My strategy
This is my strategy at this point in time. It will change over time as I learn new techniques and other strategies to improve my trading. Please keep in mind that I'm the United States and trade only with our markets. My style may not be applicable to other markets outside the United States.
As many of you know, the US releases quarterly earnings reports. Most companies release them in the months of January, April, July, and October. Because the US markets drops the most during the months of September-October and March-April, I do most of my buying in October (with the intent to sell before the end of December) and April (with the intent to sell before the end of June). I have noticed a pattern where most of my losses occurred in the first quarter (January-March) and I no longer trade during that quarter. The summer quarter (July - September) tends to be flat for me overall, so now I only trade in the second and fourth quarter.
I use stock screeners from different sites to find the stocks I want to trade. Here's one site I like to use.

After the second week of October or April, when the reports start showing up, I search with a screener using these parameters.
Debt/Equity ratio of 0.3 or less
Gross Profit margin of 10% or more
Return on Equity of 10% or more
P/E ration of 15 or less
Earnings per share (12 month) of $1 or more
Now I'll be given a huge list of potential stocks, but most of them show financial numbers from the previous quarter. I must weed through them to find the ones that are current.
Once I have a list of stocks with newly published quarterly reports, I look at everything else I can find about them.
Volume - I look at trade volume because if a stock isn't trading a few thousand shares every day, it's frustrating to buy and sell.
Insider Trading - If the insiders are selling, I usually avoid the stock because they're jumping ship. The only exception I'll allow is if there was a phenomenal spike in it's chart that the insiders took advantage of.
Chart volatility - Too obvious to explain. Well, for those of you new to swing trading, a chart with a flat line is ugly to a swing trader. Also, a chart where the stock is at it's peak or falling isn't attractive. I wait until it appears to have bottomed out or is just beginning it's recovery.
Recent News - To try and avoid any nasty surprises.
WFT is the only stock I have that does not fit my parameters. It's chart history is what I'm basing my decision on. Hopefully this won't be my bad choice that I have to bail out on, but it's possible and I make at least two bad stock choices each year.
