Convertible arbitrage and short exposure
* Note: this is a backdated post from something I took notes on in the past. Further disclaimer: Some of my ex-colleagues worked on this deal
During my time in banking, there was one particular deal that fascinated me due to its cleverness: GoPro’s convertible issuance in 2017 April . Matt Levine writes about it here, my summary is below:
-
If your company is doing badly, it can be hard to get debt or issue equity
-
A convertible note might be a great option since convertible arbitrage investors (Arbs) want volatility. Your stock price decline has probably created significant volatility
-
Arbs go long the convertible, and short the stock to hedge the equity exposure
-
But your company probably has a lot of short sellers already. This can make short selling expensive
-
If shorting is expensive, Arbs won’t want to play, and you won’t get enough investor interest
-
The solution is to let Arbs short the stock to the company (rather than on the market) through derivatives
- The bank underwriting the convert sells your stock to you in a forward contract for future delivery
- You give the bank money now, the bank gives you stock in the future
- The bank is effectively short your stock
- The bank doesn’t want the short exposure, so it does an offsetting swap with arbs, letting them get the exposure without borrowing the stock on the market
- Arbs get cheap short exposure to hedge the convert, making it easier to buy the convert
- The bank underwriting the convert sells your stock to you in a forward contract for future delivery
-
The downside is you spend money on the forward contract buying back stock, so you don’t get the full convertible raise
- Which makes this popular for companies that want to buy back stock and don’t really need cash
-
The company is effectively selling a convertible and buying back the stock price risk, leaving investors with volatility risk
