Keep tax-loss harvesting working in any market.

Add a controlled short allocation to any direct index, up to 200/100, and harvest losses in rising and falling markets while staying close to your benchmark.

Onboard in as little as 1 week

Long-only harvesting has a shelf life.

Long-only portfolios run low on losses as they appreciate, and the harvesting benefit fades over time.

Forcing new losses out of a long-only portfolio can mean more turnover or a wider gap from the benchmark.

Long/short has traditionally been the domain of hedge funds and institutions, which often means handing the strategy to someone else to run.

Alphathena adds a controlled short allocation and keeps your exposure similar to your benchmark.

Pairing long and short positions expands the set of losses available to harvest without materially changing the risk of the portfolio. With the Alphathena platform, you are in control of every decision and every trade.

Institutional-grade long/short, with the controls advisors need.

Choose your structure

Any leverage combination, up to 200/100.

Build the structure that fits each client, from a light 110/10 tilt to the popular 130/30 and 150/50, all the way up to 200/100.

Benchmark and factor control

Stay aligned with your benchmark.

Choose your benchmark, set a tracking error limit and tight beta band, and add a factor or theme tilt when a client wants one.

Losses on both sides

Harvest losses from the long book and the short book.

Short positions can produce losses when markets rise, and long positions can produce them when markets fall, which widens the opportunity to harvest in any market. Wash sale rules are built into the optimization with a 30-day look-back on every sold position.

Know costs upfront

Borrow, financing, and trading costs are part of the optimization.

Every short candidate is checked for borrow availability, and financing, borrow, and transaction costs are modeled alongside the tax impact.

Custodian flexibility

Available at Schwab, Fidelity, or Interactive Brokers.

Long/short works with margin accounts at all three, so the custodian decision stays with you and your client. Preferred pricing is available through Interactive Brokers.

You set the strategy. Alphathena's agentic platform helps you run it.

No third-party managers or handoffs.

Your strategy

Set the leverage, benchmark, and tilts for each client, inside the same platform you already use for direct indexing and tax-loss harvesting.

One platform

Long/short sits beside tax-loss harvesting, transition analysis, workflow automation, and Athena AI, so there is no second system to learn or reconcile.

Run long/short for your clients, in-house.
