Event-driven strategies concern situations in which the underlying investment opportunity and risk are associated with an event. An event-driven investment strategy finds investment opportunities in corporate transactional events such as consolidations, acquisitions, recapitalizations, bankruptcies, and liquidations. Managers employing such a strategy capitalize on valuation inconsistencies in the market before or after such events, and take a position based on the predicted movement of the security or securities in question. Large institutional investors such as hedge funds are more likely to pursue event-driven investing strategies than traditional equity investors because they have the expertise and resources to analyze corporate transactional events for investment opportunities.
Corporate transactional events generally fit into three categories: distressed securities, risk arbitrage, and special situations. Distressed securities include such events as restructurings, recapitalizations, and bankruptcies. A distressed securities investment strategy involves investing in the bonds or loans of companies facing bankruptcy or severe financial distress, when these bonds or loans are being traded at a discount to their value. Hedge fund managers pursuing the distressed debt investment strategy aim to capitalize on depressed bond prices. Hedge funds purchasing distressed debt may prevent those companies from going bankrupt, as such an acquisition deters foreclosure by banks. While event-driven investing in general tends to thrive during a bull market, distressed investing works best during a bear market.
Risk arbitrage or merger arbitrage includes such events as mergers, acquisitions, liquidations, and hostile takeovers. Risk arbitrage typically involves buying and selling the stocks of two or more merging companies to take advantage of market discrepancies between acquisition price and stock price. The risk element arises from the possibility that the merger or acquisition will not go ahead as planned; hedge fund managers will use research and analysis to determine if the event will take place.
Special situations are events that impact the value of a company's stock, including the restructuring of a company or corporate transactions including spin-offs, share-buy-backs, security issuance/repurchase, asset sales, or other catalyst-oriented situations. To take advantage of special situations the hedge fund manager must identify an upcoming event that will increase or decrease the value of the company's equity and equity-related instruments.
Other event-driven strategies include: credit arbitrage strategies, which focus on corporate fixed income securities; an activist strategy, where the fund takes large positions in companies and uses the ownership to participate in the management; a strategy based on predicting the final approval of new pharmaceutical drugs; and legal catalyst strategy, which specializes in companies involved in major lawsuits.
