Should You Care About Analyst Ratings
Post on: 3 Август, 2015 No Comment
Investing can be a difficult decision that many individuals are willing to abdicate to an analyst. I remember my first stock pick, which had a strong buy rating and a ridiculously large price target. It dropped by 25% within weeks.
Much material has been written on the over-exuberance of ratings associated with sell-side analysts. What we want to know is this: do analyst ratings still matter? Should it be a part of your investment decision?
Comparing Analyst Recommendations and Performance
We will look at major exchanges (U.S.) where analysts more frequently recommend investments to their clients. We will further impose a $1 per share and a 10,000 daily share movement minimum. This drops the stock universe to four or five thousand companies. To make our ‘recommendation test’ relevant, we want at least 3 analysts covering the current years earnings
*(All our tests will be using weekly re-balancing so as to change our holdings as close to a change in an analyst recommendation. A more practical longer holding term will be discussed at the end of the article)
Next, we will compare the performance of companies using the 1 to 5 analyst rating system (1 is strong buy and 5 is strong sell). The following stats will be compound annual growth rates since April 2001.
- Rating of 1 = 14.34% CAGR
- Rating between 1 and 2 = 7.82% CAGR
- Rating between 2 and 3 = 7.1% CAGR
- Rating between 3 and 4 = -0.58% CAGR
- Rating between 4 and 5 = Too few stocks to come up with statistical significance
- I removed the requirement of three analysts covering the current years earnings. This resulted in a compound annual loss of 6% in the bottom category.
It would appear that there is still value in using analyst recommendations. Of course, if you ever purchased a strong buy company just to watch it tank as I have, youll know the value of doing due diligence unless you are basket trading which removes some of the company-specific risk.
Adding in More Strong Buy Stocks
Only 33 stocks appear on average when limiting our selection to companies with an analyst rating of 1 (strong buy), in addition to our other requirements. To expand our trading universe I lowered the required number of analysts from 3 to 2, which brings our average list of stocks up to 85. It also drops our CAGR to 12.29%. Can we enhance our gains beyond a simple ‘strong buy rating’ of exactly 1.0?
Taking Away Your Options
It has been my belief for some time now that stocks with options perform worse, on average, than their non-derivative counterparts. This could be due to a lack of manipulation from institutions, hedge funds, and traders that may utilize leverage. Will using non-optionable stocks enhance our strategy? An 18.39% CAGR says it does. Below is a sampling of these stocks in descending order according to market cap (Screening and chart compliments of Portfolio123):
