What sectors are poised to outperform as a result of a Barack Obama presidency? To find out, we turn to fund expert Jim Lowell who recent prepared a report highlighting the top ETFs based on each candidate.

In The Forbes ETF Trader, he offers several top picks including ETFs that are focused on biotechnology and medical research, industrials, clean environment and clean energy technologies.

"SPDR Biotech (ASE: XBI) seeks investment results that correspond to the price and yield performance of the S&P Biotechnology Select Industry Index which is made up of the biotechnology sector of the S&P Total Markets Index.

"It began trading in January 2006. The top ten holdings are Genentech, Amgen, Gilead Sciences, Celgene, Genzyme, Biogen Idec, Imclone, Cephalon, Vertex Pharmaceuticals, and Alexion Pharmaceuticals.

"Vanguard Industrials (NYSE: VIS) seeks investment results that correspond to the price and yield performance of the Morgan Stanley Capital International US Investable Market Industrials Index.

On tonight's Mad Money, Jim Cramer noted Borg Warner Inc. (NYSE: BWA) as a company that can actually win on the "green movement." This is an auto parts and power trains applications company, certainly not something that would normally be thought of as a "green investment." But the company is working on developing more environmentally friendly products, and currently has a $1.7 billion backlog and the orders are still accelerating. Before you follow Cramer blindly, you should know that this may be true that the company has "lower emission" parts than others, but it looks like he is out picking the auto parts players that are still standing and close to highs more than a true "green investment" pick.

Once again, there are safer ways (safe being relative to diversification only) to play alternative energy ("alt-en"). A few names I have looked at for exposure to alternative energy and that I feel better about are actually what I call the "alt-en" ETFs, and these may offer you a safer mix of companies since some of the holdings are diversified and have many different operations. The PowerShares WilderHill Clean Energy ETF (AMEX: PBW), PowerShares Cleantech ETF (AMEX: PZD), and PowerShares WilderHill Progressive Energy Portfolio (AMEX: PUW) will all give some alternative-energy sector exposure that won't as easily rip apart your wallet if you make the wrong pick. ETFs will not give you the upside potential of a single speculative play, but if you've been doing this long enough, you already know how painful picking the wrong name in the right sector can be. Alt-en ETFs give you exposure to the sector without the company-specific risk.

Tonight, Cramer continued his "going green" segment after changing his stance on alternative energy stocks last night.

One he really likes is First Solar (NASDAQ: FSLR), which can compete head to head with traditional power companies in the fairly near future; he's liked it since March and it's up 30% in that time. MEMC Electronics (NYSE: WFR) is the other one he likes because they make the silicon wafers for solar panels; this one is up 200% since Q3 2006 and he has been positive on this one all the way up because there is a silicon shortage and the company is well-positioned to capitalize on it. Cramer did say that these names are all up big big, so what you really want to do is look for these on pullbacks when they get cheaper.

There is a much safer way (safe is a "relative term" only) to invest in alternative energy, and you won't be risking it all in a single speculative name. A few names I have looked at for exposure to "Alt-En" and that I feel better about are actually what I call the "Alt-En" ETF's, and these may offer you a safer mix of companies since some of the holdings are actually diversified and have many different operations. The PowerShares WilderHill Clean Energy ETF (AMEX: PBW), PowerShares Cleantech ETF (AMEX: PZD), PowerShares WilderHill Progressive Energy Portfolio (AMEX: PUW) will all give some alternative energy sector exposure that won't as easily rip apart your wallet if you make the wrong pick.
