The uncertainty around US tariff policy has significantly increased US equity volatility. Although Parametric had anticipated increased volatility in 2025, nobody knows where the market is headed next. In uncertain times like these, investors are justifiably looking for the tax benefits that loss harvesting can deliver.
Maximizing after-tax return is a key goal of direct indexing, but so is tracking the benchmark. Here’s why we think it would be a pyrrhic victory to let risk management suffer in pursuit of realized losses.
Balancing two objectives
Direct indexing has a dual mandate of seeking to provide pretax performance similar to the benchmark while aiming to outperform on an after-tax basis. We recognize that reaching for more losses can result in greater pretax return differences, yet managing risk too tightly can diminish the ability to capture losses.
To strike a balance between these competing goals, Parametric monitors portfolios daily with trigger-based loss harvesting and simultaneously employs risk controls every time a portfolio trades. At the end of the day, a direct index portfolio is a beta strategy, and clients are seeking index-like returns.
In pursuit of losses
A direct index strategy is often selected for the potential tax benefits it seeks to provide. We would argue that systematic loss harvesting and the resulting capital losses could be the silver lining to volatile periods such as the one we’re in. However, some investors may worry that their portfolio isn’t taking full advantage of the opportunities the market presents.
Over more than three decades of managing direct indexing portfolios, Parametric has been through multiple market cycles and volatile periods. Along the way, we’ve refined our approach to tax management with robust processes and ongoing research.
Parametric screens accounts for harvestable losses on a daily basis, capturing the tax benefit for clients by realizing losses while also managing risk. Given strong market returns over the past two years, even a more recently incepted portfolio may have experienced significant appreciation. Despite the US equity market decline year to date, losses in the portfolio may be limited.
Even if there are losses in portfolios, Parametric honors IRS wash sale restrictions whenever the account traded within the last 30 days.1 That decreases the eligible universe of securities we can buy and sell, while also helping to keep the portfolio well aligned to the benchmark.
Our goal is to harvest losses within a portfolio every time it makes sense to do so—both in and out of the wash sale period. But if we are overly aggressive in pursuit of losses, we may sacrifice risk management.
Consider the benefits of active tax management
Prudent risk management
Direct indexing portfolios are often the core equity holding for investors, and priority number one for Parametric is delivering a pretax return similar to the index. However, active tax management tends to result in a portfolio that looks a bit different than the benchmark it tracks: Selling to realize losses results in stock-specific underweights, and those biases increase the risk that the portfolio will deviate from the benchmark on a pretax basis.
To help control risk, we try to limit how much a portfolio can differ from its benchmark by managing both systematic factors—such as industry membership or equity style—and stock-specific risk. Our investment process manages stock-specific risk in two primary ways:
1. Limiting how far we’ll sell down a position to realize a loss
For the larger constituents of an index—such as the Mag 7 stocks—it would be risky to completely sell out of a position to capture the losses. If an investor wants to be more aggressive, we can accommodate them by relaxing that limit and allowing higher risk.
2. Requiring deeper losses to sell more volatile stocks
We differentiate stocks based on riskiness because we recognize that riskier stocks may be more likely to contribute to pretax return differences. With that in mind, we generally look for deeper losses whenever we consider harvesting losses in a highly volatile stock, and we try to reduce preexisting underweights whenever we can.
Why managing stock-specific risk is so important
Here’s an example of how active tax management can introduce stock-specific risk into a direct index portfolio. A large decline in a single stock makes it a good candidate to sell for loss harvesting, but that could also make the portfolio underweight the stock relative to the benchmark. If the stock subsequently outperforms the benchmark, then the portfolio’s pretax return would suffer.
Much of the time, single-stock underweights and overweights have tended to cancel each other out. But in a volatile period, or when an underweight stock’s performance is exceptional, it could create a meaningful drag on pretax return. This is exactly what happened to a handful of large index names in the recent past, and that’s why Parametric’s approach seeks to fine-tune risk management for highly volatile stocks.
The bottom line
Like an army whose victory in battle inflicts such a devastating toll on its own troops that it ends up losing the war, pursuing losses without regard for risk would be a pyrrhic victory. With more than three decades of experience in active tax management, Parametric has spent a lot of time thinking about the trade-off between delivering losses and managing risk. Our stance is that it’s better to take a balanced approach, especially in volatile markets.
1 In a wash sale, the same security sold for a loss is purchased 30 days before or after the sale. If a transaction violates the rule against wash sales, the IRS can disallow the loss deduction and add the loss to the cost basis of the repurchased security, which can effectively defer the benefit of the loss.
