Last week I highlighted the Top 10 Value Stocks In The S&P 500 noting that “value will have its day in the sun” in 2018.

This is not a widely held view considering the Russell 1000 Growth index (IWF) has returned 32.2% over the last year while the Russell 1000 Value index (IWD) has returned only 14.7%. Furthermore, high flying Netflix (NasdaqGS: NFLX) jumped to another all-time high after reporting Q4 numbers on Monday after the bell. Total subscriber growth increased 25.4% YoY which helped send the company’s market cap to over $100 billion. The chart below highlights Netflix amazing growth as well as its -$510 million cash burn in Q4 (-$2 billion in fiscal year 2017).

Netflix is a timely reminder of just how much momentum these growth stocks continue to have in this market, no matter what valuation multiple they trade at. And while research suggests owning high quality value stocks significantly outperforms in the long-run, high quality growth stocks (such as Netflix) still have steam. Therefore, I decided to find companies that may be masquerading around as high growth stocks but really are not to be trifled with.

In order to find these pricey stocks, I downloaded the list of S&P 500 constituents and then used finbox.io's spreadsheet add-on to find which companies had the following:

1) a P/E multiple that trades above its comparable public companies, and

2) projected 5-year earnings growth that's below its comparable public companies.

OR

3) an EBITDA multiple that trades above its comparable public companies, and

4) projected 5-year EBITDA growth that's below its comparable public companies.

AND

5) has downside as calculated from finbox.io's fair value > 20%.

Here are the 10 most expensive stocks in the S&P 500 that I found.

Analysts covering the stock often compare the company to a peer group that includes Duke Realty (NYSE: DRE), DCT Industrial Trust (NYSE: DCT), First Industrial Realty Trust (NYSE: FR) and EastGroup Properties (NYSE: EGP).

The company's LTM EBITDA multiple of 27.1x is above all of its selected comparable public companies: DRE (14.9x), DCT (24.8x), FR (19.8x) and EGP (22.7x). Therefore you would expect the company's future growth to be above its peer group. However, ProLogis' projected 5-year EBITDA CAGR of 4.8% is only above DRE (-3.7%) and below DCT (9.1%), FR (6.4%) and EGP (7.2%).

On a comparable company basis, selected benchmark companies include CBL & Associates Properties (NYSE: CBL), Brixmor Property Group (NYSE: BRX), Kimco Realty (NYSE: KIM) and Federal Realty Investment (NYSE: FRT). Higher growth companies typically trade at higher valuation multiples but this does not appear to be the case for Macerich as shown below.

The company's projected 5-year net income CAGR of -28.7% is well below its entire peer group: CBL (-14.3%), BRX (18.1%), KIM (-5.1%) and FRT (4.0%). However, Macerich's P/E multiple of 64.7x is above CBL (10.4x), BRX (16.3x), KIM (19.3x) and FRT (30.6x).

The company appears to be expensive on a future cash flow basis as well.

Align Technology (NasdaqGS: ALGN) manufactures and markets a system of clear aligner therapy, intra-oral scanners, and computer-aided design and computer-aided manufacturing (CAD/CAM) digital services. The company was founded in 1997 and is headquartered in San Jose, California.

The company's valuation multiples currently look expensive relative to peers: Cooper Companies (NYSE: COO), Dentsply Sirona (NasdaqGS: XRAY), AbbVie (NYSE: ABBV) and Cutera (NasdaqGS: CUTR).

Align Technology's LTM EBITDA multiple of 60.1x is above COO (20.8x), XRAY (22.7x), ABBV (16.6x) and CUTR (54.9x). Cutera's multiple is only slightly below Align Technology's but Wall Street analysts project that the former will grow its cash flows by 62.8% annually over the next five years. This is well above Align Technology's forecasted five-year EBITDA CAGR of 25.2%.

However, notice how the company's projected 5-year EBITDA CAGR of 8.9% is only above HRC (7.7%) and below EW (13.8%), VAR (10.1%) and BDX (20.1%). This implies that the market's valuing Intuitive Surgical at a premium.
