Why ChatGPT & Co. Are Blind When It Comes to Stocks: Training Cutoff and Search Bias

Anyone analyzing a stock today often asks ChatGPT, Claude or Perplexity first. That is understandable, since the models have become remarkably good in a short time. Still, this is exactly where the greatest risk lies. The problem has little to do with the AI getting its calculations wrong. The AI answers convincingly while something crucial is missing. Two mechanisms are responsible for this: the training cutoff and the search bias.

What does KI say about the exploratory talks?

While the planned 500 billion investment offensive by the CDU, CSU and SPD promises economic impetus in the short term, Germany is in danger of sinking into a debt trap in the long term and missing out on structural reforms. Although the coalition compromise cleverly caters to different groups of voters, it postpones the really difficult decisions to the future - with potentially serious consequences for competitiveness, demographic development and financial stability.

The Fed gets room, the ECB loses it



US employers added 29,000 jobs in September, about a third of forecasts, and earlier months were revised lower. Lower immigration has made weak payrolls a poor signal on their own. Unemployment rising to 4.2% is harder to dismiss, because it points to real slack. Wage growth slowed to 3.0%. Philip Jefferson and John Williams of the Fed saw no urgency to hike, and markets put late-October hike odds near one in four. Long Treasury yields stayed above 5%, so…More …

The Fed got room, long bonds ignored it



On Monday markets priced close to a 70% chance of a late-October Fed hike. By the weekend that had fallen to about one in four. Consumer confidence dropped to its lowest since 2014, job openings fell by about 256,000, August PCE inflation came in softer, and September payrolls rose by only 29,000. Lower immigration makes weak hiring a poor signal on its own. Unemployment rising to 4.2%, with wage growth slowing to 3.0%, is harder to dismiss because it …More …

London and Paris pay more to borrow



Britain's 30-year gilt yield touched 6.03% on Thursday, the highest since January 1998, and the 10-year reached 5.51%, the highest since July 2007. Much of this comes from the global bond sell-off, with the US 10-year near 5.3% and Brent back above $100. The British part is the budget on 28 October, which has to reassure buyers who can now afford to be choosy. Long gilt yields set the discount rate for UK dividend stocks and feed into mortgage pricing.

F…More …

Hike risk moves to Frankfurt



September inflation rose again in the euro area's largest economies. Germany's harmonised rate reached 3.3%, its highest since December 2023. France's jumped to 3.4% from 2.6%, and Italy's preliminary figure came in above 4%. Energy costs from the Iran war are now reaching shop prices, and markets priced in more ECB tightening. All three readings now run well above the ECB's 2.5% deposit rate.

In the US, August PCE inflation rose less than expected, July was re…More …

Reasons for lower yields, and higher yields



Tuesday gave bond buyers several reasons to push yields lower. The Conference Board's consumer confidence index fell to its lowest since 2014, and August job openings dropped by about 256,000 to 7.08 million. Brent fell more than 2% as Saudi Arabia resumed loadings through its repaired East–West bypass. New York Fed President John Williams saw no urgency for another hike, though Governor Michael Barr said more may be needed. October hike odds fell…More …

Rate pressure reached the short end



Monday was the first full session after Trump rejected Iran's seven-day ceasefire offer, and Brent moved back towards $100. Last week the selling sat mainly in long bonds. On Monday it spread to the two-year Treasury, which tracks expectations for Fed policy. That yield, near 4.9%, is heading for its largest monthly rise since February 2023. Futures now put the chance of an October hike close to 70%.

The two-year matters for stocks because it sets what c…More …

The bypass now needs guarding



Iran said it is waiting for a clear US answer and will not ease its Hormuz terms after Trump rejected its proposal. Since Friday, Saudi Arabia has intercepted Houthi drones near Riyadh and missiles near Khamis Mushait, with alerts in Abha and in Jazan, which has a large refinery. France has committed soldiers, radar and air defences to Yanbu. That is the Red Sea port where the East–West pipeline delivers crude that avoids Hormuz. The route meant to reduce Hormu…More …

Two sets of buyers, one Friday



The US 10-year yield briefly reached 5.23% on Friday, and Japan's 10-year touched 3.12%. The MOVE index rose about 30% over the week, its largest weekly jump since April 2025. The index tracks bond-market volatility, and a higher reading limits how much risk funds are allowed to carry. Futures priced roughly a 64% chance of an October Fed hike.

The S&P 500 still closed higher, and global equity funds took in $44.1bn during the week. That is the split describe…More …

The bond market did the tightening



Last week's decisions from the Fed, the Bank of England and the Bank of Japan set the frame. This week the long end of the bond market went further than any of them. The US 10-year yield crossed 5% and briefly touched 5.23% on Friday, its highest since 2007. Japan's 10-year reached 3.12%, the highest since 1996, and the German 10-year held near levels last seen around 2009. On the worst day, 10-year yields in the US, UK, France, Italy and Spain each rose ro…More …

Who paid for the good news



September flash composite PMIs came in above expectations in the euro area and the US, with survey detail crediting AI-related and defence work, and the OECD lifted its 2026 global growth forecast to 2.9%. The US employment and input-price components rose alongside output, which is the combination central banks dislike most.

The New York tape settled the interpretation within hours. Utilities fell close to 2% and real estate around 1.5%, while energy was the only…More …
