Nathaniel Beaumont Vasquez , CFA, MSF

Nathaniel manages concentrated-position portfolios for post-IPO employees whose single-stock holdings run 60% to 90% of investable net worth. A typical new client shows up with $8M to $40M in one ticker, vested but held, and a desire to diversify without writing a $2M tax check in a single year. He does not believe in single-solution answers for these clients. Most end up with a layered approach that combines scheduled sales under a 10b5-1, an exchange fund for a portion of the legacy basis, and a direct-indexed completion portfolio that harvests losses to absorb realized gains.

The scenario he works through weekly is the exchange-fund opportunity cost. A VP has $12M in a single post-IPO stock, cost basis of $400k. Selling outright realizes $11.6M of long-term gain, $2.76M of federal plus California capital-gains tax at 33.3% combined. Contributing to a seven-year exchange fund defers the entire gain, but the client locks up the shares for 84 months, cannot sell during a potential drawdown, and pays roughly 90 to 140 basis points in annual fees on assets that were previously held free. Nathaniel models the break-even against scheduled sales with loss-harvested offsets, and for clients under age 55 with healthy income he usually recommends against the exchange fund.
