Another significant move in the S&P 500 marks a number of breakthroughs this year, with the index having made 34 record highs already. Whether this can continue, however, is uncertain, with the market increasingly driven by tech companies like Alphabet, Amazon and Apple.
While the broad market has returned just over 11% this year, the S&P Information Technology sector has returned more than 25%.
Investors have been willing to pay up for the growth offered by technology stocks, perceiving it to be in scarce supply elsewhere. But, if expectations around technology disappoint, or competition authorities look more closely at the sector, the hype could disappear quickly.
Investors who still want to allocate to the US might prefer to add to areas which have underperformed in recent months. If the equity market continues to do well, or if growth surprises to the upside, then this year's laggards (like oil equities) should have their day in the sun. But if the outlook becomes more challenging, investors will probably sell what they are overweight already, i.e. those large tech companies where growth increasingly comes at a premium.
