one of the best job descriptions I've read on working as an operations engineer. best two quotes: "If you don't grow, you'll fail." & "Think of it like any other fun and challenging job you've had -- now remove the margin for error." How true!

Portfolio Performance for September 2008

September came and went. October brought the perfect storm...I guess. Looking forward to October's portfolio performance in relation to the see how bad things really are. Until then...let's cover September's performance.

September's VAMI

September's ROI

As you can see, not a great month of performance. And while the downside doesn't feel greatest concern is the upside that will come. When it does...the portfolio will lag the market due to the relatively high level of cash. But, nothing we can do...but be patient and allow the system to do its job.

Last thing you want to do during turbulent times is hit the panic button. Or worse, try to figure this market out. You don't figure a hurricane out while you're in the middle of it. Don't buy a generator, food, and flood insurance during a hurricane. Those are things you buy prior. The only thing you can do when the storm hits is batten down the hatches and hope you prepared enough for the damage to come. After the storm is over...reassess what you did right and what was lacking. Oh, and clear those fallen trees from your portfolio.

On a side note...I've spent the weekend putting together a new office. I've bought several office pieces and trying to find the optimal setup. Once I've got everything moved in...I'll share some pics of the new digs.

Later trades,


What's an Outsider to do?

I avoid watching all news programs...especially related to the market and economy. Avoid reading newspapers and for the most part news bloggers. My one exception is Howard Lindzon. I read him for his take on the entrepreneurial spirit...but with it have to eat the occasional brussel sprout when he starts pawing at the market's ups and downs.

Same goes with people. Typically, talk very little about the market to others. And rarely hear more than a peep or two about the market from others in the water cooler discussions.

That is until now. This recent market debacle has really changed things. Howard is causing me to eat mucho brussel sprouts. My wife is hearing about the market on Dr. Phil & Oprah of all things. And even my programming bloggers are discussing the economy and the hoozy whatsits of the markets.

So, what's an outsider to do? Well, we should ask ourselves what a maverick would do and do that. Or watch these videos for inspiration...

If those don't make you laugh...just remember my fellow mavericks...this too shall pass.

Later Trades,

Python plotting interface to various backend plotting engines: Gnuplot, Matplotlib, Grace, Veusz, PyX, VTK, VisIt, OpenDX, and a few more. Seems like a fairly straight-forward interface. And choosing the backend used is a one-line import statement. Interesting.
