Stockmarket has see-sawed lately amid a flare-up in trade tensions, but remains near its all-time high. The surge, fuelled by enthusiasm around artificial intelligence, has drawn comparisons to the exuberance of the late 1990s that culminated in the dotcom crash of 2000. Though technological innovation is undeniably reshaping industries and increasing productivity, investors have good reasons to worry that the current rally may be setting the stage for another painful market correction. The consequences of such a crash, however, could be far more severe and global in scope than those felt a quarter of a century ago.

The Bank of Spain has warned that the current overvaluation of major US technology companies could trigger sharp corrections in financial markets if profit expectations are not met, particularly in the development of artificial intelligence. The high concentration of investment in these companies, such as Nvidia, Microsoft, and Alphabet (Google's parent company), would increase the likelihood that any shocks related to their business could have systemic effects worldwide.

The world of finance is beginning to dwarf planet Earth. This was stated by Harvard historian Niall Ferguson in his book. The triumph of money (Debate, 2011, updated in 2024). Over the years, this trend has solidified, and the financial economy is outpacing the real world. A prime example is the large technology companies in the United States, especially those most closely related to artificial intelligence (AI). These are companies that have surpassed historic price levels and are beginning to raise alarms not only about the existence of a bubble, which no one doubts, but also about its potential bursting.

Barcelona and Madrid have been suffering from a housing bubble for two years, according to a new study. The causes include several factors, from population growth due to the arrival of immigration and the lack of public and private housing construction to the cheapening of credit and the entry of speculative investors.

A few days ago, returning home on the AP-7, we were stopped by long queues before we drove through a police checkpoint a vehicle at a time. The checkpoint's aim, I imagine, was to find out people who were travelling with those other than their cohabitation bubble. In a pandemic situation everything is very strange, but I felt very uncomfortable, and I thought that the concept of cohabitation bubble was retro and that it doesn't respond to today's personal relationships and families.
