Given the recent run-up in the market last week, here's a screen I've been using recently for my own stock picking.

First, it focuses on the top Zacks Ranked Sectors and Industries. Then it focuses on the Zacks Rank #1s, #2s and #3s, which are Strong Buys, Buys and Holds, respectively. But then it selects the outperforming stocks with the smallest percentage price change over the last 4 weeks.

Why would I do something like that?

Here's why.

You've probably heard the old adage that roughly half of a stock's price movement can be attributed to the group that it's in. And that's true. In fact, oftentimes, even a mediocre stock in a top group will outperform a top stock in a poor group for this very reason.

Now, take a look at any top group. You'll see plenty of fantastic stocks with some impressive price gains in there. But not every stock in every group moves in lockstep at the exact same time. Some will move more than others at any given time.

So by focusing on the stocks with the smallest percentage price change with fundamentals that are just as good as those making the biggest price change, you might find yourself getting into the stocks ready to make the biggest potential catch-up move.

Here's how to set up that screen:

• Best Zacks Ranked Sectors -- Best 8 
We're screening for only those stocks with the best (lowest) average Zacks Rank. With 16 sectors, the best 8 sectors give us the best 50% of sectors.

• Best Zacks Ranked Industries -- Best 132 
Next step is to get only the best Zacks Ranked Industries coming thru. Since there are 264 'X' or expanded industries we look at, the best 132 will give us the best 50% of industries. But note that only the industries that also happen to be in the top sectors will get thru. If an industry is ranked as one of the best but it's outside of the top sector rank, it will not get thru.

• Zacks Rank less than or equal to 3
Now the screen gets narrowed down even more by looking at only the Zacks Rank #1s, #2s and #3s. No Sells or Strong Sells (Zacks Rank #4s and #5s) allowed.

• Price and Avg. Volume greater than or equal to $5 and 100,000 shares 
Only stocks over $5 with at least an average of 100,0000 shares traded daily will be considered.

• Relative % Price Change -- 4 Weeks greater than 0 
This means we're screening for only those stocks that have outperformed the market (S&P 500) over the last 4 weeks.

• % Change in Price -- 4 Weeks: Bottom 50 
Then finally we're scanning for the bottom 50 stocks with the lowest percentage price change over the last 4 weeks. So while all of these stocks have outperformed the market, they increased in price less than their peers.

So each one of these stocks is in a top Sector and top Industry within that Sector. This alone will tip the odds of success in your favor by a great deal when you consider that the best Zacks Ranked groups outperform the worst ones by a factor of 2 to 1.

Then by selecting those stocks with the best Zacks Rank along with the best price performance over the last 4 weeks, you now have only a list of winners from which to choose from.

And from that list of winners, we're selecting the ones that have gained less than their peers on that list. Remember, these stocks aren’t 'dogs' or unresponsive stocks. Quite the contrary; they have all outperformed the market. It just so happens that they increased less than the others on the list. But because they are a top rated stock in a top rated industry, we've singled these out as the ones that could make the biggest move to 'catch-up' to the others.

It's an interesting screen that has generated a lot of great names.

Here are 5 from that list:

(CSGP - Snapshot Report) CoStar Group 
(CW - Snapshot Report) Curtiss-Wright 
(HLS - Snapshot Report) Healthsouth 
(INGN - Analyst Report) Inogen 
(PKI - Analyst Report) PerkinElmer

All great looking stocks that seem to have lots more upside in store for them.
