What happens when Info Tech drives the market to record highs

By Jason Goepfert

BOTTOM LINE
As the S&P 500 recorded its recent record highs, only the information technology sector was along for the ride and setting its own records. On average, the other major sectors were down several percent from their highs. Similar records in the S&P, when it was accompanied only by technology, showed a consistent tendency for more gains.

FORECAST / TIMEFRAME
None

Key points:

  • When the S&P 500 recently reached a record high, only information technology accompanied it
  • On average, the other major sectors were more than -8% off their own highs
  • Similar "narrow" drives to record highs didn't have any negative impact on future returns

When the S&P 500 pushed to a record high, technology was the only passenger

The most benchmarked index in the world has reached numerous record closes over the past week, and similar behavior in the past showed a strong tendency to keep going. This time, there are some oddities that we've touched on a few times. It's nothing too worrying, but it's still worth watching in the weeks ahead.

The main reason for the weirdness is that much of the gain in the S&P 500 since December, in particular, has come from a handful of stocks. As a result, the information technology sector is the only one that recorded a record high along with the S&P. As noted by The Wall Street Journal:

The S&P 500 is back at record levels for the first time in two years. Information technology is the only one of the index's 11 sectors that can say the same...A narrow rally is a potentially worrying sign to some investors and strategists. When just a handful of big stocks are responsible for most of the market's gains, it becomes more vulnerable to a downturn if a few of those heavyweights stumble, they say.

The Journal is correct regarding info tech being the only (well, the first) major sector to join the S&P 500 at a record high. Several of the others were close but not quite there.

The other sectors that aren't yet at record highs are off an average of -8.1% from their highs. That's the second-largest divergence dating back to 1927.

Whether it matters or not is really the only thing we're concerned about. Unfortunately, there aren't many precedents to draw from, even with nearly 100 years of history.

Info tech driving gains has not been a warning sign

The table below shows every instance and the S&P 500's forward returns. The lack of participation at new highs from other sectors had no negative impact. Well, there was that pesky signal from 1929, but even then, the S&P gained double-digits before rolling over.

For the information technology sector, returns were generally very good. It did show an extra negative return across most time frames, but it was small.

Across sectors and factors, technology showed among the strongest returns, with financials also doing well.

What the research tells us...

When a handful of large stocks do spectacularly well and drive indexes higher, investors always become concerned about a narrow tape. A lack of participation is a consistent warning sign ahead of major peaks, but we're not seeing too many signs of that just yet. Yes, some gigantic stocks are rolling along and carrying cap-weighted indexes higher, but most other stocks are doing pretty good, too.

There are a few nascent signs of odd underlying behavior, but it's not nearly to the degree that we often see ahead of significant peaks. We'd also include this study - even though info tech was the only sector joining the S&P 500 at a record high, it didn't mean anything nefarious in any of the previous instances, at least for the next several months.

Hypothetical Performance Disclosure: Hypothetical performance results have many inherent limitations, some of which are described below. No representation is being made that any account will or is likely to achieve profits or losses similar to those shown; in fact, there are frequently sharp differences between hypothetical performance results and the actual results subsequently achieved by any particular trading program. One of the limitations of hypothetical performance results is that they are generally prepared with the benefit of hindsight. In addition, hypothetical trading does not involve financial risk, and no hypothetical trading record can completely account for the impact of financial risk of actual trading. for example, the ability to withstand losses or to adhere to a particular trading program in spite of trading losses are material points which can also adversely affect actual trading results. There are numerous other factors related to the markets in general or to the implementation of any specific trading program which cannot be fully accounted for in the preparation of hypothetical performance results and all which can adversely affect trading results.
