On this episode of the AJ Bell Money & Markets podcast Dan Coatsworth and Danni Hewson dig through a bumper crop of Christmas trading updates from UK retailers including Tesco, Marks & Spencer and Sainsbury’s and they discuss the ongoing expansion of Greggs. After the discovery of loose bolts following a mid-flight blowout which saw a door pop off an Alaskan Airlines plane mid-flight, shares in Boeing and some of its suppliers have understandably been impacted as the FAA grounds the planes for further investigation. Danni considers the implications. Dan examines Terry Smith’s latest shareholder letter for the popular Fundsmith Equity Fund, and he also talks through ways benefit from higher interest rates in your Stocks and Shares ISA without having to switch out to a cash account. Plus, it may have started with a fake tweet, but the SEC has given the go-ahead to Bitcoin ETFs with some huge names like BlackRock and Fidelity about to jump in after what’s being called a watershed moment for cryptocurrency. Our special guest this week is Iain Cunningham from asset manager Ninety One who explains why China might still be of interest to investors wanting Asia exposure, despite slowing economic growth and tighter corporate regulation.
