NEW YORK (ETF Expert) --Broad-based stock and bond ETFs have struggled throughout the final month of the secondnd quarter. However, some folks may have found a bit of refuge in the banking sector.

The momentum play in banking appears rational. Yields on long-dated bond maturities have been skyrocketing while shorter-term maturities have not moved quite so dramatically. When the "yield curve" steepens in this manner, one might assume that banks will profit from the larger spread between short- and long-term interest rates; that is, they may borrow at ultra-low rates as well as lend out at much higher rates to businesses and consumers.

TheStreet's

Jim Cramer is already touting the technical strength of funds like

KBW Regional Banking

(KRE) - Get Report

and

SPDR KBW Bank

(KBE) - Get Report

. Looking at the current yield curve while ignoring future economic probabilities, however, may bite the momentum player in the backside.

If economic data sour in the months ahead (and I believe that it will), the markets will embrace the notion that the

Federal Reserve

cannot justify tapering its easing program. Does anyone really believe that the economy is

currently

capable of standing on its own? You can almost here Howard Cosell saying, "Down go Treasury yields! Down go Treasury yields!"

By way of review, Europe's endless recession shows little signs of improvement; higher yields in the region are already hindering the recovery hopes of French, Italian and Spanish citizens. China's manufacturing segment is contracting at the same time that its leaders have responsibly elected to refrain from easing with reckless abandon.

What's more, corporate earnings may already be in trouble, as negative pre-announcements by

S&P 500

corporations are at their highest levels in 17 years (N/P is approximately 7.0).

Personally, I would hold off on over-weighting the financial sector. The easy money via the steepening of the yield curve has likely been "banked" already. The time to overweight financials on the steepening theme was at the start of May, rather than at the end of June, as evidenced by

In my estimation, there will be a better opportunity to invest in equities that come in a wide variety of shapes and sizes. Nevertheless, if you're going to dollar cost average into stocks at this moment, dividend growth stocks and "non-utility non-cyclicals" are better for a summertime of 1%-2% price swings.

Vanguard Dividend Growth

,

Market Vectors Retail

(RTH) - Get Report

and

Market Vectors Pharmaceuticals

(PPH) - Get Report

are all on my radar screen.

Meanwhile, a "contrarian trader" might even be so bold as to think in terms of the yield curve flattening due to increasing risks of recession; he/she might choose to investigate

(FLAT) - Get Report

. It may not be realistic for my conservative clients, but active traders may choose to play the "contrary-to-popular-wisdom" angle.
