I have a 40 year background in accounting and finance at a number of public and private companies in increasingly responsible positions and have been a CFO for the last 20 years. My background in preparing financial statements, reporting to the Securities and Exchange Commission and having been involved in a number of company sales and purchases are invaluable tools in reading and understanding public company financial statements and their valuations.

# CSI Update-May 2021

2021 has been a barnburner for me so far. I am up 40.6% compared to the DOW which is up 12.8% and NASDAQ which is up 6.7%. May was a down month for NASDAQ but up for the DOW and down slightly for me (.4%). I didn’t sell anything in May, but I bought a few stocks.

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

The cost to subscribe is $50 a month for individuals, with a 100 subscriber limit. First-time subscribers can purchase a 3 month subscription for $100. I am not trying to get rich by having thousands of subscribers. I do this for self-discipline in my investing, so I am accountable to someone besides myself, which helps keep me focused.

Through May, 2021, I have averaged a 51% gain on the 58 stocks I have sold (54 winners and 4 losers) in my private portfolio since January 1, 2016. Fourteen of the 58 stocks have had buy-out offers, including two in 2016, six in 2017, two in 2018, none in 2019, two in 2020 and two so far in 2021.

My total portfolio was up 30.6% in 2020 and 72.8% in 2019.I took profit in almost the entire gains and banked it in cash.

We stopped publishing our free weekly CSI Blog after 10 years of publishing at the end of 2015. We closed out all of our remaining stock positions on the Blog in February 2021. Since inception in 2006, we had 73 winners, 20 losers for a 78.5% win-rate with an average gain of 38.9%.

We stopped publishing our free weekly CSI Blog after 10 years of publishing at the end of 2015. We are following our 2 remaining open positions until the end.

Through January, 2021, I have averaged a 46.8% gain on the 51 stocks I have sold (48 winners and 3 losers) in my private portfolio since January 1, 2016. Twelve of the 51 stocks have had buy-out offers, including six in 2017 and two in 2018, none in 2019 and two in 2020.

2021 has been a barnburner for me. I am up 19.6% compared to the DOW which is down 2%, NASDAQ which is up 1.4%.

**Prior Valuation $14.48 **

# Private Portfolio Update-ZAGG

Well I got another buy-out in 2020. ZAGG got an offer for up to $4.45 a share on Friday. That’s the good news. I sold my shares for a 43% loss. Fortunately I only had a small position.
