Let’s be honest, most of us have, at some point, clicked on a stock and been greeted by a flurry of ratios that made us feel like we were back in high school maths, minus the Casio calculator and plus the anxiety.
PEG ratio? NAV? Book value? Sounds more like ingredients in a failed diet shake than actual financial tools. But if you’re going to survive the JSE jungle, and not end up buying junk disguised as a “value pick”, you’re going to need to understand what these numbers are whispering about behind your back.
So, let’s unpack them. No MBA required, just vibes, common sense and a little sarcasm.
PEG Ratio: Is the Price Worth the Hype?
You know the classic P/E ratio, right? Price divided by earnings. It tells you how many times you’re paying for a company’s profits. But here’s the catch, P/E doesn’t tell you whether those profits are growing, dying, or just chilling like your uncle’s side hustle.
Enter the PEG ratio. The Price/Earnings-to-Growth ratio. It’s like P/E, but with a built-in BS detector for growth hype.
The formula:
PEG = P/E ratio ÷ expected earnings growth rate
So, if a company’s P/E is 30 and its earnings are growing at 30%, the PEG is 1. That’s like paying for what you’re getting, fair enough. If the PEG is under 1, you might be looking at a bargain. Over 1? Could be overpriced, unless the company has Beyoncé-level brand power or is sitting on a goldmine. Literally.
Think of it this way: if P/E is how expensive your Uber is, PEG tells you whether there’s load shedding on the route or not. One tells you what you’re paying, the other tells you if it’s worth it.
NAV: The “What’s It Really Worth Without the Instagram Filter” Ratio
Net Asset Value, or NAV, is one of those terms that sounds complicated but is basically just the company’s version of “if I sold everything I own and paid off my debts, how much would I be worth?”
The formula:
NAV = (Total Assets – Total Liabilities) ÷ number of shares
Simple, right?
NAV is especially useful when you’re looking at companies that have a lot of tangible assets, like property firms. If a company’s share price is lower than its NAV, it might be trading at a discount, like buying a Woolies lasagne with a 50% sticker on it and no expiry date in sight.
Of course, there’s a catch. Some companies trade above NAV because of brand value, intellectual property, or future growth potential. Like Nando’s, the chicken is good, but the sauce is what really sells it.
Book Value: The Accountant’s Version of Reality
While NAV looks at real-world sell-everything value, book value is more of a balance sheet construct; it’s what the company is worth according to its accountants, who’ve been trained to be allergic to optimism.
It’s the value of a company’s total assets minus intangible assets and liabilities. Pretty close to NAV, but sometimes slightly more conservative.
Investors like to use the Price-to-Book (P/B) ratio to see if a stock is undervalued. A P/B under 1? Could be a bargain. But tread carefully, some companies are cheap because they’re circling the drain. Remember, there’s a difference between value and a value trap.
That R50 microwave at the flea market might seem like a deal until it catches fire during its first attempt at warming up pap.
So What? Why Should You Care About These Ratios?
If you’re investing in South African stocks on EasyEquities or whichever platform you prefer, these ratios are part of your due diligence toolkit, your financial flashlight in the investment darkness.
PEG ratio helps you avoid overpaying for flashy growth stocks.
NAV shows you the rough “real-world” value of a company’s assets.
Book value gives you the accounting version of that reality, stripped of hope, dreams, and marketing.
When combined, these give you a clearer picture of whether a stock is a hidden gem or just a nicely packaged turd.

Let’s land the plane, friends.
PEG = Price vs growth. A PEG under 1 is usually a good sign.
NAV = What a company is worth if it liquidates everything.
Book value = The value according to the accountants (cold, hard, and cynical).
None of these should be used alone, but together, they help you see through the smoke and mirrors of flashy share prices.
Because you’re not just buying a stock. You’re buying a piece of a business. And if that business is all talk and no substance, you’ll be the one left explaining your investment decisions at the next braai.
Rather be the oke who sounds like they know what they’re doing, even if you still call it “book valoo.”
