Bond Prices Relatively Unchanged
Bond prices were in both positive and negative territory
today, with the yield of two-year Treasuries settling up 8 basis
points, the highest level in four and a half years. Bond traders are
uncertain of the direction of interest rates leading into the Federal
Reserve meetings this week. So will the Fed raise interest rates this
week? Yes, No, No, Yes.

Correlation With Apple
A recent article
discusses the correlation that various stocks have with Apple and some
of the stocks are surprising. For example, industrial products
manufacturer Illinois Tool Works
(ITW) has the highest correlation at .61. Payment technology firm
Fiserv and Honeywell have the next highest correlations with Apple.
Facebook and Texas Instruments also have high correlations with Apple,
which is expected since Facebook is a tech stock and Texas Instruments
is a major supplier to Apple. By now, we hope you understand how
important correlation is to diversification, but, as with most numbers,
we need to apply economic rationale to the numbers. There is no reason
that ITW and Fiserv should have such high correlations with Apple, and
in the future, these correlations will likely fall. Remember, what we
really want is the correlations going forward, not correlations in the
past. As Eric Chemi, the author of the article, states in the
accompanying video: "That's where the data can get you and I think
people need to be careful to not get trapped in these types of numbers."
Macy's Options
When a company makes an announcement, most people do not consider that
many of these announcements are in fact real options. For example,
yesterday Macy's made two separate announcements that are both real
options. First, the company announced that it would close 35-40 underperforming stores, the option to abandon. Next, the company announced that it would open Best Buy
outlets in 10 of its stores. While this is a small capital budgeting
decision, it is an option to expand as Macy's and Best Buy both hope the
combination is successful, in which case more Macy's will feature a
Best Buy outlet.

VIX Volatility
The VIX, which measures the volatility of the S&P 500, has recently had an increased volatility,
reaching levels not seen since the financial crisis of 2008. The level
of the VIX is still in the area that generally occurs when the economy
is in a recession. A JPMorgan analyst argued that the increased
volatility was the result of price-insensitive traders who had "trend
following strategies (CTAs), risk parity portfolios, and volatility
managed strategies", all of which served to increase market volatility.

Market Efficiency Wins Again
Skeptics of stock market efficiency are always ready to argue "evidence"
that the stock market is grossly inefficient. One piece of evidence
that has been used in recent years is the performance of hedge funds. An
oft reported statistic is that the average hedge fund return since 1996
was 12.6 percent per year. A recent article highlights research
that indicates this claim is incorrect. Overstated hedge funds returns
are due to the fact that hedge funds self-report returns. So, if a fund has
poor returns, it stops reporting returns. Additionally, when a hedge
fund is started, it will often not report returns until it has
"something to brag about." After removing these biases, the researchers
found that the average annual hedge fund return since 1996 was only 6.3
percent, half of the reported average!
Annuity Sales
The stock market crash in 2008 made many investors nervous. As a result,
many of these investors have searched for more certain investments,
including annuities. We describe annuities as an equal payment at some
specified interval for a fixed period. In an investing prospective,
annuities are an investment vehicle that can have a fixed rate. Although
there is more involved in an annuity, the basics of an annuity are that
an investor deposits money into the account and either immediately or
at some point in the future receives payments. The payments are
calculated like the annuity payments in the textbook. So, the payments
are based off the amount deposited, the interest rate, and the number of
payments. Since annuities are currently paying below 3 percent, it is
surprising that sales of annuities have increased because this lower interest rate results in lower payments than when the interest rate is higher.
Stock And Gold Correlation
Historically, the correlation between the stock market and gold prices
is low, or even negative during some periods. Because of this, gold is
often seen as a good asset for a diversified portfolio since a low or
negative correlation can increase diversification. However, just because
it happened in the past does not mean that it will happen in the
future. For example, while the market dropped on Monday, gold prices also took a hit.
While one day does not a trend make, both the stock market as a whole
and gold are down year-to-date. All of this should be taken as a
warning. Just because two assets have had a low or negative correlation
in the past does not mean that the correlation will hold going forward.
In other words, when using correlation, we want the correlation going
forward but are often forced to use historical correlation.
