Slightly off topic : the inelastic markets theory21 Sep 2025 22:54
If you're puzzled as to why there are so many anomalies in UK stock market pricing, (eg Gamma?), there's an article in the FT about the inelastic markets theory, which is gaining ground. Basically, the stock market keeps marching higher, almost impervious to bad news: the gush of money into cheap, mindless passive investment strategies such as ETFs, especially those investing in fashionable markets such as the S and P 500. The efficient markets theory is being increasingly doubted, so that for example anomalies regarding pricing are no longer necessarily corrected.
