A secondary investment means buying an existing investor's stake in a private equity fund, rather than committing fresh capital to a new fund at its launch (a "primary" commitment). It is one of the more overlooked ways to access private equity, and it changes the risk profile in specific, useful ways.

Why secondaries exist

Private equity fund commitments typically run for around a decade, but an investor's circumstances can change well before that: an institution may need to rebalance, an individual may need liquidity, or a fund-of-funds may simply be restructuring its holdings. Rather than being stuck, LPs can sell their existing fund stake to another investor on the secondary market — the closest thing private equity has to an exit ramp before a fund's natural end.

The genuine advantages

  • Reduced blind-pool risk — because the fund has already deployed some or most of its capital, a buyer can review the actual portfolio companies rather than committing to an unknown future selection.
  • Shorter effective holding period — buying into a fund partway through its life generally means a shorter remaining term to exit than a primary commitment into a brand-new fund.
  • Reduced J-curve effect — since the fund's early fee-drag years are already behind it, a secondary buyer often avoids the steepest part of the typical J-curve pattern described in Private Equity Investment Funds Explained.
  • Potential discount to NAV — secondary stakes are sometimes available below the fund's reported net asset value, though this varies considerably by fund quality, vintage and market conditions, and is never guaranteed.

The trade-offs

  • Valuation complexity — pricing a secondary stake requires assessing an existing, partially realised portfolio, which is more specialised than evaluating a fund's stated strategy alone.
  • Still illiquid — a secondary purchase does not create ongoing liquidity; you are still locked in until the fund itself winds down or you sell again.
  • Access is specialised — direct secondary purchases are typically the domain of dedicated secondary funds and institutional buyers, given the specialist valuation work involved.

How UK retail investors actually get exposure

Direct secondary purchases of individual LP stakes are generally not practical for retail investors. The realistic route is via listed vehicles that specialise in or regularly conduct secondary transactions as part of their strategy — some private equity investment trusts do this alongside primary fund commitments and co-investments. See Private Equity Investment Trusts Explained for how that listed, FCA-regulated route works, including the premium/discount-to-NAV dynamic that applies there too.

Before considering secondaries exposure

  • Check whether a trust or fund's stated strategy actually includes secondary purchases, and what proportion of its portfolio that represents.
  • Understand that a "discount to NAV" on a secondary stake and a trust's own share-price discount to its NAV are related but distinct concepts — don't conflate them.
  • Ask how the manager values existing fund stakes, and how independent that valuation process is.
