MUTUAL FUNDS
Mutual funds receive periodic dividends from some of the securities
held in their portfolios, and they may also have capital gains
from securities that have been sold. As these dividends and capital
gains accumulate, the NAV (Net Asset Value) of the fund's shares
increases by the amount of the dividends and capital gains being
held. (NAV is the total assets owned by the fund divided by the shares
outstanding.) Periodically (anywhere from monthly to annually, depending
on the fund) the fund will make a "distribution" of these capital
gains and dividends to the fund's shareholders, meaning that they
are paid to shareholders.
On the day of the distribution the money being distributed is no
longer a part of the fund's assets and therefore has to be deducted
from the NAV. From the shareholder's point of view it is a "net zero" transaction, because the amount of the distribution remains in his/her account, and the value of the account doesn't change, BUT the fund's
NAV will be reduced by the amount of the distribution -- the shareholder
now owns the distributed assets, not the mutual fund.
For example, on 12/10/93 the NAV of Fidelity Magellan dropped by
$4.18 to $69.36. The closing NAV was the net result of a $0.15
increase in the value of the stock held by the fund (added to NAV),
and a distribution of $4.33 (subtracted from NAV). The account value
of a shareholder owning one share of Fidelity Magellan on the day
before the distribution was $73.54, which was the NAV of one share.
On the day of the distribution, that same account was worth $73.69,
which was the NAV of one share ($69.36) plus the $4.33 distribution.
The shareholder normally has the option of either having the
distribution paid directly to him/her or having it reinvested into
the fund, in which case the number of shares in the account would
increase from 1.000 to 1.062.
If you are charting a mutual fund, you have to adjust previous
data so that the chart makes sense. Otherwise, a day like the one
described above would show Fidelity Magellan making a major down
move, penetrating support and flashing warning signals. To adjust
mutual fund data for distributions, multiply prior data by a factor
that will reduce it proportionately. To calculate this adjustment
factor, we subtract the amount of the distribution from the prior
day's NAV, and divide the result by the prior day's NAV.
Example: Prior Day NAV = 10.00; Distribution = 1.00.
(10.00-1.00)/10.00 = Adjustment Factor of 0.9
In this example all prior data will be multiplied by 0.9.
Unfortunately, mutual fund distribution amounts are not available in the data feed, and StockCharts.com does not make historical data adjustments for mutual funds EXCEPT for Rydex, ProFunds, and Fidelity Select mutual funds, which we track manually.
STOCKS
What about stocks? A dividend actually a distribution and has the
same effect on the price of a share of company stock as a distribution
has on the NAV of a mutual fund share - in the newspaper you will
notice that the amount of the dividend has been subtracted from
the share price on the ex-dividend date. Do we also adjust all historical data for the stock? StockCharts.com, who supplies our data and charts, does; however, most charting sites do not.
There are cases where a company (not a mutual fund) will execute
a transaction that necessitates the adjustment of previous stock
prices due to a distribution. For example, at this writing (12/13/93)
Litton is in the process of spinning off one of its operations, Western
Atlas, into a new company. As I understand it, Litton shareholders
will receive a distribution of approximately one share of Western
Atlas for each share of Litton. This should be handled in the same
manner as mutual fund distributions.
This difficult thing with stock distributions is determining the
exact amount of the distribution. The easiest way I have found is
to get a full quote online on the Ex-dividend date (the date on which
the distribution has been effected and the stock is being traded
at the new price). Check the prior day's closing price -- it will
normally have been adjusted for the distribution -- then subtract
it from the unadjusted closing price in your database. The result
should be the correct amount of the distribution.
Sometimes the quote systems do not pick up the distribution correctly,
so an alternate method of finding it is to check the newspaper to
see if there was a "when issued" version of the stock -- normally
found below the regular stock quote and identified by a "wi" next
to the quote. A "when issued" stock is a tracking stock used to show
the value of the new stock as it will be when it is issued to
replace the old stock after the distribution.
You adjust historical stock data for distributions the same way
you do with mutual funds (described above).
Finally, stock split is also a form of distribution -- additional
shares are distributed to shareholders. Normally this is done in
a straight forward manner, such as a 2 for 1 split. In this case
the shareholder receives one additional share of stock for each
share held. The effect is that the value of all shares is reduced
by half (multiply historical data by 0.5). To determine the adjustment
factor for a stock split, divide the old number of shares by the
new number of shares. Example: The factor for a 3 for 2 split is:
2 / 3 = 0.66666
How to Get Information About Distributions
Now that you know how to handle distributions, your biggest problem
will be in actually finding out that a distribution has occurred.
STOCKS: There are a number of newsletters and web sites
that report stock splits. I recommend www.theonlineinvestor.com for
a free newsletter and web site lists. I also recommend the the
CBOE web site -- get on their mailing list and you receive detailed
information on splits and distributions for optionable stocks.
MUTUAL FUNDS: I am not aware of any online quote system
that reports or adjusts the prior day NAV for mutual fund distributions,
so, if you own a mutual fund and notice that it takes an unexplainable
dive one day, call the fund company or check the quote in the next
day's newspaper.
Some data services do report mutual fund distributions on
the day they occur. For example, Dial/Data reports the distribution
in the "open interest" field of the quote record. If you are
trying to track large numbers of mutual funds, you will need to be
sure you are getting this data and make the appropriate adjustments
to your historical data, or your charts will be totally worthless.
iSHARES: Distributions for iShares are usually made once
a year and may be quite large like mutual fund distributions, so
you can't ignore them like you can a dividend. Unfortunately, iShares
distributions are not reported in the quote systems, nor do data
services report them like they do mutual fund distributions. I was
not even able to get the information from my broker. I recommend
that you check www.ishares.com for information on how to get the
information in a timely manner without having to check the newspaper
every day.
HOLDERS: Distributions for Holders are normally handled
in the same way as stocks, so you can track them down the same way
you would a stock distribution. The CBOE mailing list has been particularly
useful in this regard.
