Silicon Motion Is Considered a Good Investment by Brokers: Is That True?

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?

Let's take a look at what these Wall Street heavyweights have to say about Silicon Motion SIMO before we discuss the reliability of brokerage recommendations and how to use them to your advantage.

Silicon Motion currently has an average brokerage recommendation of 1.11, on a scale of 1 to 5 (Strong Buy to Strong Sell), calculated based on the actual recommendations (Buy, Hold, Sell, etc.) made by nine brokerage firms. An ABR of 1.11 approximates between Strong Buy and Buy.

Of the nine recommendations that derive the current ABR, eight are Strong Buy and one is Buy. Strong Buy and Buy respectively account for 88.9% and 11.1% of all recommendations.

Brokerage Recommendation Trends for SIMO

While the ABR calls for buying Silicon Motion, 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.

Zacks Rank, our proprietary stock rating tool with an impressive externally audited track record, categorizes stocks into five groups, ranging from Zacks Rank #1 (Strong Buy) to Zacks Rank #5 (Strong Sell), and is an effective indicator of a stock's price performance in the near future. Therefore, using the ABR to validate the Zacks Rank could be an efficient way of making a profitable investment decision.

Zacks Rank Should Not Be Confused With ABR

In spite of the fact that Zacks Rank and ABR both appear on a scale from 1 to 5, they are two completely different measures.

Broker recommendations are the sole basis for calculating the ABR, which is typically displayed in decimals (such as 1.28). The Zacks Rank, on the other hand, is a quantitative model designed 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.

In contrast, the Zacks Rank is driven by earnings estimate revisions. And near-term stock price movements are strongly correlated with trends in earnings estimate revisions, according to empirical research.

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.

There is also a key difference between the ABR and Zacks Rank when it comes to freshness. When you look at the ABR, it may not be up-to-date. Nonetheless, since brokerage analysts constantly revise their earnings estimates to reflect changing business trends, and their actions get reflected in the Zacks Rank quickly enough, it is always timely in predicting future stock prices.

Is SIMO a Good Investment?

In terms of earnings estimate revisions for Silicon Motion, the Zacks Consensus Estimate for the current year has increased 0.8% over the past month to $3.55.

Analysts' growing optimism over the company's earnings prospects, as indicated by strong agreement among them in revising EPS estimates higher, could be a legitimate reason for the stock to soar 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 #2 (Buy) for Silicon Motion.

Therefore, the Buy-equivalent ABR for Silicon Motion may serve as a useful guide for investors.
