Leuthold Select Industries ETF (LST)

The Leuthold Select Industries ETF, trading as LST, represents a distinct bet on the power of timing and sector selection. Rather than holding a static mix of sectors or tracking a fixed index, LST rotates between industry groups — buying those showing momentum and valuation strength, selling or avoiding those showing weakness — in the belief that skilled tactical allocation can generate returns above a buy-and-hold benchmark.

“Sector rotation is not a way to time the market—it’s a way to tilt toward the sectors that are working now.”

That simple truth drives LST. Rather than assume the Technology sector will outperform Healthcare forever, or that Financials will remain depressed, the fund’s framework asks a blunter question: which industries show the best momentum, valuations, and technical strength right now, and how much capital should we commit to each?

How Leuthold selects and rotates industries

The Leuthold Group brings a long institutional history of systematic sector analysis to this fund. The selection process typically combines quantitative measures — relative strength, earnings yield, dividend yield, and momentum indicators — with a disciplined rebalancing calendar. Industries showing the strongest combination of these metrics get overweighted; those showing the weakest get underweighted or eliminated. The portfolio may hold all ten US sectors most of the time, but in dramatically different proportions, or it may tilt to a subset when the data strongly favors certain industries.

This is not stock-picking. LST does not attempt to identify which individual companies within an industry will win; it bets that an entire sector is entering a favorable period and allocates accordingly. That reduces complexity but introduces a different kind of risk: sector leadership patterns shift unpredictably, and a framework that works in one market regime can fail in another.

The bet and the uncertainty

Sector rotation as a persistent edge remains contested. Some research suggests that rotating between sectors based on valuation or momentum metrics generates excess returns after costs; other studies find the opposite — that the frictional costs of rebalancing outweigh any predictive power, or that apparent patterns vanish when tested on future data. LST exists because Leuthold’s team believes in the edge; investors in LST are, implicitly, making the same bet.

The fund’s volatility depends partly on how aggressively it tilts away from market-weight. A fund that holds Technology at 10% below the market weight and Energy at 10% above it will perform very differently in a technology bull market than the broad index would. In some years that difference favors the rotation strategy; in others it does not.

Costs and turnover

Because sector rotations happen regularly — sometimes monthly or quarterly — LST’s portfolio turnover is higher than a passive index fund’s would be. Higher turnover can trigger higher trading costs and, in taxable accounts, greater tax drag from capital gains realization. These frictions are real and cut into returns, which is why the fund’s expense ratio must be kept competitive enough to justify the active management cost.

Who LST is designed for

Sector rotation strategies appeal to investors who believe markets are not perfectly efficient at all times — that some industries enter periods of above-market attractiveness that can be identified in advance, and that disciplined rotation can capture that inefficiency. It also suits investors who want active management but prefer a mechanical, rules-based approach to discretionary stock-picking.

LST is less suitable for buy-and-hold investors seeking simplicity, or for those skeptical that sector timing can beat a low-cost broad index fund over the long run. The fund’s performance relative to the S&P 500 or a total-market index will wax and wane, and there will be multiyear stretches where passive indexing wins decisively.

Evaluating the fund

Start with the fund’s fact sheet and recent fact sheets from prior years. The Leuthold Group publishes clear descriptions of the metrics and thresholds that drive the rotation. Examine the historical sector weights — do they shift meaningfully over time, or has the fund gravitated toward holding the market weight for most sectors? Compare LST’s returns over rolling three-year and five-year periods versus the S&P 500 and a sector-rotation benchmark if one is published. A strategy that underperforms over most rolling periods, even when taking fees into account, suggests the rotation framework may not be capturing an exploitable edge.

Finally, assess your own conviction. If you believe sectors cycle in and out of favor in ways that can be predicted and monetized, and if you want that framework handled by a professional team rather than managing it yourself, LST offers a relatively liquid, low-cost way to gain that exposure. If you remain unconvinced that sector timing beats a static allocation or passive index, a simpler alternative is likely more cost-effective.
