In the video below, Fool analyst Austin Smith takes a look at three winners from 2012.

At the very top of Austin's list: banks, tech, and Fools.

Banks were the most hated sector of the market in early 2012. Then, they soared. Bank of America (BAC 3.35%) was up 100% in 2012. Citigroup, up 40%. Wells Fargo, up 23% and JPMorgan Chase, up 30%.

This came after headwinds from the London Whale, lawsuits, consumer protection, the fiscal cliff, and Dodd-Frank, Austin says.

Tech also fared well. The Nasdaq 100 was up 15%, almost double the Dow Jones Industrial Average (^DJI 0.56%) for the year.

The index has a market-cap weighting like the Dow, but can count Apple (AAPL -1.22%) in its midst. It also has rockstar stocks like Sirius XM, eBay, Amazon.com, and priceline.com, which all had a great year.

Lastly, Fools -- those who took the reins of their own investments -- were also winners, Austin says. Hedge funds underperformed again last year, up only an average 6% in 2012. Meanwhile, nearly two-thirds of both large-cap and small-cap managers underperformed their respective indexes.

What happened in 2012 is not guaranteed to repeat in 2013. But Austin sees all three of these trends continuing through the year ahead.
