AutoZone, Inc. (AZO), Ctrip.com International, Ltd. (ADR) (CTRP), Alpha Natural Resources, Inc. (ANR): Should You Buy Now?

On Monday we saw several stock-moving downgrades from high-profile firms. While many of these downgrades are warranted, some are following the leader of prior downgrades, and may create upside for the investor. Thus I am looking at the top downgrades to determine if any present value.

AutoZone, Inc.AutoZone, Inc. (NYSE:AZO)

In my book Taking Charge With Value Investing (McGraw-Hill, 2013) I present a value-finding formula that I call (10-10-10) which has become very popular among the retail investment community. I have literally received 100s of emails regarding this one strategy alone, which explains that (in theory) a company should be fairly valued when bottom line growth, year-over-year stock performance, and P/E ratios all align, and then are favorable to the growth and valuation of the broader market. Of course this is a broad topic, but is important to valuing an established company such as AutoZone, Inc. (NYSE:AZO).

Deutsche Bank gives us a clear example of why this strategy works: The firm downgraded AutoZone, Inc. (NYSE:AZO) to Hold from Buy after saying its 13.34 times 2014’s EPS is greater than its now “fair value.” The firm points to the fact that it “typically” trades at 12.5-13 times earnings. After a year of trading flat (compared to the S&P 500 gaining 13.50%) AutoZone, Inc. (NYSE:AZO) has gotten cheaper while the broader market has gotten more expensive.

If the S&P 500 trades at 14 times 2014’s earnings with less year-over-year growth then the analyst is not properly valuing AutoZone, Inc. (NYSE:AZO) to the premium in the market. This would be the second part of 10-10-10 formula, as the stock is “historically” fairly valued but has not seen an increase in premium relative to the market. Therefore, while I don’t think a great deal of upside is present, I do say that with auto being strong, AutoZone could see 15-20% upside.

Ctrip.com International, Ltd. (ADR) (NASDAQ:CTRP)

According to Goldman Sachs, it’s time to take profits in shares of Ctrip.com International, Ltd. (ADR) (NASDAQ:CTRP), hence the firm cut shares to Neutral. The firm believes that its valuation of 18 times 2014’s expected earnings is too expensive for a company that is expected to see 20% EPS growth from 2014-2017 (per Goldman’s expectations)

Goldman is basically saying that Ctrip.com International, Ltd. (ADR) (NASDAQ:CTRP)’s 20% premium to the S&P 500 based on expected P/E ratios for 2014 is too expensive for a company growing nine times faster than the S&P 500. In an internet industry that typically trades at large premiums to fundamentals, this makes little sense. In my opinion, Ctrip.com International, Ltd. (ADR) (NASDAQ:CTRP)’s 20% premium and its nine times faster growth than the S&P is an indication of value, and although Goldman’s expectations for seasonality weak periods in Q2 and Q3 could create weakness, I do believe that Ctrip.com International, Ltd. (ADR) (NASDAQ:CTRP) is a long-term “buy” if the company maintains bottom line growth of 20%.

Alpha Natural Resources, Inc. (NYSE:ANR)

Alpha Natural Resources, Inc. (NYSE:ANR) has produced one of the greatest periods of loss in the market over the last five years. It has lost 88% of its value during this period, almost 50% during the last year, and 30% in 2013. Thus it has been a continuous downtrend for the stock. However, Standard & Poor doesn’t think it is over, as they lowered their outlook to Negative from Stable.

It’s hard to imagine that shares of Alpha Natural Resources, Inc. (NYSE:ANR) could trade any lower, but S&P expects continued weakness in coal and that pricing will continue to challenge the company’s operational conditions. S&P specifically notes trouble in Central Appalachian thermal and metallurgical coal markets.
