Weekly Market Summary: Underlying Fundamentals Remain The Same

 | Oct 26, 2014 12:51AM ET

While equities have recently become volatile, the underlying fundamentals have not changed.

Companies are nearly halfway through their 3Q reporting period. Since the end of 2013, earnings have grown about 6% while sales have grown less than half that (3%). That means margins have continued to expand, by about 20bp.

That 6% growth in earnings is equal to the change in SPX year to date. So earnings multiples are no longer driving the market higher as in prior years. Instead, the market is being driven, equally, by sales growth and margin expansion.

Coming in to 2014, many believed that higher wages and interest costs would begin to erode margins. That hasn't happened. But margins do appear to be flattening. 3Q margins are tracking 20bp lower than 2Q. That's noteworthy as the margins for small cap companies already started to decline last quarter (chart ).
