The Capital Asset Pricing Model: Theory and Evidence (Digest Summary)

January 24, 2023

https://www.cfainstitute.org/en/research/cfa-digest/2005/05/the-capital-asset-pricing-model-theory-and-evidence-digest-summary QT:{{”
The capital asset pricing model (CAPM) builds on the Markowitz mean–variance-efficiency model in which risk-averse investors with a one-period horizon care only about expected returns and the variance of returns (risk). These investors choose only efficient portfolios with minimum variance, given expected return, and maximum expected return, given variance. Expected returns and variance plot a parabola, and points above its global minimum identify a mean–variance-efficient frontier of risky assets.

The Marvels—And Mistakes—Of Supertall Skyscrapers – The Atlantic

January 1, 2023

Great article. Thought the very intentional “wind shaping” was fascinating (e.g. the “blow through” floors at 432 Park). Maybe we’ll see fins next.

QT:{{”
This didn’t seem unrelated to a lawsuit that 432 Park’s condo board has filed against the building’s developer. The plaintiffs claim that the building is riddled with more than 1,500 defects that have led to leaks, cracks, electrical explosions, and elevator shutdowns that trapped people for hours—as well as “horrible and obtrusive noise and vibrations,” including clicks, creaks, and a trash chute that thunders “like a bomb.”
….
diffusing the suction-filled whirlpools that sway a building as wind whips around its sides. You could notch the corners, like on Taipei 101, which resembles a towering stack of gifts. You could twist the building, like the Twizzler-esque Shanghai Tower. You could taper it to look like the tip of a paintbrush, like the Lakhta Center, or cut out sections to let wind blow through it, like the Shanghai World Financial Center, which is nicknamed “The Bottle Opener.” 432 Park’s designers decided to make it more porous: Every 12 stories, there are two “blow through” floors with cutouts for windows, but no glass. “}}

Weighted Average Cost of Capital (WACC) Explained with Formula and Example

December 4, 2022

QT:{{”
WACC is calculated by multiplying the cost of each capital source (debt and equity) by its relevant weight and then adding the products together. In the above formula, E/V represents the proportion of equity-based financing, while D/V represents the proportion of debt-based financing.

Cost of equity (Re) can be a bit tricky to calculate because share capital does not technically have an explicit value. When companies reimburse bondholders, the amount they pay has a predetermined interest rate. On the other hand, equity has no concrete price that the company must pay. As a result, companies have to estimate cost of equity—in other words, the rate of return that investors demand based on the expected volatility of the stock.

Companies typically use the Capital Asset Pricing Model (CAPM) to arrive at the cost of equity (in CAPM, it’s called the expected return of investment). Again, this is not an exact calculation because firms have to lean on historical data, which can never accurately predict future growth.

Determining cost of debt (Rd), on the other hand, is a more
straightforward process. This is often done by averaging the yield to maturity for a company’s outstanding debt. This method is easier if you’re looking at a publicly traded company that has to report its debt obligations.

Businesses are able to deduct interest expenses from their taxes. Because of this, the net cost of a company’s debt is the amount of interest it is paying minus the amount it has saved in taxes. This is why Rd (1 – the corporate tax rate) is used to calculate the after-tax cost of debt.

When Should I Get the New Bivalent Booster? – The New York Times

September 24, 2022

QT:{{”
Doctors and immunologists said that, in general, people should wait four to six months after immunization to get a booster. Likewise, if you were recently infected with the coronavirus, you might want to wait that same amount of time before getting another shot.

Opinion | There’s Terrific News About the New Covid Boosters, but Few Are Hearing It – The New York Times

September 18, 2022

https://www.nytimes.com/2022/09/15/opinion/covid-booster-shot.html QT:{{”
The White House coronavirus response coordinator, Ashish Jha, said last week that people might consider getting the booster when they get flu shots, which many do in October and, barring a new variant curveball, think of it as an annual shot going forward. That’s fine if people do that, especially since many immunologists say it’s best to wait three to six months after one’s last vaccination or infection, and many people have had recent infections.
