Stock Market Capitalization To GDP Ratio
Categories: Company Valuation, Econ
Joey’s been asking people how they’re doing for years, but today, he’s going to ask a different question. Today, he wants to know how the stock market is doing. And to answer that question, he’s going to look at something called the “stock market capitalization-to-GDP ratio.”
As its name implies, this ratio uses stock market capitalization and a nation’s gross domestic product, or GDP, to assess whether a particular market is overvalued, undervalued, or, like Goldilocks, valued juuuuust right.
Here’s how it works: we pick a stock market, any stock market. Could be the European market. Could be the U.S. market. Could be the global market as a whole. We take that stock market’s total capitalization and we divide it by the same market’s GDP. Then we multiply that number by 100, and voila: we’ve got ourselves a stock market capitalization-to-GDP ratio. If the number is above 100%, that generally means the market is overvalued. If it’s below 50%, it's generally an indication that it’s undervalued. We say “generally” because the experts disagree on where the lines between undervalued, appropriately-valued, and overvalued are. But if we compare this ratio to a market’s historical averages, we can get a picture of whether that particular market is trending upward, downward, or just staying put.

Finance: How does the economy relate to ...1 Views
and finance Allah shmoop How does the economy relate to
the stock market Generally speaking movements in the stock market
precede movements in the economy Why Well stock market pundits
analysts and gadflies spend all day long staring it data
doing discovery projects poking its supply chains in sniffing with
other canaries in the mine shafts of the business world
detail ng how well or poorly the world's products are
selling and they come to conclusions and then they act
very quickly upon them And a few key data points
have historically been highly correlated with future performance of the
economy Things like housing starts I eat the starting of
builders building new homes the sale of new cars and
the number of help wanted ads in the newspaper or
Craigslist Or indeed or glass door or wherever They're all
canaries in the mineshaft All of them If you see
those numbers move dramatically up or down well then you
know tweet tweet The stock market then presumes that about
2/4 later give or take the effects of that up
or down economic data will be felt in the form
of corporate earnings being either better or worse than predicted
So is you'd guess Not all businesses or stocks or
economies behaving the same way Airlines for example are extremely
reflective of the economy That is when times are weak
The marginal consumer chooses to not go on that family
vacation to Disney World with the all inclusive Minnie Mouse
escort package and some five ten 10 maybe 15% fewer
airline tickets get sold then in that bad economy might
not seem like five ten 10 15% moves or that
big of a deal But since airlines have a huge
fixed recurring cost anyway I eat the airplane has to
go from Denver to Orlando whether or not it's full
than those marginal 27 passengers who chose not to go
on that flight because the economy was soft Well they
don't contribute a dime of revenues Teo South wars their
lines So even a small movement in economic health hurts
airlines Ah lot in their stock prices usually reflect this
move quickly On the other end of the rainbow Liv
drug companies cyber security bank router businesses and early extremely
high growth young companies that have narrowed the number of
clicks for teenagers to find you know art films and
thus with insatiable demand those stocks are almost immune to
economic headwinds Right Got a headache Yeah Well you're going
to pay the nine bucks for the bottle of aspirin
whether or not the economy is good or bad Are
you an online bank with a retail presence Well guess
what then You're either going to pay for the best
cyber defense or wake up one day with all of
your monthly statements having been turned from English tio Cyrillic
So you'll pay whether the economy is good bad or 00:02:49.66 --> [endTime] ah yeah ugly
