SKF versus the VIX

In my semi-rant about leveraged ETFs from Monday, I mentioned that the 2X ETFs can be held for longer than one day, especially when volatility is moderate to low. This post takes a closer look at this proposition.

I decided to take the worst case situation and look at the most maligned of the ProShares ETFs: SKF, the UltraShort Financial and its corresponding bullish ETF, the Ultra Financial, UYG.

To compare results to the underlying index, I also included IYF, the iShares Financial ETF.

To investigate performance in the presence of volatility I brought the VIX into the analysis. The following table shows how the performance of each ETF is related to the VIX by calculating the correlation factor. The closer the correlation gets to 1, the more closely the ETF tracks the VIX. The closer the correlation gets to -1, the more the ETF tracks the opposite moves of the VIX.

VIX above 40 1/7/2009 to 4/7/2009 -7% 0.763 -19% -0.474 -21% -0.305 -50%
VIX above 40 9/29/2008 to 12/31/2008 -14% 0.778 -10% -0.386 -30% -0.309 -63%
VIX below 40 and above 20
6/6/2008 to 9/26/2008 47% 0.007 -21% -0.342 -6% -0.466 -23%
VIX below 20 2/1/2007 to 6/5/2008 81% 0.768 66% -0.724 -31% -0.739 -58%

One of the takeaways from the table above is that when the VIX trends upward strongly, as it did in the 3rd quarter of 2008, SKF becomes unpredictable. Indeed, SKF's correlation to the VIX essentially went to zero.

In the fourth quarter of 2008, the VIX was above 40 and swinging wildly (eventually peaking at 90) but it was not trending upward. This is when SKF endured some of its biggest spikes in price and volume. This period comprises one of the examples when IYF went down and, by the end of the period, SKF also registered a loss. You can see in the chart below how SKF's moves are an extreme exaggeration of the moves in the VIX.


In the first quarter of 2009, the VIX remained high but no longer swung so wildly. In the second quarter of 2009, March saw a peak in SKF but as the VIX drifted lower and investors began to think the worst of the market downturn was over, SKF plunged from its March high.

This next chart shows how things looked with the other (non-short) ETFs when the VIX was high. It shows how the Ultra Financial (UYG) severely underperformed the underlying index. This, however, is as it should be during a time when the financial sector was severly underperforming the rest of the market.


This next chart shows how things look when the VIX is trending lower as it has been so far this year. It shows how the Ultra Financial (UYG) has been comfortably outperforming the underlying index for more than four months now.


You might also notice in the first chart above that SKF is performing much more sedately now as the VIX has trended downward.

Conclusion --

One of the odd results of this analysis is that UYG seems much more well behaved than its opposite, SKF. It more closely tracked its underlying index and maintained its expected inverse correlation to the VIX in a range that was reasonable.

SKF was indeed much more unpredictable and volatile. It's correlation to the VIX varied surprisingly and its inverse relationship to the underlying index was also exaggerated.

The only conclusion one can make is that SKF's performance was distorted due to the extreme volatility in the market and the extreme volume that drove the ETF compounded by waves of panic buying followed by frenzied profit taking. SKF was the ETF that corresponded to the sector at the heart of the plunge in world markets and became the vehicle through which everyone attempted to play the epic moves in financial stocks. This one ETF received an inordinate amount of trading which distorted its performance, caused it to suffer discounts and premiums to its true NAV and made settlement difficult at the end of the trading day. Even as volume in IYF spiked during the worst of the downturn, volume in SKF still remained 5 and 6 times that of IYF.

There are several points I am trying to make here:
  • SKF is often held up as an example of why you can't hold 2X ETFs for longer than a day
  • SKF is the exception, not the rule
  • Leveraged ETFs shouldn't be held for the long term but they can safely be held for weeks or months, especially when volatility is moderate or trending downward
  • It is reasonable to say that during periods of high volatility, leveraged ETFs are prone to exaggerated swings and are appropriate only for active traders. Holding periods should be reduced accordingly and stops should be used (always a good idea with leveraged ETFs). In other words, be prudent.
The bottom line is that you can't say all leveraged ETFs should be outlawed because SKF performed unpredictably over investment horizons for which it was not intended.

You can say that leveraged ETFs are appropriate trading vehicles for investors who understand them. Hopefully, this analysis will help that understanding.

Brazil - in a bubble or on a roll?

A couple of years ago, no one recognized the real estate bubble even though it was under everyone's nose. Now, analysts and bloggers are seeing bubbles everywhere they look. One of them, they say is in Brazil whose Bovespa stock market index has doubled in the last 12 months. Does the bubble accusation hold water? I don't think so and here are 7 reasons why Brazil is by no means a bubble economy: Exports have held up over the past year thanks to demand from China for Brazil's soya exports and iron ore. This was helped by the the Brazilian government's drive to improve trade links with Asia and Africa. Export diversification, spurred by a more active trade policy and increased focus on "south-south" trade under current president Lula, helped mitigate the decline in demand from OECD (Organization for Economic Co-operation and Development) countries A "sensible" economic framework has been in place since the 1990's. This has included inflation ...

Time to be conservative with your 401K

Most of the posts I and other financial bloggers write are typically focused on individual stocks or ETFs and managing active portfolios. For those folks who are more conservative investors, those whose main investment vehicle is a 401K, for example, the techniques for portfolio management might be a little different. The news of stock markets falling and pundits predicting recession is disconcerting to professional investors as well as to those of us who are watching our balances in an IRA or 401K sag. What approach should the average 401K investor take? Let's assume that the investor is contributing on a regular basis to one of these retirement accounts. There are two questions that the investor needs to ask: 1. Should I stop putting the regular contribution into stocks? My feeling is that investors making regular contributions are being handed a present by the markets. Every week the market goes down, these investors are lowering their average cost. When markets reco...
