WHILE the St Leger Day proverb to sell in May has been debunked by market experts, there are some months that are statistically unluckier than others.
June and September are the worst months of the year for returns, according to analysis of the FTSE All Share by Hargreaves Lansdown.
June is the only month that has posted negative returns more often than positive returns over the past 30 years, with the market falling by 0.7 per cent on average.
The market has fallen by 0.9 per cent on average in September, although it has made positive ground 50 per cent of the time.
Research shows October is the most "crashy" month, with the collapse of Lehman Brothers prompting the UK stock market to fall 12 per cent in October 2008, while in the eponymous crash of 1987, 27 per cent was wiped off the stock market.
Aside from these meltdowns, October is generally a decent month to invest, with returns being positive 70 per cent of the time and average growth of 0.6 per cent.
One seasonal effect that does gain support from historical stock market data is the Santa Rally. The research shows December is the best month for investing, offering positive returns 83 per cent of the time and seeing investors typically bank a profit of 2.5 per cent in just 31 days.
Laith Khalaf, senior analyst at Hargreaves Lansdown, said: "If every month were like December, the stock market could be expected to return a phenomenal 34 per cent a year."
