0:00 Welcome to another episode of The Money Monies, the podcast for South African retail investors who want to stop feeling like they're drowning in jargon and start navigating the markets like someone who actually knows what they're doing. I'm your host, Jay, and today I'm coming to you from Ethiopia, where we unpacking 3 concepts that sound like they belong in a fancy MBA exam but actually control how the stock market flexes its muscles.
0:25 Market breadth, index weighing and free float. By the end of this episode, you'll know by these matter and how they influence what you see on your investment app. Now pour yourself a strong cup of coffee, because this one's going to be lucky, informative, and unlike the usual family meeting promises I'll actually deliver. Let's start with market breadth. This is basically a measure of how many stocks are playing around in the market moves.
0:53 Think of it like this, if the Jazz Top 40 is up 2%, does that mean everyone's happy? Or is it just a few heavyweights pulling the entire index up, like that one Okino office who does all the work while the rest of the team plays Candy Crush? Market breadth looks at the number of advancing shares versus declining stocks. So if 35 out of 40 stocks in the J's Top 40 are up, that's strong breadth.
1:18 If only 5 are up and the other 35 are sulking in the red, that's weak breadth, even if the index itself is positive. It's like being at a BRA where only one guy brought stake and everyone else has PUP. Technically there's food, but it's not balanced. So why does this matter? Because Britt tells you if a rally has legs or if it's just built on the back of a few big names.
1:42 If not, person processes are pumping while everyone else is sleeping. You've got a very top heavy market. That's like balancing your whole financial future on a dodgy pyramid scheme WhatsApp group. Not ideal. Now we look at index weighing. This is where things get spicy because index weighing determines how much each stock influences the overall index movement. Most major indices, like the JSC Top 40 use market cap weighting. That means the bigger the company's market cap, the more weighted carries.
2:14 So if Naspers sneezes, the entire JC catches a flu picture tug of war team where one guy is Dwayne The Rock Johnson and the other nine are Grade 5 reflects. Who do you think's going to do the pulling? That's the market cap weighting for you. Other types of weighing include equal weighting. Every stock just the same weight, like giving everyone the same size chop at the Bri, even the guy who only brought a packet of ice.
2:41 Price waiting. The higher the share price, the more influence. This is old school, I think Dow Jones, but hardly anyone uses it today because price doesn't always equal size. Then you have fundamental weighting. This is based on metrics like earnings and dividends, which sounds great in theory, but in practice it's like letting your mother-in-law pick your fantasy football team. A little bit risky for US retail investors. This matters because your ETF's performance depends on how the index is weighted.
3:11 If you own a JSE Top 40 ETF, you're basically betting heavily on Nash Process and Richmond because they dominate the waiting. Now, finally, let's talk about free float. This one sounds like a lacquer summer pool party, but it's actually about how many shares are freely available for trading on the market. Not all shares you see in a company's total count are available to you. Some are locked up by insiders, governments or even long term investors who never sell.
3:40 Free float is what's left for the rest of us pledged to buy and sell. For example, if a company has 1 billion shares outstanding, but 400 million are held by the founder and another 200 million by a government pension fund, then the free float is 400 million shares. So why does this matter? Because low free float can make a stock more volatile than a Springbok fan at the Rugby World Cup. With fewer is available, even small trades can move the price dramatically.
4:10 So when you see a small cap stock swing like a DJ at a wedding after too many tequilas, check that free float. Chances are it's still as picking Pi's budget after paying suppliers. So why should you care about all of this? Market breadth helps you gauge if a rally is broad based or just a couple of big names doing all the heavy lifting. Index Whiting explains why some stocks dominate ETFs and indices, so you're not shocked when your Top 40 ETF performs like a nice person.
4:37 Fan club Freeflow tells you how liquid stock is and whether you're walking to a volatile party uninvited. Let's do a quick real world example for you. Take the JSE Top 40 last passion process together can make up more than 20% of the index. So if they rally the Top 40 looks like a year or even if most of the other shares are still snoozing, that's poor market breadth.
5:01 Was a heavy market cap weighting buyers. Add in a stock with a low free float like an obscure mining junior, and suddenly you've got a recipe for chaos. One big buy order and the price moves faster than the Dogecoin in 2021. Now it's time for your stock fell. Start to back off stock lingo for this episode 22. Market breadth is how many stocks are actually joining the party when the market moves.
5:29 More dancers equals healthier market index waiting. Who's really pulling the rope in the index spoiler? It's the big guys. Free float is the shares that are actually up for grabs. The smaller the float, the Wilder the right. Then there you have it folks, another jargon jungle conquered. And while my jokes may have more float than some Jays you small caps, Please remember this is not financial advice. Please do your own research and speak to a licensed advisor and I'll catch you next time on the Money Maize when we have a look at headline earnings versus core earnings write offs and adjusted metrics.
