With the FTSE 100 hitting a new all-time high last week, some investors will be looking at their Stocks and Shares ISA with a sense of satisfaction. So, if someone had put £20k into a Stocks and Shares ISA at the low point of the last stock market crash in 2020, what would it be worth now? During a crash, some shares tumble in value for no good reason – but others fall because they were previously overpriced. So a £20k Stocks and Shares ISA invested in it back then now ought to be worth around £38,200. One I recently added back into my Stocks and Shares ISA is Henderson Far East Income (LSE: HFEL).
