Concentrated Stock Diversification

Enhanced Direct Indexing

Diversify a concentrated stock position while harvesting tax losses to offset capital gains. Direct indexing replaces the index fund with individual stocks, generating systematic losses that can offset the gains from selling your concentrated position.

Model Your Unwind

How EDI Works

A systematic approach to unwinding a concentrated position while minimizing the tax cost.

1

Sell & Realize Gains

Gradually sell the concentrated stock over your chosen unwind period. Each sale realizes long-term capital gains on the embedded appreciation — the tax you're trying to offset.

2

Build a Direct Index

Reinvest proceeds into a direct index portfolio — individual stocks tracking the S&P 500. Unlike an ETF, owning individual names means you can sell losers while keeping your market exposure.

3

Harvest & Offset

Systematically harvest tax losses from the direct index to offset the gains from selling concentrated stock. Beta and leverage amplify both the exposure and the loss harvesting opportunity.

Why Direct Indexing?

Investment Alpha with Tax Benefits

Harvest 2–4% of portfolio value in tax losses annually, especially in the early years.

Beta Matching

Match the risk profile of your concentrated stock by adjusting the beta exposure.

Loss Carry-Forward

Unused losses carry forward indefinitely, offsetting future gains and up to $3K/year of ordinary income.

Leverage Amplification

Modest leverage increases both market exposure and the pool of stocks available for loss harvesting.
