NEW YORK (Business Wire) -- UBS Investment Bank announced that today is the first day of trading on the NYSE Arca for the following two new ETRACS Exchange Traded Notes (“ETNs”) linked to the daily performance of The Fisher-Gartman Risk Index (the “Index”):

				ETRACS Fisher-Gartman Risk On ETN (the “Risk On ETN”)
				Ticker: ONN
				ETRACS Fisher-Gartman Risk Off ETN (the “Risk Off ETN”)
				Ticker: OFF

Investors now have the ability to implement comprehensive “risk on” and “risk off” trades through the purchase of these new exchange-traded securities, ONN and OFF, respectively.

The Risk On ETN provides investors with the ability to implement a comprehensive “risk on” trade through the purchase of a single, exchange-traded security, ONN. The Risk On ETN provides long exposure to the daily performance of The Fisher-Gartman Risk Index (the “Index”). As such, investors gain exposure to an index comprised of long positions in “risk on” instruments and short positions in “risk off” instruments linked to commodities, equities, currencies and sovereign bonds. The Risk On ETN's value is expected to rise when the outlook on markets and the broader economy is positive and to decrease when such outlook is negative.

The Risk Off ETN provides investors with the ability to implement a comprehensive “risk off” trade through the purchase of a single, exchange-traded security, OFF. Due to its daily short (inverse) exposure to the Index, the Risk Off ETN provides investors with effective long exposure to "risk off" instruments and short exposure to "risk on" instruments. The Risk Off ETN's value is expected to rise when the outlook on markets and the broader economy is negative and to decrease when such outlook is positive.

“Correlation between asset classes and across geographic regions has risen dramatically over the past two decades as investors move in concert in reaction to changes in the global economic outlook,” said Christopher Yeagley, Managing Director and US Head of Equity Structured Products. “These two ETNs are designed to give investors the ability to take advantage of this in a straightforward manner: if they expect economic growth, they can purchase ONN to express a “risk on” view, and if they don't expect growth, they can purchase OFF to express a “risk off” view.”

The single index underlying both the Risk On ETN and Risk Off ETN, The Fisher-Gartman Risk Index, consists of a mix of long and short positions in various asset classes whose overall value is expected to rise when the outlook on markets and the broader economy is positive and to decrease when such outlook is negative. The Index is comprised of long positions in "risk on" instruments and short positions in "risk off" instruments in the following sectors: energy, agriculture, metals, equities, currencies and domestic and foreign government bonds. The value-based target weightings for the long and short positions are 150% and 50%, respectively, and the Index is rebalanced quarterly to return the weightings to these target levels. Note that the inverse nature of the Risk Off ETN results in performance that is opposite that of the Index, thus rendering the effective exposure as long "risk off" instruments and short "risk on" instruments. Each ETN's effective exposure to the Index's target component weightings is provided in the table below.

^ Given that the Risk Off ETN tracks the short (inverse) performance of the Index, the actual Index weightings have been “inverted” to reflect the effective exposure obtained through an investment in the Risk Off ETN.

* Exposure to all “Sovereign Bonds” components is accomplished through the Index's 34% short (inverse) position in The Fisher-Gartman Sovereign Bond Subindex (Ticker: FGBOND).

** Exposure to all “Equities” components is accomplished through the Index's 46% long position in The Fisher-Gartman Equity Subindex (Ticker: FGEQTY).
