UBS has told clients that UK equities are better placed than at any point this year "without being in control", comparing the market to England's 4-0 half-time lead over France in the recent World Cup third-place play-off.
France's second-half response meant the result was not secure until the closing stages.
Strategists Sutanya Chedda and Gerry Fowler said the same caution applies to Britain, where the economic backdrop has turned back to recovery and valuations remain supportive, but the fundamentals have not put the result beyond doubt.
Recovery, but "not yet an all-clear"
The bank's regime model now assigns a 52.9% probability to recovery and 23.5% to expansion, with the chance of a downturn down to 16.3%.
Recovery regimes have historically delivered positive FTSE 100 returns, though the relative advantage for the FTSE 250 has been marginal.
UBS sees upside risk to its second-quarter GDP forecast, but inflation is expected to rise again and the bank does not expect a Bank of England cut until 2027.
That combination favours companies able to absorb higher rates, and makes the distinction between genuine earnings defensiveness and share-price defensiveness increasingly important.
Earnings are the weak link
The improved backdrop has not fed through to earnings breadth, which the UBS pair identify as the weakest of the four pillars.
Forecasts for this year and next fell 1.0% and 1.2% over the month, although they remain 9.7% and 6.5% above where they started the year.
Four-week revision breadth in Britain is negative at -3.5%, against +3.6% in Europe.
The split by size is sharper still, with large-cap breadth at +4.6% and small and mid-cap breadth at -7.2%.
Energy, mining and banks still account for a disproportionate share of expected growth this year.
Cheap, but not uniformly
The UK discount survives adjustments for sector composition, profitability and quality, and cheapness is broadening below the index.
Some 56% of FTSE 100 constituents and 76% of FTSE 250 constituents trade below their ten-year average relative multiple.
The combined dividend and net buyback yield of 4.3% remains attractive against global peers, though UBS cautions that high yield is only defensive where free cash flow covers the distribution.
Sentiment is the most improved pillar, but fund flows remain negative and crowding is still elevated relative to Europe.
With return dispersion at the 92nd percentile, UBS concludes this is a stock-selection market rather than a case for buying UK 'beta' indiscriminately.
