Asset Allocation Update: First hot days, first warning signs on the stock markets

The first hot days heralded the arrival of summer, and the stock markets are already signalling a risk of overheating. We therefore reduced our equity exposure slightly in mid-May and are now only overweight in emerging markets.

What adjustments have we made to the portfolios?

We do not see a dot-com bubble 2.0 and remain constructive on tech shares. However, following the massive rally (+30% since April), we have taken some profits. Semiconductor stocks in particular appear heavily overbought, and a sector rotation in the coming weeks seems likely.

Bonds: Excessive rise in yields

The Strait of Hormuz has remained closed for nearly three months, and the oil price continues to hover around USD 100. As US inflation figures have come in higher than expected, the bond market has panicked, and yields have risen sharply worldwide. At the same time, interest rate hikes by central banks have been priced in. This may well be the case for the European Central Bank (ECB), but we do not foresee any interest rate hikes from the US Federal Reserve (Fed) this year and expect a reversal. Generally speaking, we find government bonds attractive given such high real yields – for example, over 2% on 10-year US government bonds – and remain overweight despite losses in May. Bond yields are in our opinion likely to fall again over the coming months.

Equities: Positive outlook despite short-term hurdles

Corporate earnings remain strong, and AI chip manufacturer Nvidia has once again delivered a positive surprise. Combined with robust economic data in the US, this should continue to favour equities. However, following an extremely strong rally in tech stocks, equities are overbought; accordingly, our sentiment indicators point to euphoria and are producing sell signals. We have therefore reduced our equity overweight slightly once again and are now only overweight in emerging markets, which remain attractively valued thanks to strong earnings growth in the tech sector and momentum. That said, market breadth in emerging markets is also weak, prompting us to take some profits there as well.

Alternative investments: Currently mostly on the sidelines

After being relatively active in gold and commodities in recent years, we are maintaining a neutral weighting in both asset classes. Gold appears to have lost some of its momentum, and we are waiting for a better entry point. As for commodities, whilst we expect oil prices to fall, the risk remains high due to the war in Iran. The risk-return ratio does not yet seem attractive enough to warrant an underweight position. Catastrophe bonds (cat bonds), on the other hand, are now becoming interesting: The hurricane season is about to begin, marking the most volatile period for this asset class. We continue to view the risk premium as attractive.

Outlook for the EuroStoxx50

We are cautious regarding the EuroStoxx50 Index. On the one hand, earnings growth is not as strong as in the US; on the other hand, the economic headwinds caused by rising energy prices in the eurozone are significantly greater than in the US. Leading indicators are already pointing to significantly weaker growth in the eurozone. Interest rate hikes by the ECB would not be helpful here either.
