Russ discusses why growth is likely to continue to outperform value for a while.

The value drought persists. Large cap growth, measured by the Russell 1000 Growth Index, is beating value, measured by the Russell 1000 Value Index, by approximately 450 basis points (bps, or 4.5% points) year-to-date and by a similar amount during the past 12 months.

Growth’s recent out-performance conforms to the post-crisis norm. Focusing on price returns, since 2010 growth has outperformed value by an average of approximately 350 bps a year. The out-performance has not only been meaningful, it has been consistent. During the past five years value has only outperformed meaningfully on one occasion, 2016.

Not just about earnings

As others have noted, a large part of growth’s winning streak can be attributed to stellar earnings growth, particularly from technology companies. That said, multiple expansion, i.e. paying more for a dollar of earnings, has played a part as well. Since the 2011 market bottom, the trailing price-to-earnings (P/E) ratio for the Russell 1000 Growth Index is up roughly 65%. In contrast, the value index’s P/E ratio has expanded by a more modest 40%.

But while growth stocks are not particularly cheap, it is not obvious that they are expensive. Valuations are slightly below the long-term average. In other words, the fact that growth looks stretched relative to value is not a function of growth being particularly rich but value being very cheap.

For multiples to converge, the economy needs to get stronger

Growth’s premium to value can be partly explained by the economy. When investors are worried about economic growth, as they have been for much of the recovery, they tend to favor growth as a style. The reason: Even in a weak economy, growth companies can generate organic earnings growth.
