In the past, I've shared various "indicators" for markets that just don't make sense — like the Superbowl Indicator. The lesson to learn from those indicators is that we crave order, and look for signs that make markets seem a little bit more predictable even where there are none.
Wall Street is, unfortunately, inundated with theories that attempt to predict the performance of the stock market and the economy. More people than you would hope, or guess, attempt to forecast the market based on gut, ancient wisdom, and prayers.
While hope and prayer are good things ... they aren’t good trading strategies.
Today, I want to talk about a still "out there" index, but one that's a bit more practical from an economics standpoint (remember economics ≠ markets). I don't believe it should influence trading decisions, but I do believe it can teach you something about the practical realities of economies.
The Economist's Big Mac index seeks to make exchange-rate theory more digestible. They say it is arguably the world's most accurate financial indicator (based on a fast-food item).
The Big Mac index is based on the theory of purchasing-power parity (PPP), according to which exchange rates should adjust to equalize the price of a basket of goods and services around the world. For them, the basket is a burger … a McDonald’s Big Mac. The difference the disparity in price between Big Macs, and the actual exchange rate lets you know whether the currency is over or undervalued.
According to this measure (as of July 15th, 2020), the most overvalued currency is the Swiss Franc at 20.9% above it's PPP rate. In Switzerland a Big Mac costs 6.50 francs. In the U.S. a Big Mac costs $5.71. The implied exchange rate is 1.14, and the actual exchange rate is 0.94 — thus 20.9% overvalued. For contrast, South Africa Rands are the most undervalued (67%) with a Big Mac costing 31 rand and an actual exchange rate of 16.67.

The index is supposed to be a guide to the direction in which currencies should, in theory, head in the long run. It is only a rough guide, because its price reflects non-tradable elements such as rent and labor. For that reason, it is probably least rough when comparing countries at roughly the same stage of development.
It is not meant to be the most precise gauge, but it works as a global standard because Big Macs are global and it's lighthearted enough to be a good introduction for college students learning more about economics.

Do You Agree to These Terms?
One of the biggest lies on the internet (and there are too many lies to count) is "I have read and agree to the terms of service(ToS)."
There is a plug-in that might help.
Terms of Service Didn't Read has summaries of most ToS, ratings for their user-friendliness and a browser plug-in so when you're about to sign one you can make sure it's safe.
Unfortunately, many of the ToS tell you that they're going to use your data, sell it to spammers, etc. For example, I talked about how a shadowy Russian company was behind FaceApp and owned the rights to photos you uploaded.
Luckily, not every clause in a ToS is legal, and won't necessarily hold up in court - but that doesn't mean you shouldn't be protecting yourself.
So, check out TOSDR, it's not perfect ... but it's probably better than nothing.
