The great active vs passive investing debate

This is a huge topic, potentially a bottomless pit. There are deep theoretical arguments one can wade through about the relative merits of each approach. Then there is the more practical approach of picking out examples, or reflecting on your own experience of trying to pick stocks or time the market. It’s hard to know where to begin, but let’s try to lay down some thoughts on this.

Efficient Market Hypothesis

Starting with the theory, most economic doctrine is underpinned by this EMH premise, which makes a lot of assumptions about rational behaviour, perfect information, etc. Basically everything is already in the price thanks to the efficient market. If you believe this, then it leads towards a passive index approach, because there is no value arbitrage to be monetised via active investing.

I don’t believe markets are efficient in this sense. You just have to look at the bubbles and crashes to see that the level of price variation goes far beyond the movement in fundamental asset value. Largely this is because of human behavioural aspects, e.g. fear and greed, which defy the assumption of rational behaviour. So then, does that make me an active investor ? Well not really nowadays, but I have certainly tried over the years. Basically I evolved to the view that it is possible, but not easy, to beat the market. A safer and more reliable approach is to simply accept market returns, focus on asset allocation and minimise costs whereever possible.

Follow the smart money

It’s funny to hear phrases like this. I thought all those $20 notes were the same, but apparently some are smarter than others. And then there’s the “dumb” money going into passive index funds. Diworsification, as some traders/investors/fund managers might mock. You hear comments like “why would you want to buy the index when it means you’re going to own BHP / WOW” (or in the past it would’ve been TLS, or whatever company/sector is out of vogue). I don’t really buy into these arguments. Call me cynical, but if someone really had an investing edge to sustainably beat the market, then they should be smart enough to use it to their own advantage and bet their own money (with leverage of course). I guess most of them must hope for healthy overall market performance in which case many investors will gloss over the issue of performance vs benchmark and fees.

There is one glaring case that deserves a special mention. This of course is Warren Buffett and Berkshire Hathaway. Surely this must be the poster child for active investment. But is he the exception rather than the rule? Statistically you would have to say so.

Stock picking and market timing is foolish

At the other end of the spectrum, you will hear index advocates pan active investing as foolish and pull out any number of statistics to support their view. You will read a lot of this especially if you hang around bogleheads, MMM, etc forums. While I have gravitated towards this end of the spectrum, I am certainly not in this camp either. As I said already, I believe it is certainly possible to beat the index, just not easy. However for those who have the interest, desire and mindset, I think it certainly is a valid approach to pick stocks and/or time the market. Some of the biggest investment opportunities I have seen in my lifetime have been during market crashes (2002/3 Iraq war, 2008 GFC). If you had the temperament and conviction to buy when everyone else was running for cover, then these opportunities (that will come up a handful of times in your life) are huge shortcuts to FF. Of course, the opposite is also true. If you don’t have the temperament and discipline, then you will end up buying the bubble and selling the crash, which is a great way to extend your working career. I will say it again, it’s not easy to beat the market. One might think bottoms and tops are easily spotted on a chart, after the fact. They are much harder to see at the right end side though. And further to this, even if you can pick the top/bottom, will you have the conviction to trade it.... Or will you lose your neutral, unemotional view and get caught up in the fear/greed like most others ? I’m convinced the mindset factors are critical to success. Unfortunately human beings seem to be hard wired to fail at speculative investing. As I read somewhere, you need to reverse your natural instincts. Learn to be fearful with your losing trades (cut loss) and greedy with your winners (let profits run). Most people are fearful with their winners (worry about giving up gains / being “wrong”, take profit early) and greedy/stubborn with their losers (hold on and hope, usually as losses get magnified).

So far I’ve been talking market timing but how about stock picking - can one even hope to compete with the army of market analysts out there ? At risk of sounding like a broken record, I think it will be tough. Even to find the time to read all the annual reports and company disclosures nowadays is a challenge. Also one of the key drivers is the quality of management. Is it possible to really judge this as an amateur investor who will never be granted a private audience with the CEO and management team of a listed company ? It really takes skill and effort to succeed here, but again, I’m sure it’s possible. Personally if I had to pick one or the other, I would choose market timing as a better chance of success, purely because of the market cycles of fear and greed that you can try and gauge (provided of course that you can remain adequately detached yourself!).

Willingness, capability and need to take risk

I think that’s a quote from the bogleheads, and something I’ve found quite instructive. For me, nowadays, there is not much need to take risk. Therefore I’ve kind of ended up ditching any thoughts of active investing. Even though I believe it’s possible and I have an interest in the area, why bother if there is 1) no need and 2) bearing in mind my view that it’s not easy to achieve a positive result. If I was starting out again, or still on the journey to FF (i.e. 1) does not apply and there is a need), I guess I would be tempted to give active investing a try. It is yet another “shortcut to riches” that I have written about before. But I hope ultimately I’d have the sense to follow my own advice and stick with the boglehead approach, which I have now broadly adopted (although not in a religious way). Nearly all of it resonates with me, especially the part about minimising costs (why pay for your fund manager’s Ferrari). I think investors are spoilt nowadays to have index ETF’s with such negligible fees. Really when you think about it, having the opportunity to invest in 100’s or 1000’s of companies with a relatively small amount of capital and paying <0.2% p.a. Most people would be best served to be thankful for such facilities. Just take this easy option and find a less costly hobby. Old habits die hard though, and on the market timing front, I haven’t entirely given up : I am holding a decent cash allocation and hoping I will have the courage to “fill my boots” should another serious market panic arise in the coming years. I do slightly regret missing the previous few opportunities I’ve had in my investing lifespan.

Active investing

I’ll just finish with a few thoughts on what it might take to succeed as an active investor. As already stated, I’m not an active investor myself so take it for what it’s worth...

Firstly, should you DIY or delegate to a fund manager ? I think it depends on your capability, interest and approach. In most cases, it will be better to use a fund manager. And if you DIY, you should mentally consider it as though you are employing yourself as a fund manager. Sounds a bit silly/contrived, but basically you need to have two hats, one as the investor and another as the fund manager who works for the investor. This fund manager should prepare an investment plan, quarterly reports to review results and actions taken. The investor could even pay the fund manager (a notional payment of course, it’s all your money afterall) a fee of say 1% of funds under management, and see if this fee is recovered or even outperformed. Basically the point is you have to treat it like a pro. If you are going to be an amateur / hobbyist, then either don’t do it (use an active fund manager or go back to indexing), or keep the percentage of assets low, e.g. 20% max, to minimise the risk to your hard earned stash.
Secondly, if you decide to use an active fund manager, the question will arise of how to pick one. As many researchers have shown, past performance is not a reliable indicator. So I wouldn’t just pick the fund with the best returns last year. Really you are betting on the fund manager’s skill and capability so it makes sense to get to know the fund manager. As a minimum, read their prospectus and market reports. Do they have an active website/blog which gives good insights into their investment approach. Do you understand what they are doing and their strategy to beat the average market return ? Are their fees reasonable ? These are the questions I’d be asking myself. If all else fails, there are some Listed Investment Co’s in Australia and a very notable one in the US that have a long track record of solid performance and reasonable fees. They might be a good starting point for your research!
