I recently came across the International Business Times' list of the 10 greatest trades of all time. And what I saw surprised me.  You see, I thought I'd find Warren Buffett's buying of Geico or Coca-Cola -- or some of Peter Lynch's 10-bagger stocks like Fannie Mae or Taco Bell.

Both investors failed to make the cut.

The trades that did make the list, in hindsight, make sense because of how uniquely contrarian they were. And I think they could provide a key piece of advice that -- if you're like most investors -- you'd do well to implement today.

After I share these top trades with you, I'll share with you a unique solution for putting the lessons they offer into practice today.

Surprised? Five and a half of the most lucrative trades were bearish shorting plays. Only four and a half were long-only strategies -- though those typically took longer to pan out than the short calls. And most of the longs were concentrated sector bets.

Now I don't think this makes the case that shorting stocks, commodities, or sectors are on par with going long. After all, "shorting" and "hedging" can be risky strategies if you aren't fully aware of the risks involved.

But I do think this chart speaks to the fact that, if you're not using a variety of both bullish and bearish tactics in your portfolio, you're missing out on lucrative profits when the market dips, stays flat, or one sector takes off.

After all, these ten trades alone netted these men billions of dollars.

And it's something you can easily replicate yourself
With the exception of Paulson's shorting of subprime mortgages through credit default swaps and perhaps Soros' shorting of pound sterling, nearly all of these moves could have been made by an individual investor like you.

In fact, a colleague of mine here at the Fool, Jeff Fischer, is making similarly diverse bets using a mixture of stocks, options, and ETFs, by going both long and short. And he's been quite successful -- turning $1 million into over $1.4 million in just over two years.

He went long GrafTech International (NYSE: GTI) at the end of 2008, then again in 2009. It's the largest manufacturer of graphite electrodes, which are used to heat steel used for infrastructure and other construction by companies like Arcelor Mittal (NYSE: MT). Its technology also produces other metals and chemicals for big-tech names like Apple and MEMC Electronic Materials.

He's up 130% as management continued to execute in the midst of an industry downturn.

Jeff makes concentrated sectors bets as well. He recently bought shares of WisdomTree Emerging Markets Small-Cap Dividend ETF (NYSE: DGS). His thesis on this ETF is threefold: small caps outperform large caps by an average 2.1% per year, companies that pay dividends outperform those that don't, and emerging markets have outperformed U.S. stocks by 9% annually in recent years. Together, these three truisms should work in his favor -- and let the fund pocket 2.7% in dividends annually.

Lastly, Jeff dabbles in both bullish and bearish options strategies. One of his recent bold bets was to write naked calls on iPath S&P 500 Short-Term Futures (NYSE: VXX). He noticed how poorly this ETN tracks the VIX index, and thought investors could profit nicely from this lag. This investment couldn't have been more prescient -- he's up over 90% in less than two months!
