We stopped publishing our free weekly CSI Blog after 10 years of publishing at the end of 2015. We are following our 3 remaining open positions until the end.

In late 2015 we started offering a paid subscription service which is similar to the Blog, but we tell you exactly what stocks we bought and why—and sold every day, with a weekly summary of activity, open positions, how many shares we own and their valuations.

I have averaged a 40% gain on the 32 stocks I have sold (30 winners and 2 small losers) in my private portfolio since January 1, 2016. Nine of the 28 stocks have had buy-out offers, including six in 2017 and two in 2018. None in 2019—yet.

If you are interested in becoming one of our private paid subscribers, please e-mail me at daveosowski@gmail.com.

No news on our three remaining stocks.

AVID has continued to move up and is now up 86% this year..

ATEC is up 60% this year, but still is down 40% lifetime.

SYNC, one of our most frustrating stocks ever has done nothing. Activist investors, a new CFO with M&A experience and still trading at only 27% of our valuation.
