Copy trading is a fast-growing trend, where investors discuss portfolios and markets, potentially influencing investment decisions. Copy trading takes this a step further, as investors mirror the portfolio and trades of another user of the platform.
In this episode of Which? Money, senior researcher Megan Thomas explains how copy trading works, how risky it can be, and how certain trading platforms are becoming destinations for those who think it’s an easy way to increase the value of an investment portfolio.
Megan shares the result of her experiment, which saw novice investors try out social trading and copy trading platforms for the first time, to track how drawn users were to investors who already had tens of thousands of other investors following their every move.
Plus, Simon Weidenholzer, professor of economics at the University of Essex, talks us through the history of the trend, and describes how giving people the option to directly copy others can lead to a significant increase in risk taking.

Switching mobile networks can seem like a hassle, but it’s easier than ever to move to a new provider and potentially save hundreds of pounds per year.
In this episode of Which? Shorts, we reveal the results of our survey of consumers to find out which mobile networks are the best on price, customer service and more.
We explain how smaller, virtual networks actually piggyback off the infrastructure of one of the Big Four networks - EE, O2, Three and Vodafone - meaning you can get the same network coverage and signal at a fraction of the price.
This episode is read by Rob Lilley-Jones and is based on an article written by Adam Snook, originally published in the May 2026 issue of Which? magazine.

12.2m people are on track to face poverty in retirement, meaning you won’t have enough money to live the most basic standard of living once you stop working.
In this episode of Which? Money, Scottish Widows’ head of pension policy Pete Glancy joins us to talk us through his research that explains why so many UK adults aren’t saving enough to live comfortably in later life.
Pete shares his insight into what he thinks needs to change to help more of us save more money into our workplace pensions, and explains how the reestablishment of the Pension Commission may lead to policy changes that benefit employees.
