What Martin Lewis Stock and Shares ISAs Say for 2025
Investing for 5 to 10 years (or more) is ideal with Stocks and Shares ISAs because short term returns can be impacted by market volatility. As with Cash ISAs, there can be an appreciation in the investment, but there is also a risk of depreciation, which means capital at risk. Unlike Cash ISAs, investments can rise or fall.
Lewis shares his views on the importance of low fees due to their erosion effect on profits over a sustained duration. Risk mitigation also necess spreading investments over different asset classes such as funds, bonds and stocks.
For quick access to funds, Cash ISAs are a safe option, but for sustained growth, Stocks and Shares ISAs provide better investment returns.
