For Posterity

I haven’t updated since sharing the news of Dave’s passing. I had several friends of ours, who were fellow engineers and developers, try to revive Dave’s dream with his portfolio software. Unfortunately, the task has proven insurmountable and we’ve decided to step away from the project now.

So, while the software will never see the light of day, I have decided to keep Dave’s blog up. For one obvious reason, I don’t have the heart to take it down. For another, I think many of his posts were intelligent and insightful, and I hope people will continue to find interest and meaning in them.

Thank you to everyone who supported his vision.


Moving Forward

For those of you who may have been following the Sigma 1 blog for the past few years, you may be surprised by the sudden rebranding and name change. A lot has happened in 2016 that has precipitated these changes.

Firstly, I am sad to inform you that the founder of Sigma 1, Dave Balhiser, passed away in January of 2016. Secondly, I would like to introduce myself. I am Gabi Endress-Balhiser, and I was Dave’s wife and partner. I have decided to not let the work my husband put into his portfolio optimization product go to waste, so I have partnered with some of his team and we are working on continuing to develop the tool and bring it to market, hopefully sometime in 2017.

Admittedly it has been a difficult year. Dave’s brilliant mind and kind heart are missed by many. I watched him put hundreds of hours into developing this software. It was his passion and he truly believed it was revolutionary. The back-end of the product was rock solid before he passed, and the only missing element was a front-end to make it user-friendly. I have a background in usability and I have managed teams of developers in the past, so I am hoping I can help my husband’s dream come to fruition.

I am admittedly not a Quant by any stretch of the imagination, but if there is an interest I may invite guest bloggers to contribute to this site as we continue to move forward.

Thank you to everyone who supported my husband in his quest to build a revolutionary portfolio optimization software. I hope I will have your support along the way as well.
