NEW YORK (ETF Expert) --There's a tendency in the financial media to wrap up calendar years with a focus on the "winners" and "losers." Inevitably, a large number of unsophisticated investors will allocate money to the so-called best performers, while avoiding any commitment to the underachievers.

Herein lies one of the biggest mistakes that ETF enthusiasts make. Specifically, they view success through a prism of calendar-year data, ignoring genuine momentum found in relative strength or price ratios or even May-over-May performance. In fact, a calendar-year obsession has enormous potential to mislead.

Keep in mind, it's not uncommon for worst performers in one year to reverse course entirely. In 2011,

iShares MSCI Turkey

(TUR) - Get Report

lost a staggering -36.6%. In 2012? TUR was one of the best unleveraged ETF performers with an eye-popping 65.6% gain.

Recognizing that 2012 "losers" may reverse course in 2013, I identified three ETF spaces that may do just that. Each of the asset areas discussed below under-performed broader large-cap equity benchmarks (i.e.,

S&P 500

, MSCI All World) on a year-over-year basis. By the same token, each demonstrated greater relative strength than these benchmarks over the last five trading sessions.

1. Pipeline MLPs.

Whether aggregating individual companies via exchange-traded fund or exchange-traded note, pipeline master limited partnerships offer something that few investment types can: about a 5% or better yield with about a 5% average company growth rate.

Yet, 2012 was brutally unkind to the pipeline MLPs/energy sector due to falling demand, falling prices, regulatory fear/burden and fiscal cliff dividend tax uncertainty.

As recently as Dec. 30,

JP Morgan Alerian MLP ETN

(AMJ) - Get Report

was below a 200-day trendline. A few trading days later (Jan. 3), with the "cliff resolution" removing dividend tax uncertainty, things look very different.

This is not to suggest that everything is hunky-dory for the asset class. There is environmental resistance to allowing the Keystone Pipeline to be built. The White House has hinted at additional tax reform in the debt ceiling debate, which may reintroduce uncertainty to the asset class and its structure.

Even a 10-year yield that manages to move another 50 basis points higher could threaten a favorable spread (300 basis points). Nevertheless, I would still be intrigued by a minor pullback in funds like

Credit Suisse MLP 30

(MLPN)

and

UBS Alerian MLP Infrastructure

(MLPI) - Get Report

.

2. Strategic Metals and Industrial Metals.

Year-over-year,

SPDR Metals and Mining

(XME) - Get Report

is down -5%. For believers in hard assets, that's a particularly jagged pill to swallow. And yet, ever since China announced a steadfast commitment to support 7.5% GDP going forward, accompanied by several months of manufacturing segment expansion, materials and metals have moved steadily higher.

In truth, China is more likely to grow at 8% and its factory sector hasn't been this strong since May of 2011. With the world's largest economy being the primary engine for global growth, and with demand for industrial/strategic metals surging, look for the possibility of enhanced capital appreciation.

Market Vectors Strategic Metals

(REMX) - Get Report

and

Market Vectors Steel

(SLX) - Get Report

are worthy of placing on your watch list.

3. Oil Equipment and Services.

At first glance, one might view this energy sub-sector in the same vein as Pipeline MLPs. However, the former is engaged primarily in helping other firms produce/acquire fossil fuels while the latter primarily deals with storage and transportation.

More importantly, oil equipment/services firms tend to be structured as traditional C corporations whereas

MLPs have favorable pass-through partnership structures with no corporate taxation.

Granted, that may sound like a mouthful. What's more, if the asset types were highly correlated, the differences might not mean a great deal. However, over the last six months,

iShares DJ Oil and Equipment Services

(IEZ) - Get Report

had an exceptionally low correlation coefficient (0.36) with JP Morgan Alerian. It follows that

energy stock advocates should still be looking at funds like iShares DJ Oil and Equipment Services,

Market Vectors Oil Services

(OIH) - Get Report

and

SPDR Oil Gas Equipment and Services

(XES) - Get Report
