1Q Market Review: Divergence of big & small

The valuation gap between the mature biotechnology companies and their younger siblings is widening as Wall Street continues to assign pharma-like valuations to biotechnology companies with sales and earnings.

As the first quarter stock performance attests, big cap biotech continues to dominate investor attention. After posting a 79 percent gain in 1998, the group of biotechnology companies valued over $1 billion was up 12 percent in the first quarter. Five out of the other six market cap subgroups traded down on the quarter (see A3), and the group over $1 billion is the only one to post gains in both the first quarter of 1999 and all of 1998.

Hit the hardest in the first quarter were companies between $301 and $400 million, which shed 24 percent. The only other gaining subsector on the quarter was the group of microcap companies valued less than $100 million, which added 8 percent - small consolation after losing 40 percent in 1998.

A snapshot of the trailing 12-month price-to-earnings ratios of the top five biotechnology companies by market cap versus the P/Es of the top five pharmaceutical companies shows that Wall Street is warming up to paying similar multiples for biotech companies. This is a departure from a year ago, according to Sven Borho, general partner at OrbiMed Advisors. "Big, profitable biotechs used to trade at a discount to big pharma, fetching 1 times growth rates in mid-1998. Now they're trading at similar valuations of 2 times internal EPS growth rates."

Of the five biotechs, Genentech Inc. (GNE, South San Francisco, Calif.), Biogen Inc. (BGEN, Cambridge, Mass.) and Immunex Corp. (IMNX, Seattle, Wash.) trade at multiples exceeding 60 times last year's diluted earnings
