Are these bond etfs any more tax efficient than others?

A look at VIX ETFs and ETNs

TVIX recap

Debunking the myth that trading in VIX related ETFs is a concern for the markets

"In terms of holdings, the fund has a heavy focus on health care (41.7%) and industrial revenue (28.3%) bonds which comprise the lion’s share of the assets. State exposure is also pretty spread out as California bonds comprise about 18.3% of the fund while New York bonds are another 11.1%. Beyond these two, the rest of the top five is rounded out by the territory of Puerto Rico (8.5%), and then the states of New Jersey (7.6%) and Ohio (6.9%). Maturity levels are tilted towards the longer end of the curve giving the fund a greater focus on yield but also on interest rate risk as well. Thanks to this, the fund pays out a 30 Day SEC Yield of 5.55%, a level that transfers over to 8.5% in tax equivalent terms for those in the top tax bracket."

The graphic below attempts to map the herd onto an x-axis for target duration and a y-axis for leverage. In addition to these important criteria, I have also further delineated the group by identifying the four ProShares ETFs in black (the balance are all ETNs), highlighting the five optionable ETPs with a red O preceding their ticker and flagging the two VIX ETPs that have some non-VIX components (in the form of the S&P 500 index) with a black triangle. For good measure I have identified the issuer with a parenthetical one letter abbreviation (Barclays,VelocityShares, ProShares and UBS).

It is worth noting that earlier in the month S&P and VelocityShares announced several new VIX futures strategy indices that hint at future VIX ETPs, all of which will include both a long leg and a short (inverse) leg.

The VIX ETP space is already an exciting one, with over $2.1 billion in assets and daily volume of over 45 million shares per day. As exciting as 2011 has been in this space, things look to be heating up even more in 2012.
