This week's Wall Street Transcript Interview is with Covestor member Michael Arold, aka sunshine_micha.  Michael works in marketing for a software company and trades part time on the side. You can read his daily market thoughts on his blog, Sunshine Trader.

Michael is a short term swing trader, holding his positions on average between two and fifteen days. He focuses on technical analysis, to not only evaluate his positions on the fly but also the overall market.

In his interview Michael discusses how he considers a concentrated portfolio to be more effective with his trading style than a diverse one. With swing trading he tends to focus on what is in trend right now, rather than worrying about the overall market. "There is always a bull and a bear market somewhere and that's where I'm playing." Says Michael.

Michael tracks his portfolio on Covestor, and promotes disciplined investing as a key to success. You
can find the interview - as always - on the top right hand side of his fact sheet.
