Extreme Weather Meets Deregulated Power Market in Texas

Latest data indicates that the electricity shortage in Texas was caused by the grid failing due to ERCOT not being able to balance demand and supply of power. Wind generation is not weatherized for extreme conditions, so it was interrupted. Anecdotal evidence and historical experience indicate that Combined Cycle gas was not ready for the arctic weather either.

Factfulness – Facts Matter, So Does Being Aware of Our Bias Against Facts

Factfulness is the collaborative work of Dr. Rosling, attempts to explain the general human condition around the world. It is a statistical therapy to the data enthusiast: Things are not as bad as we think! We are not talking about Northern European optimism, or the wishful thinking of a pep-talker, we are talking about being factful.

Price to Equity Ratio and Growth

As COVID-19 spreads with full speed, the stock prices are doing extremely well. The average price to earnings ratio (PE) of S&P 500 companies is at a historical high level of 37.4. Such are the conditions set up with the zero-interest-rate policy of the US Federal Reserve and zero cost electronic trading that many brokerages offer.

What is wrong with the California Electricity Market?

Even though the marginal cost of electricity generation has steadily decreased, this benefit did not reflect on the electricity bills of California residents. Eagerness of California to incent behind the meter solar generation and mandate RPS standards earlier than other states, increased the average cost of wholesale electricity. We expect that future regulatory adjustments will correct some of the causes of this unintended consequence.

Bayesian Thinking During the Pandemic

It is said that some COVID-19 antibody tests have 40% to 50% false positive rate. How much shall we believe in the results of these tests? In this blog, we will discuss how to interpret new data (test result), and changing our prior belief upon observing new data, the so called Bayesian Thinking.

It took six months from the day that Lehman Brothers failed in 2008 to when the stock market recovery began in March 2009.

Impact of COVID-19 on California Electricity Demand

Two of the primary variable inputs to our modern economy are labor and energy. We are all watching the labor markets and the record unemployment claims week after week. Last month, we also have witnessed, for the first time, negative oil prices caused by disappearing demand. But here I will focus on probably the most important input, electricity. What is happening with electricity consumption while California shelters in place?

Markets In The Corona Virus Crisis - The Great Decoupling Continues

It has been 10 weeks since we started keeping track of the market downturn. Over thirty million unemployment claims have been filed in the past six weeks. April was the best month since January 1987 for the stock market. In short, the great disconnect continues. The disconnect is puzzling many market researchers.

New Light On Old KPIs - Operating Margin

I will devote a few blogs to important KPI’s (Key Performance Indicators) and discuss their meaning in a new light. I have not heard financial advisors talk about these KPI’s in the same simple meaning that I will describe here. Let’s start this week with the operating margin. In these very uncertain times interpreting these KPI’s with a new insight is ever more important.

What Kind of Bail-Out Does Each Company Deserve?

United Airlines (UAL) CEO Oscar Munoz went to Congress and asked for a nearly $60 billion bail-out for the airline industry, accompanied with a thinly veiled threat that if UAL does not get this infusion, it may have to lay off even more employees than it had already planned. Is this the best way the US treasury can spend $60 billion? Are we to choose which airline to save? What happened to the corporate tax windfall that UAL and other airlines got in 2018? Why not ask the banks for a loan?

Markets In The Corona Virus Crisis

In the past few days, several wise people who have seen multiple market crises stated that they’ve never seen anything like this. Vaccine research is fully under way. If this crisis ends with a vaccine it will be much different than the financial crises which required years of massive quantitative easing to recover. Hopefully we will not be social distancing for long.

On March 9, 2020, the US stock market’s favorite index S&P500 fell 7.6%, the biggest daily drop since the 2008 financial crisis. Blame it on the corona virus, blame it on the bad timing of the Saudis and the Russians to get into a price war. The important thing is that it happened …and it wasn’t supposed to.
