Levered ETFs are Toxic. Here’s Why.

April 20th, 2009 at 9:29 am » Comments Off

Leveraged Exchange Traded Funds (ETFs) such as FAZ, FAS, and SKF are designed to multiply the DAILY PERCENTAGE change of the underlying index by factors of 2 or 3. They are thus toxic to your wealth and must not be held. Here’s a simple explaination of why. Take the FAS which is the 3X of XLF, the Financials fund. When XLF rises 1% in a day, the FAS is supposed to rise 3%. When things are going your way, everything is fine. But when the XLF drops, very bad things happen to FAS.

Have a look at this table:
FAS vs XLF

On day 1, XLF rose 10% so FAS rose 30%. Great, you’re in the money.

But on day 2, XLF dropped back down to its starting price of $10.00, a decline of 9.09%. The bad news is that FAS declined 3X this amount or -27.27%. This takes its share price down to $9.45 instead of the $10 that you might expect.

So whereas XLF is unchanged after 2 days, FAS is down 5.45% after those same two days.

Why? The power of daily compounding instead of cumulative compounding. The leveraged ETFs are structured in a way that they compound on daily percent changes, not cumulative price changes. The day 2 decline of FAS should only be 23.08% to take it back to its original $10.00 per share price. But because it is 3X of XLF’s daily change, instead it declines 27.27%.

Said another way, the leveraged ETFs operate on the daily percent change not on the price of the underlying index.

Definitely not a buy and hold type of ETF! Not even for one day. Traders: set tight stops!



Cramer says SKF doesn’t work right. Is he right?

February 25th, 2009 at 6:21 pm » Comments Off

On Jim Cramer’s Mad Money show on Monday February 23rd, Jim said about SKF , the 2X UltraShort Financials ETF:

"…they don’t even perform as expected. The index the SKF tracks is down 14% over the past three months, so you’d figure an ETF that double or triple shorts that index would offer great returns, right? Wrong. The SKF is down 28% over the same time period.

I took a quick calculation of XLF vs SKF to see if he is right. I brought weekly historical quotes from Yahoo finance into a spreadsheet, inverted the SKF’s weekly returns and divided by two and charted it. Here’s the chart, you decide if he’s right.

Investments for Inflationary Times (to Come?)

February 19th, 2009 at 9:37 am » Comments Off

The Austrian economists anticipated the present crisis. Should we listen to them when it comes to their predictions about what comes next? In one voice they are saying we will experience inflation unlike we’ve seen in the USA in over 100 years. Inflation is defined as the increase in the supply of money and credit. We are certainly experiencing an increase in the supply of money at present. But the draw-down of credit is counter-acting the monetary inflation and we are hovering in inflationary stasis at present.

Fed Chairman Ben Bernanke said the same thing on February 18th:

Some observers have expressed the concern that, by expanding its balance sheet, the Federal Reserve will ultimately stoke inflation. The Fed’s lending activities have indeed resulted in a large increase in the reserves held by banks and thus in the narrowest definition of the money supply, the monetary base. However, banks are choosing to leave the great bulk of their excess reserves idle, in most cases on deposit with the Fed. Consequently, the rates of growth of broader monetary aggregates, such as M1 and M2, have been much lower than that of the monetary base. At this point, with global economic activity weak and commodity prices at low levels, we see little risk of unacceptably high inflation in the near term; indeed, we expect inflation to be quite low for some time.

He acknowledged that they are inflating. But he threw a red herring into the mix by talking about weak economic activity and low commodity prices (Heh, except gold, right Ben?) trying to infer that they are somehow the cause of inflation. No, they are the result of inflation. Next, he went into how they will correct their inflation:

However, at some point, when credit markets and the economy have begun to recover, the Federal Reserve will have to moderate growth in the money supply and begin to raise the federal funds rate. To reduce policy accommodation, the Fed will have to unwind some of its credit-easing programs and allow its balance sheet to shrink. … However, the principal factor determining the timing and pace of that process will be the Federal Reserve’s assessment of the condition of credit markets and the prospects for the economy.

Bernanke recognized that the plane is in a nosedive and at the last minute he plans to push on the stick and go airborne again. I hope it is not a cloudy day when he has to judge how far the plane is from the ground. He wrapped up his thoughts on inflation and how to avoid it:

As we consider new programs or the expansion of old ones, the Federal Reserve will carefully weigh the implications for the exit strategy. And we will take all necessary actions to ensure that the unwinding of our programs is accomplished smoothly and in a timely way, consistent with meeting our obligation to foster maximum employment and price stability.

What do *you* think the chances are that the Fed will get all of the necessary actions right? Have they gotten the necessary actions right up to this point? Let us examine a scenario where they are not able to get it right and we do indeed experience undesirable inflation, which I will define to be anything above 5% annually.

How might the various asset classes be affected in times of inflation? To answer this question, I utilized Simba ’s spreadsheet for back-testing portfolios (which I imported into Google Spreadsheets) to do a correlation between CPI (Consumer Price Index, the government’s official inflation number) and various stock fund, bond fund, and gold returns. The data in the spreadsheet uses annual returns of Vanguard index funds along with the yearly closing price of gold from the years 1971 – 2008.  The spreadsheet already calculated the cross-correlation between each of the mutual funds and it lists the annual CPI index. So it was very easy to drop the CPI into one of the mutual fund slots and instantly see the correlation between every asset class and inflation. Here are the results, sorted by correlation:

Asset Class Ticker Correlation
T-BILL (money mkt) VMPXX 0.63
GOLD GOLD 0.52
Long Term Govt Bnd VUSTX -0.40
Short Term Trsry VFISX 0.28
Commodities PCRIX 0.25
5 Yr T VFITX -0.24
Wellesley Fund VWINX -0.21
Wellington Fund VWELX -0.16
Small Cap Grwth VISGX 0.13
Total Bond VBMFX -0.12
Small Cap NAESX 0.11
EAFE Dev VDMIX -0.10
Europe VEURX -0.10
Intl Value VTRIX -0.10
EAFE85/EM15 EAFE/EM -0.09
500 Idx VFINX -0.09
Large Cap Grwth VIGRX -0.07
Total Market US VTSMX -0.06
Simulated TIPS S-TIPS 0.06
Pacific VPACX -0.06
Emerg Mkts VEIEX -0.06
Large Cap Value VIVAX -0.04
Small Cap Value VISVX 0.04
REIT VGSIX -0.01
Windsor Fund VWNDX -0.01
Mid Cap VIMSX -0.01
Micro Cap BRSIX 0.00

The table shows those asset classes that were most closely correlated with the CPI at the top. Note in the third column that a value of 1 would mean the asset is perfectly correlated, -1 would mean perfectly correlated inversely (it went down exactly as CPI went up), and 0 means there was no correlation: it was random.

So we see that those assets that were most highly correlated with CPI were T-bills, gold, long-term government bonds (inversely), short-term Treasuries, and commodities.  Everything else was below 0.25 correlation. Interestingly, micro cap stocks were totally uncorrelated with inflation.

So how did a portfolio of those assets perform during the years 1973-1981 in which CPI was 8.7, 12.3, 6.9, 4.9, 6.7, 9, 13.3, 12.5, and 8.9%?

I constructed a portfolio along the lines of the Harry Browne Permanent Portfolio (HBPP invests 25% each into total US stock market, long-term bonds, money market, and gold) but I added some small cap value, micro cap, and eliminated the long-term bond fund. I then back-tested that portfolio during those inflation years. Here is the portfolio what I came up with:

The Inflation Portfolio:

VISVX (Small Cap Value) 15%
BRSIX (Micro Cap) 15%
PCRIX (Commodities) 10%
VMPXX (Money Market) 45%
Gold 15%

The "Inflation Portfolio" had a CAGR (Compound Annual Growth Rate) of 15.5% and a risk (as measured by standard deviation) of 10.5%. Plotting that on a chart, here’s what it looks like compared with some other portfolios and the assets themselves:

Inflation Portfolio Return vs. Risk

The chart shows plots for various portfolios during those inflation years. The plot point directly above HBPP simply substituted BRSIX for VTSMX in the HBPP. The major components of the Inflation Portfolio are also plotted separately showing how volatile gold and BRSIX were themselves. When tempered together with VMPXX, the risk came down considerably while retaining significant returns. You can see all of the rest of the details in the Google spreadsheet that I created for this scenario and you can test out other hypotheses yourself.

The Inflation Portfolio worked from 1973 through 1981. If we see inflation return, would it work again? Some folks are discussing these findings at the Bogleheads forum if you want to chime in.

Please note this is not a recommendation to invest your net worth in the Inflation Portfolio!



Corrected 12 Month Rolling Returns

February 14th, 2009 at 11:51 am » Comments Off

In a previous posting , I calculated the 12 month rolling returns for all IFA portfolios.

That posting is in error (that I do not believe was my fault). I have corrected it. It turns out that Feb 1, 2008 thru Jan 31, 2009 was not the worst 12-month rolling period, but it did come close.

I’ll be watching to see what happens at the end of this month.

Here is the corrected chart.

Bet Against Cramer, Make Money

February 11th, 2009 at 8:25 am » Comments Off

Barrons continues their analysis of Jim Cramer’s Mad Money stock recommendations. Bottom line is that their analysis confirms what I learned by experience back in 2006: Cramer’s stock picks are worse than just buying and holding index funds. They actually suggest that buying short-term in-the-money puts on Jim’s recommendations can make you money. They say, "Those bets could earn over 25% in a month, Chen concludes, at the expense of Cramer’s fans." Hmmmm, maybe I’ll try that.



Backtest Portfolio Challenge

February 10th, 2009 at 2:47 pm » Comments Off

[Update: Corrected the image. Note that the Bogle portfolio is corrected in the Google Spreadsheet - to some extent.]

I have copied Simba’s Backtest Portfolio spreadsheet from the Bogleheads forum into a Google Spreadsheet that you can use to back test a portfolio of Vanguard mutual funds and compare their performance from 1972 – 2008 to the IFA Index Portfolios. Combine the funds any way you like and compare them against IFA’s twenty portfolios. I included the "returns" for gold there for your convenience.

This graph from that spreadsheet shows the plots of a few others including the Coffeehouse portfolio, Harry Browne’s Permanent Portfolio, Scott Burns’ Four Square portfolio, and a couple of others along with IFA’s portfolios (they follow a nice line). Unfortunately, Google spreadsheets doesn’t do labeling very well on the data points. I would have liked each point to be colored and have a legend identifying those colors. Anyway, remember you want to be at a point at the top left on this graph. The line that is formed is called "The Efficient Frontier" beyond which it is difficult if not impossible to achieve. The strong correlation between returns and risk is evident.  However, it is easy to be bottom right!

Return vs. Risk

If you want to play with the spreadsheet yourself, feel free to bring it up. You’ll need a Google account. Leave the years to be 1972 – 2008 in order for the comparisons to be valid. Here’s the link:

But wait, there’s more!

IFA is now allowing you to submit your past financial statements to them so that they can compare you’re portfolio’s performance against their index portfolios. Go their web site at ifa.com to learn more. Here are some comparisons they have already performed.

Downdraft Keeps A Rollin’ (corrected)

February 3rd, 2009 at 9:47 am » Comments (0)

At the end of October 2008 we experienced the worst 12-month rolling period for stocks in 50 years. Then at the end of November we outdid that.  Now at the end of January 2009 we have a new low for a 12-month rolling period in many indexes and portfolios. We came close to the worst rolling 12 months again, but did not pass it.

The following table is taken from ifa.com, combining the returns for 11 months from 1 Feb 08 through 31 Dec 08 and the 1 month return for Jan 09.

Here is the corrected table.

Can the Free Market Work in the USA?

January 27th, 2009 at 4:49 pm » Comments (0)

Let’s say we suddenly start doing everything right according to the Austrian economics playbook. We go on the gold standard and abolish the Federal Reserve. We drastically cut back federal government spending, including all bailouts. We pull back from all overseas engagements. Would it work? Meaning, would we end up more prosperous in the long term than if we stay the current course?

First, can you imagine the immediate shock the the economy? Could anyone really process all of these changes at once, including all of the second-order effects and how they would impact your particular situation? Shocking if done instantaneously. Even shocking if done over the span of one year. But big deal. Get over it. We can be shocked and still survive, right?

Yeah, if the USA were a closed system I think we would be just fine. We would trade our gold for the farmer’s corn. Farmers would trade gold for tractors. Tractor builders would trade gold for houses. On and on. We would employ all the former government workers as road builders. New banks would arise in cities eager to lend us some gold for capital projects. We would do just fine here in the USA.

It is the fact that the USA is not a closed system that complicates the issue. See, in this process we trade dollars for gold. Each dollar is worth 1/900 oz of gold (let’s say). Bring in your pieces of paper, your Federal Reserve Notes, to the bank and they will give you gold coins or a receipt for 100%-reserve gold coin storage.

So now we all have gold in our pockets. And we want to buy a giant LCD TV. With what exactly and from where? Dollars? Ha, they’re gone now. A TV made in the USA? Yeah, right. You gotta give up some gold to some other country. So we load up our Wal-Marts, our Dollar Trees, and our shopping malls with stuff that we trade away our gold for. That represents an outflow of gold from USA. To keep the system in balance, don’t we need a corresponding inflow of gold? Otherwise someday we completely run out of gold, right? Can’t just print more gold can we?

It is the same scenario with any government that is left over. How are they going to pay out Social Security in gold? How are they going to send thousands of troops overseas and build billion-dollar airplanes and pay people to read newspapers in fancy offices? Since they don’t have a gold mine to readily tap into, they either have to take away your gold, or have to borrow gold from China, or they have to stop spending gold. The first option quickly reaches either a point of diminishing returns or reaches a point of torches and pitchforks. The third option is their option of last resort. Which leaves us with the USA borrowing gold from China. Which is kind of making my head spin trying to think of how we are going to come up with the gold to not only pay that back but also to pay the interest.

But maybe that is the point. We would have to figure out some way of getting gold from other countries. We would have to actually make or do things that they want. For example, we could trade our tractors and our corn for their gold. We could build houses for them. We could even help build their roads. Either that or we build our own LCD TVs and stock our Wal-Marts and Dollar Trees ourselves. Shocking isn’t it? Economics does work.

As I ponder this scenario, I realize just how fortunate and prosperous we in the USA have been these past few decades. Being able to "manufacture gold out of thin air," that is, print dollars to trade to foreigners. We are so lucky that they want our fiat dollars. Because that guy reading the newspaper really isn’t a very good road builder.
