Lock-in investment refers to the investment that has a lock-up period and cannot be freely traded or cashed out. This type of investment usually comes with illiquidity risk and asymmetric risk-return profile. Many private equity funds, venture capital funds, hedge fund investments, and pre-IPO shares have lock-in periods for investors. When considering a lock-in investment, it is crucial for investors to assess the liquidity risk, evaluate if the higher expected returns justify the liquidity sacrifice, and manage the asymmetric risk properly.

Understand the liquidity risks of lock-in investments
The lack of liquidity means investors cannot access their money before a certain period. This could be problematic if investors face unexpected cash needs. Before committing capital into an illiquid asset, investors should evaluate their cash flow needs carefully and keep proper emergency reserves. It is also important to diversity the lock-in investments across vintages, sectors, and managers to minimize liquidity crunches.
Evaluate if expected returns compensate for liquidity risks
The returns of private equity funds and venture capital funds are higher compared to public market investments, mainly due to the illiquidity premium. Investors should compare the net returns with public market equivalents based on proper benchmarks. The valuation updates of lock-in investments could also justify some interim performance judgments before realizing the gains.
Manage asymmetric risks in lock-in investments
The asymmetric risk means the downside risk is much greater than the upside potential in lock-in investments. If the project fails during the lock-up period, investors could face steep losses without exits. Proper portfolio construction across assets, continuously tracking milestone progress, and seeking co-investment opportunities could help investors manage such asymmetric risks.
In summary, lock-in investment comes with liquidity sacrifices and asymmetric risk-return profiles. Investors should assess their liquidity needs, evaluate if premium compensates for liquidity risks, and manage the downside risks properly through portfolio diversification as well as progress tracking.
