Ann: 1HFY23 Investor Presentation, page-17

I've done some math - many times actually. That's why this has grown to be my 2nd biggest holding. The math is "simple" - but the assumptions to make are far from easy (and entail a very high degree of uncertainty). One of the surest ways (imo) to get a sense of whether the current price is over stretching future prospects (or not), is to ascertain whether market sentiment is uniformly bullish (or its opposite).

Sentiment from "randoms" is pretty much what "market sentiment" actually is - though yes, the sentiment of 1 or 2 on a chat site may not be representative.
