'Magnificent 7' Mega Cap Tech Stocks Have Dominated Markets This Year. That's Not Good.

The market's biggest tech stocks have overpowered the S&P 500 so far this year, driving the vast majority of the benchmark's year-to-date gains and creating a worrying imbalance that could test its performance over the second half of 2023.

With the Nasdaq Composite riding its longest weekly winning streak in three years, and closing last night at the highest levels in nine-months late Thursday, tech stocks have been the lynchpin to this year's overall performance, powered by a surge in demand linked to AI-related technologies, impressive earnings generation and an easing in broader market interest rates tied to fading inflation prospects.

Bank of America's closely-tracked weekly 'Flow Show' report indicates that tech continues to attract investor cash, drawing in $8.5 billion last week, the strongest on record, with inflows in May pegged at the second-highest of all time. 

Overall stock inflows, in fact, neared $15 billion last week, the highest since February, as investors bet on a pause in Fed rate hikes and the conclusion of a debt ceiling deal in Congress that will avoid a U.S. default. 

"Interest rate stabilization, signs of receding inflation, and a potential peak in the terminal rate by this summer have helped bring buyers back into the (Big Tech) space," said Adam Turnquist, chief technical strategist and Jeffrey Buchbinder, chief equity strategist for LPL Financial. "Rising recession odds in the U.S. have further increased the relative attractiveness of mega-caps, as investors have shown a growing propensity for higher quality, well-established companies with sustainable growth profiles and fortress balance sheets."

The influence of so-called Big Tech stocks, which Bank of America has dubbed 'The Magnificent Seven', however, has been undeniable, with Apple  (AAPL) - Get Free Report, Microsoft  (MSFT) - Get Free Report, Google  (GOOGL) - Get Free Report, Meta  (META) - Get Free Report, Amazon  (AMZN) - Get Free Report, Tesla  (TSLA) - Get Free Report and Nvidia  (NVDA) - Get Free Report comprising around 8.8 percentage points of the S&P 500's year-to-date gain of around 10%. 

The 'Magnificent Seven' also comprise around 31% of assets under management in its Global Wealth and Investment Management division, a 44% increase since the start of the year. 

Nvidia's record surge last week, which added around $185 billion in market value to the Santa Clara, California-based chipmaker following a blowout first quarter earnings report, means the stock has contributed to around a fifth of the S&P 500's year-to-date gain, despite only representing 2.7% of its index weight. 

That kind of move, as well as the broader Big Tech dominance, highlights a persistent concern for investors searching for clues as to the market's overall resilience: a lack of breadth.

Turnquist and Buchbinder note that only around 25% of S&P 500 stocks are outperforming the benchmark this year, with less than half trading above their 200-day moving average, a condition that suggests limited buying opportunities and a lack of investor conviction. 

In fact, some 493 stocks in the benchmark have provided only 2.2 percentage points of its entire year-to-date advance, according to Bank of America data.

"In a typical bull market or even a developing one, widespread participation provides confirmation of the uptrend’s strength and sustainability," Turnquist and Buchbinder wrote. "When participation in the advance is limited—as is the case for 2023 thus far—vulnerabilities emerge as the weight of the market’s advance falls on the shoulders of a limited number of stocks."

Michael Landsberg, chief investment officer at Landsberg Bennett Private Wealth Management in Punta Gorda, Florida, agrees that the lack of market breadth has been 'misleading' in terms of the S&P 500's year-to-date gains, and is advising clients to look at defensive sectors beyond the tech space, including consumer staples, healthcare and utilities.

"We believe we are in the midst of a bear market rally and that the bear market is not over yet," Landsberg said. "The lack of market breadth, coupled with the past two quarters in a row of decelerating earnings, means there is still more downside risk ahead."

That view is largely echoed by Robert Schein, chief investment officer at Blanke Schein Wealth Management in Palm Desert, California, who argues that narrow breadth and Big Tech dominance is not a sustainable driver for a healthy bull market.

"We need the participation of other sectors," he said. "Investors should focus on actively diversifying their portfolios, with exposure to multiple sectors of the S&P and a variety of asset classes allows for better risk management in an environment where uncertainty abounds."

Data from Refinitv suggests consumer discretionary, staples, financials and industrials will be the second quarter earnings growth leaders, although overall S&P 500 profits are forecast to fall 5.4% from last year to a share-weighted $442 billion.

We expect any summertime strength to be short-lived with downside pressure on stocks returning in the fall, as the market starts to price-in lower earnings estimates," Schein said. "While we are not expecting a retest of the October 2022 lows, we could see the S&P 500 dip below 4,000 in the final few months of the year."
