Four times a year, I spend several hours looking through Form 13F filings from the hedge funds that specialize in merger arbitrage. I document and analyze which merger stocks the funds have bought and which ones they haven't. I then compile the top 10 stocks held in these funds and share it with our Seeking Alpha community.

My rules:

  • I only count a stock if it is at least 1% of the fund's portfolio.
  • I only include stocks that are still actively trading.
  • I only choose funds where the vast majority of the positions are merger-related.

The Top Two

Cerner Corporation (CERN) is the top stock appearing in 26 of the 31 funds. Oracle (ORCL) is in the process of buying Cerner for $28.3 billion which works out to $95 in cash. The merger is structured as a tender offer and it expires June 6 though it can be extended if all regulatory approvals aren't satisfied. Cerner is a leader in the field of software and information systems used in hospitals and healthcare systems. The deal has cleared HSR but still needs EU approval. European regulators have set a provisional deadline of June 1. Cerner's stock has been super strong in the recent ugly tape.

Zynga (ZNGA) is in 19 of the funds. The videogame company is being bought by the larger Take-Two Interactive (TTWO) in a cash and stock deal. Upon closing, Zynga shareholders will receive $3.50 plus .0406 TTWO shares. Potential antitrust issues were possible in delaying the merger but HSR expired in February. All that remains is the shareholder vote on Thursday with closing expected after trading the following day.

Top 10 Merger Arb Stocks Held By Funds

1) Cerner Held by 26 funds 9% IRR
2) Zynga Held by 19 funds 32% IRR
3) Activision Blizzard (ATVI) Held by 18 funds 24% IRR
4) Anaplan (PLAN) Held by 18 funds 22% IRR
5) Coherent (COHR) Held by 17 funds 31% IRR
6) Nielsen (NLSN) Held by 16 funds 33% IRR
7) Vonage (VG) Held by 15 funds 88% IRR
8) Citrix Systems (CTXS) Held by 14 funds 29% IRR
9) First Horizon Corp (FHN) Held by 12 funds 20% IRR
10) CMC Materials (CCMP) Held by 12 funds 12% IRR

When a fund makes an M&A stock its number one holding, it signals strong conviction that the deal will ultimately close. Nine funds had Cerner as its top pick as of the end of the first quarter.

While there is no substitute for doing one's own work and developing one's unique trading/investing style, looking at what some of the top arb hedge funds are doing with their money is quite valuable. These funds have more resources, staff, and contacts that an individual investor can possibly have.

While there is no guarantee that the above deals will close, the fact is more than 90 percent of all mergers do close and when the specialists allocate their money to an arb position the odds even get better.
