverse products that don’t belong in a buy-and-hold portfolio. RAYJ’s niche is disciplined large and mid-cap selection via quantitative factors. If you want to own Japan and you believe that fundamental quality and valuation discipline beat a simple index, RAYJ fits. If you want the broadest, cheapest Japan exposure, a market-cap–weighted Japan ETF is the right answer.

The Japan market and the Japan premium

Why own Japan at all? For decades, Japan was a neglected market by global investors. After the bubble burst in 1990, the economy stagnated for years, and investors simply stopped paying attention. Yet Japanese companies kept making money. They paid dividends. They returned cash to shareholders. But valuations stayed low because demand was low. In recent years this has changed somewhat — more investors have recognized that Japan is not permanently broken — but the market still trades at lower multiples than U.S. or European peers, creating what some call the Japan premium: a group of profitable, productive companies that trade as though the country is still stagnant.

RAYJ is a bet that this valuation discount eventually narrows. It is not a bet on growth. It is a bet that you can buy good companies at fair prices in a market where other investors have been indifferent for a generation, and that eventually someone else will realize the value. Over long time horizons and with patience, that has been a productive bet in Japan before.

Evaluating RAYJ

Anyone considering RAYJ should read Rayliant’s fact sheet to understand the specific factors the SMDAM model screens for and to see the current holdings. Compare the fund’s performance to the unhedged Japan market index over different time horizons — you should see that RAYJ’s quantitative selection adds value most of the time, though there will be periods (like strong growth rallies in unprofitable technology) when the model lags. Check the fund’s trading volume and expense ratio against alternatives. Most importantly, ask yourself: do you believe in quantitative selection, do you have a long time horizon, and are you comfortable with currency risk? If the answer to all three is yes, RAYJ is worth the consideration.
