ABSTRACTThis paper looks as varying Heterogeneous Autoregressive models that utilize volatility components that have been defined over different periods of time. This paper first implements the Heterogeneous Auto-regressive model of Realized Volatility. Additional volatility components are then included into the model to implement three additional models. Using high frequency, 1-minute pricing data for four different stocks over the time period from 1997 through 2010, this paper looks to differentiate between the in-sample results of these models. Additionally, the time period is then broken up into three shorter periods to investigate the results that may occur with a smaller data set. These results indicate that Leverage Heterogeneous Auto-Regressive with Continuous volatility and Jumps model is the best model to be used. Additionally, the findings suggest that regressing your volatility measures over shorter periods of time can result in more reasonable results. By utilizing the Bayesian Information Criterion, we are able to utilize a measure easily differentiates the strength between models.

I. Introduction
Volatility is extremely important within the stock market and greatly affects the
way that our financial markets operate. There have been a number of proposed models
that hope to improve upon volatility forecasting. This paper hopes to implement a few of
these proposed models and assess their results. Realized variation or volatility is one of
the most common methods of measuring the variance within the market and the first
model utilized makes use of the realized volatility over varying time intervals.
What is striking about many of these models is the simplicity of their structures.
Despite this simplicity, however, these models have been shown to successfully achieve
its purpose in recreating the main features of financial returns. There is no long-memory
volatility within these models, which is usually obtained by using small differences in the
operators, but the model proposed by Corsi (2009) is able to get the same results that are
seen in the empirical and financial data.
II. Volatility Models, Jumps and Leverage
The differing types of HAR models looked at in this paper utilize a couple of
different volatility models, in addition to jumps and leverage, which are then defined over
different periods of time, before being implemented into these models. Here, we define
the realized volatility or variance, the bipower variance, jumps and leverage based on
returns data. First, consider the standard continuous time process that uses a log price,
p (t ), that changes with time
dp (t )=μ ( t ) dt+σ ( t ) dW ( t ) ,(1)
3
where p ( t ) is the log price, μ ( t ) is a continuous and finite variation process, σ ( t ) is a the
volatility of the price movement and W (t )is a standard Brownian motion.
2.1 Returns
Given the log price, p ( t ), we can then use that equation to find the returns for a
stock. Depending on the returns desired, p ( t ) at different times is used to calculate the
intraday geometric returns, which can be calculated using p ( t ), a chosen t days and j
steps within the day.
rt , j=p (t−1+ j△ )−p (t−1+ ( j−1 )△ ), (2)
where j=1 ,2 ,…, M , integer t=1, 2 , …,T . This equation and the possibility for varying
time intervals is useful when working with high-frequency price data because more of the
data can still be used. While including all of the data will produce microstructure noise
that disrupts the results, utilizing larger time intervals allows us to use the data available
while still eliminating some of the noise that impede upon finding results.
2.2 Realized Volatility
While there are a number of ways to calculate variance or volatility using
financial data, but one of the most common ways to do so is using the realized variance
or volatility. The realized variance utilizes the returns equation and sums up the
calculated intraday squared returns,
RV t+1 (△ )=∑j=1
1 /△
rt+ j ∙△ ,△2 ,
(3)
where 1/△will be an integer. The data that we have calculated utilizes 1-minute prices,
but calculates the daily realized variance using 5-minute returns. We can then modify the
4
realized variance values and aggregate them over varying time periods to be used in
volatility forecasting.
2.3 Bipower Volatility
The second type of volatility that was used to calculate our findings was the
standardized realized bipower variation,
BV t+1 (△ )=μ1−2∑
j=2
1 /△
|r t+ j ∙△ ,△||r t+( j−1) ∙△ ,△|,(4)
where μ1is √2π and is the average once the absolute value has been taken of the standard
normally distributed random variable Z. Much of the literature suggests using continuous
variation, but, as bipower variation is continuous, it has been used to get these findings.
The bipower variation allows for two components within quadratic variation and is used
in the calculation of jumps within the pricing data.
2.4 Jumps
Jumps are the results of discontinuities in the pricing process that is seen. Because
the bipower is able to allow for us to separate the quadratic variation process into
separate components, we can use the realized variance and the bipower variance to
calculate the jumps that are found in the pricing data,
RV t+1 (∆ )−BV t+1 (△ )→ ∑t< s ≤t+1
κ2 ( s ) . (5)
Here, the difference between the realized variance and the bipower variance gives us
those discontinuities in the data. To prevent the jumps from becoming negative Andersen,
Bollerslev and Diebold (2007), similarly to Barndorff-Nielsen and Shephard (2004a),
have defined the jumps as
5
J t+1=max [ RV t+1 (△ )−BV t+1 (△ ) ,0 ] , (6)
where the actual empirical measurements have been truncated, which will eliminate any
negative results that are found.
III. Data
3.1 Description
This research used high-frequency stock pricing data was used for four different
stocks. We had access to 1-minute pricing data for a number of stocks and four were
chosen based on the length of their span of available data points. The four stocks
considered in this research were American Electric Power Company (AEP), Baker
Hughes Incorporated (BHI), Entergy Corporation (ETR) and H.J. Heinz Company
(HNZ). All stock data spanned from April 9, 1997 through December 30, 2010 and
includes 3,421 trading days and about 385 1-minute price levels per trading day.
All data was cleaned for obvious discrepancies and was then used to construct the
returns, RV, BV and J components previously discussed. To reduce some of the market
microstructure noise that is present in high-frequency pricing data, as we had access to in
this paper, this paper sampled the prices using 5-minute time intervals.
In addition to implementing various HAR volatility models, this research looks at
the difference between the results from longer data samples and the findings that make
use of smaller data sets. For that reason, for each of the volatility models that has been
implemented on each stock has been a total number of four times for each stock. First,
results have been determined by making use of the entire data set ranging from 1997 to
2010. Additionally, three data sets that range from 1997 to 2002, 2003 to 2006 and 2007
6
to 2010 have been extracted from our total data. This came from the intention of
comparing how the length of the data affected the results of these measurements, as well
as the fact that extracting data points from 2007 to 2010 would help separate the financial
crisis.
IV. HAR Volatility Models
The HAR class of models is one that creates volatility cascades with varying
dependent components. There have been a number of proposed variations on this type of
model which is more manageable because it is a much more simplistic way to look at
results than have been made use of in the past. In addition to being a simplistic model,
there have much of the results have been very strong. This simple model has been able to
create both financial and empirical results that are seen from much more complex
models.
4.1 The HAR-RV Model
This HAR-RV Model is an additive cascade of partial volatilities that was
proposed by Corsi (2009) and has been shown to produce results that are similar to those
with long-memory properties, despite its simplicity. This model considers three volatility
components that correspond with time lags of one day, one week or one month. For this
model, the data was calculated using the realized volatilities for the daily, weekly and
monthly observed realized volatilities. The realized volatility was the square root of the
realized variance that was introduced earlier in this paper. In order to obtain the weekly
and monthly aggregated volatilities, we used the average lag,
RV t ,t+h=h−1 [RV t+1+RV t+2+…+RV t +h ] , (7)
7
where h=1 ,2 , … and represents the number of days for the lags that are being used. This
data used h=5 and h=22 for the weekly and monthly volatilities, respectively. Those two
lags, in addition to the daily values, are most used with these models due to their natural
convenience in the way that they relate to the data. The final HAR-R model is stated as
RV t ,t+h=β0+β D RV t+ βW RV t−5 ,t+ βM RV t−22 ,t +εt ,t+h, (8)
with t=1 , 2, …, T . Of course, any time lag can be used to calculate these results, but
using lags of 5 days and 22 days to represents weekly and monthly lags is a natural way
to implement this model.
4.2 The HAR-RV-J Model
To include the jump calculation discussed previously, we can include that as
another variable on this model to create the HAR-RV-J model,
RV t ,t+h=β0+β D RV t+ βW RV t−5 ,t+ βM RV t−22 ,t +βJ J t+εt ,t+h. (9)
The jumps are an additional variable that could help explain the results that is readily
available and can thus be included to create a new model. This model produced similar
results to the HAR-RV model. Similar to the findings of Andersen, Bollerslev and
Diebold (2007), the R2’s when the jumps have been included are higher. We can see that
jumps are an additional volatility that is certainly relevant and can assist in replacing
some of the data that is lost by the realized variance to produce stronger results.
4.3 The HAR-RV-CJ Model
A way to include further variables into this model, we continue to incorporate
more variables that are based on variation. These two could again include the jump
8
variation, as well as a continuous variation component. Andersen, Bollerslev and Diebold
(2007) defined the jump and continuous variability measures with lags as
J t ,t+h=h−1 [ J t+1+J t+2+…+J t+h ] , (10)and
C t ,t h=h−1 [C t+1+Ct+2+…+C t +h ] , (11)
which are then incorporated into the HAR-RV-CJ model explained as,
RV t ,t+h=β0+βCD C t+βCW C t−5 , t+βCM Ct−22 ,t+βJD J t+βJW J t−5 ,t+βJM J t−22, t+,εt ,t+h (12)
Because the bipower volatility is a continuous variability measure, this research makes
use of that calculation as the additional continuous variation component. Now, we can
notice that the previous HAR-RV-J model is still included within this model, but has
been broken up which could help break down any potential explanations or indications
that are being made by the results. Instead of the findings being found as one number, by
including this continuous variation component, we can split up those results, which may
help us find more applications for our results.
4.4 The LHAR-CJ Model
Looking at the leverage effect and how it relates to the HAR class of models can
by done by considering asymmetric responses from realized volatility on previous daily
negative returns and comparing the relationship between the two measures. This
particular idea stemming from the Heterogeneous Market Hypothesis from Muller et al.
(1997) can be seen through the aggregated negative returns. Corsi and Renò (2009)
implement this idea in one model. Before the regression, however, they define returns
rt=X t−X t−1. This calculation is then used to find the past aggregated negative returns as
rt
( n)−¿=1n ( rt+ …+rt−n+1) I {¿¿ ¿, (13)
9
which includes the indicator function of all the aggregated negative returns, which are
then averaged over varying time intervals, as has been done in other HAR models. The
final Leverage Heterogeneous Auto-Regressive with Continuous volatility and Jumps
model can be stated as,
log V̂ t ,t+h=β0+βJD log (1+J t )+βJW log (1+J t−5 ,t ) +βJM log (1+J t−22, t )+βCD C t+βCW C t−5 , t+βCM Ct −22, t+βrD rt−¿+βrW rt−5, t
−¿+βrM r t−22 ,t
−¿+ε t ,t+h, ¿¿¿
(14)
This model takes the logarithms of the volatility measures that have been previously
used, realized volatility, bipower volatility and jumps, as well as including the aggregated
past negative returns to create this model. By using a cascade, they are able to look at the
results for daily, weekly and monthly forecasting.
V. Results
Upon inspection, there is definitely a trend that indicates that the addition of more
measures of volatility helps to improve upon the performance of the models that are used.
Tables 1 through Tables 4 include the coefficients for the measured variables, their R2
value and the BIC value that corresponds to each respective coefficient. The most striking
trend is that the addition of the log component to the HAR model within the LHAR-CJ
model greatly is able to reduce the BIC values, which helps to indicate that this model
may be the best in measuring these parameters. Additionally, this is the model that
included the most variables, in addition to being the only model that utilized a log
function to define the same variables that had been used in other models. We can see
from the R2 values that the HAR-RV-J model is able to improve on the HAR-RV model
just by including another, readily available volatility model.
10
5.1 Sub-Sampling Data
The sub-sampling data that was calculated for smaller chunks of time over the
whole period of the data were able to greatly help improve upon all of the models. We
can see that much of the results are more consistent and often have improved values for
the significance measures that have been utilized. The R2 and BIC values were often
higher or lower, respectively, amongst the shorter samples of data that had been extracted
from our original price sets.
By shortening the span of the data, the results have more consistency with the
components that are being regressed upon. Particularly with the recent financial crisis, we
can see how the increase in volatility has often left an impression upon the results in the
overall sample and in the sub-sample from 2007 to 2010. While there was less volatility
throughout 1997 to 2006 within the data, we can see how the change in the financial
industry during the last three years of the data set impacted the models.
5.2 Bayesian Information Criterion
One method that was used to evaluate the findings from these models was the
Bayesian Information Criterion (BIC) (Schwarz, 1978), which is a measure for model
selection within a group of parametric models with varying numbers of parameters. This
is a way to see which of the HAR models has performed the best. This value can be
calculated as
BIC=−2l+K log (n ) , (15)
where K is the number of parameters being estimated, n is the sample size of the group
and l is the maximum log likelihood under the model
11
l=lnP ( D|M , θ̂ , τ̂ , υ̂ ), (16)
where M is the model, that is testing the probability of the data, with the rest of the
variables representing model parameters. To choose the best model using this standard,
you must choose the model that obtains the smallest BIC value. The BIC values are
included for each model at the bottom of the tables that include the coefficients for each
variable. These values have also been represented in Figure 1 as a collection of four stem
plots for each stock broken up into one plot for each the overall sample and the three sub-
samples.
Overwhelmingly, we can see that the leveraged heterogeneous autoregressive
with continuous volatility and jumps (LHAR-CJ) model has the smallest BIC values. In
comparison with the LHAR-CJ model, the other three methods explored within this
research have seemingly similar BIC values. The BIC values of the other three models
were often approximately four times that of the BIC value for the LHAR-CJ model that
incorporated the aggregated past negative returns, in addition to using the log of its other
dependent variables.
When looking at the actual values of the BIC for the different models, the sub-
sampling greatly reduces the level of the BIC for any given model. The BIC for the entire
sample often ranges at a value that is nearly four times as large as the BIC values for any
of the sub-samples that were used.
VI. Conclusion
I believe that these results create a strong argument in favor of the proposed
LHAR-CJ model by Corsi and Renò. The BIC is a simple method of measuring the
12
strength of different models and the results shown indicate that the leverage
heterogeneous auto regressive with continuous volatility and jumps model have
significantly lower results than that of any of the other models that were tested. Because
of the nature of the BIC, that is a clear indication that the LHAR-CJ is a better method of
forecasting volatility than the other models used were.
As the models were built onto each other, it was interesting to see the additional
benefits that each additional volatility component was included on the different models.
When another variable is included, we could see that the results had a little more
definition. With the inclusion of more variables included in the model’s equation, we can
better understand how the model is being affected by the variable coefficients. Some of
the variables were linked, such as the jumps and the continuous, or bipower, variations
that were used as components on a couple of models. These measures already have links
due to the nature and relationships between the volatility measures used in this research,
but it still helps to split up findings and makes it possible to understand the results a little
bit more deeply. Finally, much of the results of the shorter samples of data that were used
with the same models were able to see much stronger results once the length or span of
the total data was reduced.
