Screen of the Week of Zacks Investment Research:

5 Stocks in Focus on New Analyst Coverage

There's no denying that the lack of consistency in information creates inefficiencies that might result in misinterpretation of stocks. Thus, initiation of coverage by analysts offers critical information on a stock which is of great value to investors.

Coverage initiation on a stock by analyst(s) usually depicts increased investor inclination. Investors, on their part, often assume that there is something in the stock that has attracted analyst attention. In other words, they believe that the company coming under the radar definitely has some value which can be tapped into.

Obviously, stocks are not arbitrarily chosen to cover. New coverage on a stock usually reflects an encouraging future envisioned by the analyst(s). At times, increased investor focus on a stock motivates analysts to take a closer look at it.

However, we have noticed that the average change in broker recommendation is preferred over a single recommendation change.

Analyst Coverage & Price Movement

Interestingly, the price movement is generally a function of the recommendations from new analysts. Stocks typically see an upward price movement with a new analyst coverage compared to what they witness with a rating upgrade under an existing coverage. Positive recommendations - Buy and Strong Buy - generally lead to a significantly positive price reaction than Hold recommendations. On the contrary, analysts hardly initiate coverage with a Strong Sell or Sell recommendation.

Now, if an analyst gives a new recommendation on a company that has limited or no existing coverage, investors start paying more attention to it. Also, any new information attracts portfolio managers to build a position in the stock.

So, it's a good strategy to bet on stocks that have seen increased analyst coverage over the last few weeks.

Screening Criteria

Number of Broker Ratings now greater than the Number of Broker Ratings four weeks ago (This will shortlist stocks that have recent new coverage).

Average Broker Rating less than Average Broker Rating four weeks ago ('Less than' means 'better than' four weeks ago).

Increased analyst coverage and improving average rating are the primary criteria of this strategy but one should consider other relevant parameters to make the strategy foolproof.

Here are the other screening parameters:

Price greater than or equal to $5 (as a stock below $5 will not likely create significant interest for most investors).

Average Daily Volume greater than or equal to 100,000 shares (if volume isn't enough, it will not attract individual investors).

Here are five of the 12 stocks that passed the screen:
