It really does depend on your starting point. Investors who purchased in 2016 when the share price was below $60 (for a while below $50) have enjoyed not only good dividends but a modest capital gain - annualised returns around 10% pa (+/- depending on your exact purchase price). People who purchased at higher prices would have done less well.
At 6.2% I'm a happy holder - noting the strength of the balance sheet (they have been returning excess capital through buy-backs in recent years) which suggests that the current dividend could be maintained in a modest downturn. I also note that post-results, Macquarie has downgrade HSBC to underperform with a $57.20 target.
