A series of large and bad personal investments can wipe out most of us. Think crypto currencies, structured products, peer-to-peer lending, and most angel investment opportunities. So, how can we avoid poor investment opportunities? There are several similarities between personal investing and private equity (PE) funds, which invest in unlisted mid-sized companies. PE investing techniques can provide some useful lessons.
Both personal investing and PE investing force one to accept relatively concentrated portfolios, deal with significant information asymmetry, and make medium-term decisions that are difficult to reverse. Mutual fund managers, on the other hand, can have relatively diversified portfolios. Listed companies are required to provide information uniformly to all investors. And most decisions are easily reversible.
Concentration risk: For the sake of brevity, let’s consider only the first similarity, that is, concentrated portfolio. Due to an individual’s limited net worth and finite mental bandwidth, he can invest in only a limited number of asset and sub-asset classes, such as domestic equities, international equities, residential real estate, gold, debt mutual funds, and a few bonds and deposits. Hence, a significant portion of a person’s net worth is invested in each of them.
Unlike an early-stage venture capital fund, a mid-sized PE fund will have just 10-15 investments. If a couple of them get wiped out, the fund will underperform. Most mutual fund asset management companies (AMCs), on the other hand, have a large number of funds, possibly to hedge their track record and reputation. Each of the funds invests in 25 stocks or more, so no single investment is critical to the AMC.
The lessons that some competent PE investors have used to minimise their risks can be applied to personal investing as well. Here are seven of the most important questions they ask when evaluating an investment.
