Almost everyone is happy when markets trend higher. But unfortunately, this is almost never the case.

Each week at Stockpickr, we look for short-term catalysts and snapback plays that could move higher no matter what the market does, and I present these picks each Monday morning in Rocket Stocks portfolio.

With more than 8,000 publicly traded companies, there are bound to be a handful of stocks that move higher whether the market is up huge or down huge.

These picks are for the short term, meaning that investors who buy these stocks, based on these catalysts, should hold them for no longer than one or two days (or until the catalyst has triggered). However, selling stocks and locking in gains is one of the toughest things for investors to do; that is why I started writing this weekly update on Wednesday mornings.

I would sell First Solar ( FSLR), which rose 6% as oil continued its climb higher. Alternative-energy stocks seem to get their groove at the moment oil touches $80. The business models make it conducive for such companies to be profitable.

I would also get out of FreightCar America ( RAIL), which is also up 6%. Nothing changed here fundamentally; we just caught it perfectly. The freight car company still has a ton of cash on the balance sheets, a high short position and an interesting business model. It's definitely one to keep on the watch list.

I'd consider selling Linketone ( LTON). The telecom company has enjoyed a 10% upward move. While still trading at near cash flow models, there seems to be little fundamental evidence to suggest small cap Chinese stocks should be rallying so much. Let's take our profit and walk away.

And finally I would grab a sell ticket for Kohl's ( KSS). The department store was up on Tuesday despite weak economic reports. Kohl's unveiled a new five-year strategic plan to increase store count by 67%. Wall Street loved this and sent shares higher 2%.

This week's update also includes one additional stock. Let's take a look.

Down some 35% in 10 days, Acxiom ( ACXM) announced that Silver Lake Partners had cancelled its $2.3 billion acquisition of the company. This news sent shares of Acxiom plummeting near its 52-week low, which might have created a great buying opportunity. Acxiom specializes in data management and, according to EMC ( EMC), that business is booming. Having said that, ACXM is certainly no EMC but it does have some similarities.

Silver Lake Partners is not stupid; they saw value here but pulled out at the last moment. Odds are the offer was too high. Let's pick up some shares on the cheap.
