Welcome to December! Celebrations are coming… According to the seasonality patterns, you have nothing to fear anymore for the next few weeks since the Santa Rally will now take care of bringing your portfolios accumulated YTD returns, included an additional last mile boost, directly under your Christmas Tree. For that, you just need to believe that Jay Powell and his Fed’s elves will behave well on December 10th by cutting rates as most investors have requested in their letter to father Christmas.
Speaking about seasonality, I came across these statistics here below about S&P500 annual performances by presidential years. Apparently, the 2nd year of a Presidential mandate seems the worst. So, it is perhaps an element to consider -for seasonality believers at least- that goes somewhat against the crowd as many Wall Street houses have just released their rosy 2026 forecasts, which often call for another round of double-digit gains for the S&P500 by seeing good times rolling next year… Let’s already celebrate and be grateful for this year.

Economic calendar
Turning to the economic calendar, a busy week still awaits us despite the November job’s report won’t be released on Friday (it is postponed until December 16th, courtesy of the several weeks-long US government shutdown). We will get updated insights about economic activity through the releases of the global PMI for November as well as the US ISM indices (Monday for manufacturing and Wednesday for services), but also inflation via the delayed September US PCE deflator (Friday) and the Switzerland CPI for November and Euro Area flash CPI. Other noticeable economic data releases include the US ADP employment survey (Wednesday), the US jobless claims (Thursday) and the preliminary University of Michigan consumer sentiment for December on Friday.
While the Fed enters a blackout period ahead of 10-Dec FOMC decision, there will be -at the time of writing on Sunday evening- a speech by BoJ Governor Ueda on Monday. We may have therefore more clarity on whether the BoJ will hike in December or January, but I doubt… Anyway, I believe BoJ will move as soon as this month given (1) mounting pressures about JPY weakness and rising inflation and (2) the fact that BoJ likes to surprise when it acts (more bangs for their bucks)… so why waiting until January?
Finally, ending with the last few earnings to be released, tech and consumer companies will dominate the headlines this week with the results of Crowdstrike, Marvell, Salesforce or Snowflake within IT, as well as those of Inditex, Macy’s and Kroger for consumers, among others.
