Hey Nishant,
By combining P/B and Div Yield into one variable, you’re essentially getting the same inference with one variable.
I think your first point about equities getting richly valued when this ratio goes over 4 seems correct.
But what’s your definition of backing out of stock market? Is it selling all your holdings?
Regarding point 2, not sure if you’ve checked but this ratio has been under 1 for probably 1-2 years out of the past 16 years. And it’s stayed under 2 for roughly around 4 years out of the 16. So I don’t agree with the 2nd inference as this is a very rare occurrence.
Also I’m not really sure about the 2nd point itself as most of us look to buy individual businesses. At any given point in time apart from extreme overvaluations, the market offers enough decent capital allocation opportunities without having to wait for point 2 to be true.
My only aim of this exercise was to understand when I should refrain from fresh allocation to equities and try to identify those times of extreme overvaluation. Thus, as per my inferences (my original post) when 1,2,3 is true, I believe all of the potential good opportunities in the market at that moment will also correct if not collapse with the other businesses. Plus, any market crash will also throw up multiple more opportunities to invest in.
However, this also doesn’t mean I’m trying to time the market as I believe no one can ever do that consistently for a long period of time. My investment aim is to buy good businesses for very long periods of time if not forever. Thus I want to try and make the optimal (read as roughly correct than precisely wrong) decision of when to buy.
Btw just on high valuations, a lot of quality mid-caps seem to be around that. I’d be very surprised if the mid-cap index outperforms the large-cap this year as well. Some quality large-caps are really begging for people’s attention at the moment.
Regarding the data source, you’re correct the only source for this is the NSE site and I’ve taken the data from there. That’s strange, I got no server restrictions when I downloaded it a few months back. I’ve downloaded the data for all the years and put it into a single spreadsheet. I’m not able to upload it from my iPad (Apple fail ), will share it once I use my laptop or can email to you separately.
PS: Great reply to Satish’s query. Could not have worded it any better myself
