Equity markets advanced on Monday, setting the S&P 500 up for an 8th consecutive week of gains. The move took the index up about 0.75% at the session's high to set a new multi-year high just shy of the current all-time high. Because the market continues to show resilience and momentum in the face of high interest rates and inflation, it should be expected to continue higher. The question is what the market will do once the all-time high is reached.

The primary market-moving event for the week is the PCE price index, due on Friday. The index is expected to confirm slowing inflation by posting the lowest pace in three years since the inflation surge began. The risk now is that inflation will cool faster than expected and lead the market to another extreme, an extreme in which disinflation and deflation lead to recession. Assuming the data is as expected, Santa Claus should come to town for the traditional Santa Claus Rally.
