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 I 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.

Through April 30, 2020, I have averaged a 41.7% gain on the 39 stocks I have sold (37 winners and 2 small losers) in my private portfolio since January 1, 2016. Nine of the 37 stocks have had buy-out offers, including six in 2017 and two in 2018. But none in 2019 or 2020-yet. My total portfolio was up 72.8% in 2019.

The virus hammered all of my stocks in March but there was a little rebound in April.
