Should You Invest in Marvell (MRVL) Based on Bullish Wall Street Views?

The recommendations of Wall Street analysts are often relied on by investors when deciding whether to buy, sell, or hold a stock. Media reports about these brokerage-firm-employed (or sell-side) analysts changing their ratings often affect a stock's price. Do they really matter, though?

Before we discuss the reliability of brokerage recommendations and how to use them to your advantage, let's see what these Wall Street heavyweights think about Marvell Technology (MRVL).

Marvell currently has an average brokerage recommendation (ABR) of 1.14, on a scale of 1 to 5 (Strong Buy to Strong Sell), calculated based on the actual recommendations (Buy, Hold, Sell, etc.) made by 28 brokerage firms. An ABR of 1.14 approximates between Strong Buy and Buy.

Of the 28 recommendations that derive the current ABR, 25 are Strong Buy and two are Buy. Strong Buy and Buy respectively account for 89.3% and 7.1% of all recommendations.

While the ABR calls for buying Marvell, it may not be wise to make an investment decision solely based on this information. Several studies have shown limited to no success of brokerage recommendations in guiding investors to pick stocks with the best price increase potential.

Are you wondering why? The vested interest of brokerage firms in a stock they cover often results in a strong positive bias of their analysts in rating it. Our research shows that for every "Strong Sell" recommendation, brokerage firms assign five "Strong Buy" recommendations.

In other words, their interests aren't always aligned with retail investors, rarely indicating where the price of a stock could actually be heading. Therefore, the best use of this information could be validating your own research or an indicator that has proven to be highly successful in predicting a stock's price movement.

With an impressive externally audited track record, our proprietary stock rating tool, the Zacks Rank, which classifies stocks into five groups, ranging from Zacks Rank #1 (Strong Buy) to Zacks Rank #5 (Strong Sell), is a reliable indicator of a stock's near -term price performance. So, validating the Zacks Rank with ABR could go a long way in making a profitable investment decision.

Zacks Rank Should Not Be Confused With ABR

Although both Zacks Rank and ABR are displayed in a range of 1-5, they are different measures altogether.

The ABR is calculated solely based on brokerage recommendations and is typically displayed with decimals (example: 1.28). In contrast, the Zacks Rank is a quantitative model allowing investors to harness the power of earnings estimate revisions. It is displayed in whole numbers -- 1 to 5.

Analysts employed by brokerage firms have been and continue to be overly optimistic with their recommendations. Since the ratings issued by these analysts are more favorable than their research would support because of the vested interest of their employers, they mislead investors far more often than they guide.

On the other hand, earnings estimate revisions are at the core of the Zacks Rank. And empirical research shows a strong correlation between trends in earnings estimate revisions and near-term stock price movements.

In addition, the different Zacks Rank grades are applied proportionately to all stocks for which brokerage analysts provide current-year earnings estimates. In other words, this tool always maintains a balance among its five ranks.

Another key difference between the ABR and Zacks Rank is freshness. The ABR is not necessarily up-to-date when you look at it. But, since brokerage analysts keep revising their earnings estimates to account for a company's changing business trends, and their actions get reflected in the Zacks Rank quickly enough, it is always timely in indicating future price movements.

Should You Invest in MRVL?

Looking at the earnings estimate revisions for Marvell, the Zacks Consensus Estimate for the current year has declined 5.3% over the past month to $1.35.

Analysts' growing pessimism over the company's earnings prospects, as indicated by strong agreement among them in revising EPS estimates lower, could be a legitimate reason for the stock to plunge in the near term.

The size of the recent change in the consensus estimate, along with three other factors related to earnings estimates, has resulted in a Zacks Rank #4 (Sell) for Marvell. You can see the complete list of today's Zacks Rank #1 (Strong Buy) stocks here >>>>

Therefore, it could be wise to take the Buy-equivalent ABR for Marvell with a grain of salt.
