A Traders Guide to Buying the Dips (Part II)

Dec 21, 2013 | Uncategorized

This article presents another twist to the one I posted a few days ago titled “A Trader’s Guide to Buying the Dips”. This article presents a variation known as “Jay’s Pullback System”

First let’s look at the building blocks:

A = S&P 500 daily close
B = 10-day simple moving average of S&P 500 daily close
C = (A – B)
Buy Signal = Variable C declines for 3 or more consecutive days

In a nutshell, if the difference between the S&P 500 index (SPX) and its own 10-day moving average declines for 3 straight days we consider this to be a “pullback”, and thus a buying opportunity.

Trading Rules for Basic System:

When Variable C declines for 3 straight days, buy and hold the S&P 500 Index for 5 trading days. If the decline in Variable C extends itself one or more days, then extend the holding period for that many trading days.

So for example, if Variable C declined for 5 straight trading days, one would buy at the close of the third trading day and then hold for seven trading days

Day        Variable C            Action                                                                         Position
1              Down
2              Down
3              Down                    Buy at close (hold for 5 days)
4              Down                    Hold (Var. C down again; hold for 5 days)              Long
5              Down                    Hold (Var. C down again; hold for 5 days)              Long
6              Up                         Hold (for 4 days)                                                      Long
7              Down                    Hold (for 3 days)                                                      Long
8              Up                         Hold (for 2 days)                                                      Long
9              Down                    Hold (for 1 day)                                                        Long
10           Up                          Sell at close                                                               Long; Flat at close

Figure 1 displays “bullish days for SPX in green.  In the lower clip we see the difference between the close and the 10-day moving average (i.e., Variable C).  A “bullish” period is signaled when that value declines for 3 straight days

Results:

This is a very rudimentary “system” and not suitable for many traders (note this raw system includes no stop-loss provision and does not attempt to filter for and trade with the major trend).

In any event, let’s look at what would have happened if one had followed the rules and held the S&P 500 for 5 trading days following every decline in Variable C of 3 days or more, and earned 1% of annual interest while out of the market.  Those results are displayed (along with the growth of $1,000 achieved by buying and holding the S&P 500 Index) in Figure 2.

Figure 2 – Simple Pullback Systems (blue line) versus Buy and Hold (red line) Dec 1987 to present

-$1,000 invested using this system grew to $13,249 (+1,225%)
-$1,000 invested using buy-and-hold grew to $7,208 (+621%)

So we can reasonably state that these results are pretty good.  Can they be improved? Let’s see.

 Jay’s Pullback System

With this system we will filter for the trend and at times use leverage.
First we will note if the daily close for the S&P 500 Index is above or below its own 250-day moving average.

If Variable C above declines in value 3 straight days:
-If SPX > 250-day moving average we will buy using leverage of 2-to-1
-If SPX < 250-day moving average we will buy using no leverage
-Interest of 1% per year will be assumed when out of the market.

The results of this test appear in Figure 3.

Results:

-$1,000 invested using Jay’s Pullback System grew to $44,541 (+4.354%)
-$1,000 invested using buy-and-hold grew to $7,208 (+621%)

Funds to Use

Mutual Fund: Profunds ticker BLPIX (S&P x 1)
Mutual Fund: Profunds ticker ULPIX (S&P x 2)
ETF: Ticker SPY (S&P 500 x 1)
ETF: Ticker SSO (S&P 500 x 2)

Summary

While the numbers for the leveraged system look pretty good, it should be noted that there are no stop-loss provisions incorporated.  Before you decide to run off and trade any system – particularly one that may use leveraged funds or ETFs, you ought to do some homework and make sure you fully understand and can tolerate the risks involved.

Still, the real point of all of this is simply to note that buying on dips is a valid approach to trade the stocks markets.

A Trader’s Guide to Buying the Dips Part 1

Dec 19, 2013 | Uncategorized

As of 12/13/2013, the S&P 500 has declined for three consecutive days.  Should you care? Well, perhaps.  In Figure 1 we see the growth of $1,000 achieved as follows:

-When the S&P 500 registers 3 (or more) consecutive lower closes, buy and hold for the next 5 trading days.

To be clear, the results shown here assume that you buy at the close of the 3^rd consecutive down day and plan on holding a long position in the S&P 500 for the at least the next 5 trading days.  This holding period is extended one day for each additional day the S&P declines consecutively.  In other words of the S&P 500 declines for 5 consecutive days, you would buy at the close of the 3^rd consecutive down day and hold for 7 trading days.

Not sure of that explanation helped or made things more confusing but there you have it.

 Figure 1 – Growth of $1,000 invested in S&P 500 after 3 (or more) consecutive down closes (December 1987 to present)

In this test, an initial $1,000 grew to $9,869, or +887% (no slippage, commissions, taxes, dividends, interest, etc., just raw price return), with a maximum drawdown of -19.3%.

Filtering for Trend

One of the dangers of this approach is the “Are You Sure You Want to Try to Catch that Falling Safe?” conundrum.  So what happens if we only take the trades that occur when the S&P 500 is in an established uptrend?  If we only take the trades that occur when the S&P 500 is above its 250-day moving average we get some Bad News and some Good News.

The Bad News is that $1,000 grows to $3,935, or +293%.  So clearly a lot of profit potential left on the table.

Using Leverage

Figure 3 displays the growth of $1,000 using the following assumptions:

-If the S&P 500 declines 3 or more consecutive days AND the S&P 500 is BELOW its 200-day moving average, buy and hold the S&P 500 index for 5 trading days

-If the S&P 500 declines 3 or more consecutive days AND the S&P 500 is ABOVE its 250-day moving average, buy and hold the S&P 500 index using leverage of 2-to-1 (via a leveraged ETF or mutual fund) for 5 trading days

-For this test we assume that an annualized rate of 1% interest is earned when no position is held.
In a nutshell, if the stock market is in an objectively identified up trend (i.e., close above 200-day moving average) we will attempt to press our advantage by using 2-to-1 leverage.   When the S&P 500 is below its 250-day moving average we will eschew the use of leverage.

The results for this test appear in Figure 3.

 Figure 3 – Growth of $1,000 invested in S&P 500 after 3 (or more) consecutive down closes using 2-to-1 leverage if S&P 500 > 250-day moving average (December 1987 to present)

Using this approach $1,000 grew to $35,868, or +3,469% (albeit with a maximum drawdown of -20.2%).

 Funds to Use

Mutual Fund: Profunds ticker BLPIX (S&P x 1)
Mutual Fund: Profunds ticker ULPIX (S&P x 2)
ETF: Ticker SPY (S&P 500 x 1)
ETF: Ticker SSO (S&P 500 x 2)

Summary

Does this simple method represent the “Holy Grail of Trading?”  Of course not.  Is it even better than whatever system you are using right now?  I can’t answer that, only you can.  But the main point here is simply to note that dips in the stock market – even in the face of an overall downtrend – tend to be buying opportunities (at least in the short run).

The simple rules presented here represent just one way to exploit this fact.
