Buy the dips. That’s a popular investment strategy. It is a popular strategy because it works. But, like almost every investment strategy, it only works sometimes. Buying the dips is only an effective strategy when the dip is actually just a dip within an up trend and not the beginning of a new bear market.
So, like with all investment strategies, it can be useful to define rules so that we know when to buy and when to avoid buying. For this strategy, we will need to identify rules that define the idea of a dip and an up trend.
Let’s start with the rules for an up trend. There are multiple ways to define the direction of the trend but one of the simplest ways is to compare the closing to a moving average (MA). If the close is above the MA, the trend is up. If the close is below the MA, the trend is down. This is just one tool that can be used to define the direction of the trend.
Many analysts have settled on fairly standard MA lengths for defining the trend. When looking at a long term trend, they use the 200 day MA. A short term trend can be defined with the 20 day MA. The 50 day MA can be used to define the direction of the intermediate term trend.

To buy dips, we would like to find stocks in short term pull backs within long term up trends. This means we can require the close to be below the 20 day MA to define a pull back and above the 200 day MA to define an up trend. To be safe, we will also require the stock to be above its 50 day MA.
That is all we need to find dips. But, that would be a long and unmanageable list of stocks. To refine the list, we can add a price filter. We will limit our search to stocks that are trading under $5. This kind of cheap stock can be capable of making an explosive price move.
As an added filter for quality, we will require the company to be profitable. This means the price to earnings (P/E) ratio will be greater than zero. This step is not needed but eliminates some lower quality stocks that have no earnings and reduces the risk of the strategy.
We can set this screen up using the free stock screener at FinViz.com. The exact filters selected are shown below.

It is important to remember that the list of stocks you get when you run the screen may vary from our list. That is because price changes throughout the trading day as do the values of moving averages. Fundamental data could also be updated between the time we ran our screen and when you ran the same screen.
More important than the specific stocks is the process we followed to find the stocks. To find these stocks, we developed quantitative rules based on a logical premise. We wanted to buy stocks in long term up trends that are pulling back in the short term.
This screen can be run at any time. That identifies buys and then a trader needs to add rules for selling. For example, a break below the 200 day moving average could be a sell rule. More risk averse traders could sell on a break below the 50 day moving average.
When selling, it will be important to have a process in place to reinvest the cash. For example, a trader could rerun this screen and find new buy candidates. This may lead to more buy candidates than the trader can use.
In that case, a ranking system would be useful. FinViz.com allows traders to sort on any criteria that is shown. Sorting by the price to earnings (P/E) or price to sales (P/S) ratio could be used to find value. Technical indicators available at that site could also be used to sort the buy candidates.
With rules for selling, this screen could form the basis of a complete investment methodology. At that point, all that would be required for trading is discipline to follow the rules, always selling when the signal is given and always buying new positions when stocks are sold.
