Stop-Loss Orders and Portfolio Risk

By |2020-06-10T18:59:50-08:00June 10th, 2020|Risk Reduction, TIA|

Stop-Loss Orders & Portfolio Risk Investors hoping for gains through investments in the stock market must naturally bear the risk that the value of their holdings will fall. Prudent investors seek to construct and manage their portfolios in such a way that they bear only as much risk as is necessary to position them to benefit from potential [...]

Ruminations on Radiation:  How cultural fears of radiation emanate By Jonathan Tiemann, August 2019 In 1984, Gordon Matthew Sumner, better known by his stage name, Sting, broke away from his New Age band, The Police, and began to perform and record on his own. His first solo album, released in mid-1985, was the fancifully-named The Dream of the Blue Turtles. [...]

Are Banks Necessary?

By |2018-12-20T20:21:54-08:00November 29th, 2017|Banking, California History, Crypto-currency, TIA, Trade & Commerce|

In today's increasingly digital economy, we can get through our day without ever having to touch cash, write a check or go to a bank. The question of what "money" is emerges as we consider what the relative advantages and disadvantages are of maintaining all of our transactions through electronic systems. Bitcoin poses yet additional challenges for those who believe [...]

Just a Little Respect

By |2018-12-20T20:22:20-08:00June 3rd, 2017|Business News, TIA|

Dr. Jonathan Tiemann Barron's, the Dow Jones business weekly, published its annual investor survey of America's most respected large companies this week. I was one of 112 investors responding to the survey. It's important to note that the survey asked what companies we respect. I chose to interpret the question narrowly, recognizing that not every successful enterprise — and not [...]

Dr. Jonathan Tiemann Would it really be possible to replace our existing energy system with renewables? Mark Jacobson, Professor of Civil and Environmental Engineering at Stanford, thinks we can do so by 2050.1  Prof. Jacobson has done an impressive job of synthesizing demographic, economic, and engineering data to develop a formula that seems to show a path toward a fully [...]

A question for Senator Ted Cruz

By |2018-12-20T20:32:39-08:00October 6th, 2015|Congress, Federal Reserve, Fiscal Policy, Monetary Policy, TIA|

We are about three weeks away from the next Republican candidates' debate, but I'm still stuck on one item from the last debate. Toward the end, the moderators cited a Treasury Department proposal to replace the image of Alexander Hamilton on the ten-dollar bill with that of a woman, and asked the candidates which woman they would choose for that [...]

Competition? Oh, the horror!

By |2018-12-20T20:34:49-08:00May 20th, 2015|Business News, TIA|

By Dr. Jonathan Tiemann I’ve written on this theme before, but it bears repeating. As often as we hear politicians, venture capitalists, bankers, corporate managers, and even economists extol the virtues of free market competition, business leaders know better: Competition is bad for business. And every once in a while, one of the designated cheerleaders of American capitalism suffers a [...]

A Stock Pickers’ Market?

By |2018-12-20T20:35:24-08:00April 24th, 2015|Analysts, Financial Institutions, Money Management, TIA|

By Dr. Jonathan Tiemann Pity the poor hedge fund manager. The lead item in one of the many daily “news” emails I received today — this one from Chief Investment Officer magazine — reads, “Don’t Blame the Hedge Fund Managers.” [1] The burden of the item is that it isn’t the funds’ managers’ fault that they performed so badly during [...]

How much austerity is enough?

By |2018-12-20T20:36:04-08:00April 20th, 2015|Economic Indicators, Euro, Financial Health, Fiscal Policy, Government shutdown, international Finance, TIA|

By Dr. Jonathan Tiemann, April 20, 2015 Although we don't hear the word explicitly that often, austerity is very much at the center of economic debate today. In the US, both the Senate and the House of Representatives are working on budget proposals, which would (their sponsors say) balance the Federal budget within a decade. Those proposals would do so [...]

Inverting Management’s Duty to Shareholders

By |2018-12-20T20:36:52-08:00March 23rd, 2015|Business News, Corporate Actions, international Finance, Shareholder Rights|

By Dr. Jonathan Tiemann, March 23, 2015 While we're on the subject of fiduciaries (see the post just before this one), there's another important principal (owner) - agent (person acting on owners' behalf) relationship in finance. That's the relationship between shareholders and corporate managers. The extent of managers' fiduciary duty to shareholders isn't really clear under the law, especially since [...]
