Copernicus Portfolio Review: 5 May 2025

May 5, 2025 By Lowell Herr Leave a Comment

As I write this blog the U.S. Stock Market is attempting to regain early Monday losses.  As long-time reader know, the Copernicus is an equities only portfolio.  The management model is to save and purchase S&P 500 ETFs.  Based on the current administration generated chaos I am moving toward a more conservative model.  I am […]

Huygens Portfolio Review: 13 May 2025

May 14, 2025 By Lowell Herr Leave a Comment

Huygens is one of two portfolios using an expanded Asset Allocation (AA) management model.  The other is the computer managed Schrodinger or Schwab’s Intelligent Portfolio.  Over the past month the Huygens lost a bit of ground to its benchmark, the AOR security.  Most likely the AOR is tilted a tad more toward equity holdings whereas […]

Schrodinger Portfolio Review: 16 May 2025

May 16, 2025 By Lowell Herr 1 Comment

Since the last review Schwab made a number of changes in the Schrodinger.  It is rare for such changes.  I suspect Schwab performed some tax harvesting.  One change was to add a municipal bond ETF, SCMB.  The percentage is so small it will not have much impact on the overall performance. Schrodinger Security Holdings Below […]

Einstein Portfolio Review: 21 May 2025

May 22, 2025 By Lowell Herr Leave a Comment

Einstein is one of several portfolios using a truncated Asset Allocation investing model.  This is a new and simplified approach in the hopes of setting this portfolio on a stronger performance course.  As with many of the other ITA portfolios, I am taking a cautious approach and that is the reason for setting Trailing Stop […]

Bethe Portfolio Review: 23 May 2025

May 23, 2025 By Lowell Herr 2 Comments

Bethe is another portfolio using the truncated asset allocation model.  A maximum of five Exchange Traded Funds (ETFs) are used to populate the Bethe. The down market this morning resulted in selling shares of VOO and investing in SHV, a short-term treasury.  Erratic tariff threats are once more roiling the stock and bond markets.  I […]

Gauss Portfolio Review: 28 May 2025

May 28, 2025 By Lowell Herr Leave a Comment

Gauss is another portfolio using a truncated asset allocation model or one where very few ETFs are used to populate the portfolio.  In other words – Keep it simple.  In keeping with caution in this uncertain economic environment, I placed a 4.5% Trailing Stop Loss Order (TSLO) under VOO and a 2.0% TSLO under SCHG.  […]

Copernicus Portfolio Review: 2 June 2025

June 2, 2025 By Lowell Herr Leave a Comment

While this review of the Copernicus portfolio occurs in June, the data more appropriately belongs to May.  Take that into consideration as you read this update.  As followers of this portfolio know, this is a passive portfolio that focuses on investing only in U.S. Equities and is limited to large-cap stocks that track the S&P […]

Bohr Portfolio Review: 4 June 2025

June 4, 2025 By Lowell Herr Leave a Comment

As with several other ITA portfolios, capital preservation is of significant importance to the owner of the Bohr portfolio.  As a result there is a willingness to give up potential returns during these uncertain times.  The on again, off again tariff battle is an anathema to business as it interferes with future planning.  Right now […]
