Several factors contribute to this strong seasonal performance:

1. Earnings Season Momentum – April is a key month for corporate earnings, with FTSE 100 companies benefiting from a post-first-quarter earnings boost.
2. Fiscal Year-End Flows – Many UK-based funds adjust portfolios at the end of the tax year in early April, often leading to a reallocation into equities.
3. Dividend Reinvestment – The FTSE 100 is a high-dividend-yielding index, and April typically sees dividend reinvestment flows that support stock prices.

This historical backdrop suggests that even in a challenging fiscal environment, the FTSE 100 could still find seasonal strength. One final piece of data to consider is the maximum drop during a profitable year of that same pattern. You can see below that the largest drop during a profitable year has been 6.88%. This can be extremely helpful to see what sort of maximum stop losses could be used. It is helpful to know that intra-period falls of up to 6.88% have still been seen in profitable years.

UK Fiscal Policy and Market Implications

The Spring Statement is shaping up to be a significant market event. Chancellor Rachel Reeves is under pressure to stabilize public finances while adhering to her self-imposed fiscal rules. Preliminary forecasts from the Office for Budget Responsibility (OBR) indicate that the UK may miss key fiscal targets, prompting the need for spending reductions. Reeves has already instructed government departments to model budget cuts of up to 11%, with welfare spending and green investment likely to be impacted.

Additionally, any hawkish shift from the Bank of England in response to persistent inflation risks could weigh on the FTSE 100, particularly on rate-sensitive sectors. However, the seasonal pattern is strong and driven by other important factors and has a high historical win rate.
