Quote from Daal:
Monish Pabrai provided a great example, he took comfort in sayings like 'volatility is not risk' from Buffett, so he kept buying a bunch of high vol stocks that the market was uncertain about, he got killed in a number on them(He trails the market since 2007 by several basis points). The market was right and whatever he was using as measure of 'true risk' was wrong. When the person is not a genius like Buffett this will happen MUCH more often than not so therefore when the market tells them something is "risky" they better pay attention even if the gurus tell them not to.
The fact that this simple point was argued against it was surprising to me, I thought it was common sense
Is there a trade idea here?No but if I the trader can't get the basics right then he will get a lot of other stuff wrong too
Now see this is what I'm saying. I think this is an interesting conversation / worthwhile topic of discussion, and was enjoying it before some peeps started getting all butthurt, and other peeps started hurling accusations of writing too much and dick-measuring.
Pabrai is an interesting case. I have a close friend of the classic value investing school, and he introduced me to Pabrai's book, "Mosaic," around the time it first came out.
My initial reaction to Pabrai's book -- and the guy was being touted as a new Buffett at the time -- is that "this guy is not NEARLY as smart as he thinks." There were all kinds of glaring red flags in Mosaic.
For the record, you can find my 2006 book review of Mosaic on
this Amazon review page, in which I said, quote:
I was disappointed by a few glaring instances of sloppy thinking here and there. For someone who vigorously highlights a commitment to latticework and the use of multidisciplinary thinking, some of the assertions in Mosaic were a bit breezy, with one or two real howlers thrown in. I do not highlight them because they indelibly mar the book, but because they were so surprising in an otherwise thoughtful text..
Pabrai's next book, The Dhandho Investor, was even worse. While I found Mosaic "worthwhile," Dhandho Investor was just a slopfest. Again the raw concepts were interesting, but the errors were so glaring... after reading Dhandho Investor, I emailed my value buddy and said "I wouldn't invest a penny with this guy."
My point here is two-fold:
1) Quality of thought process matters! An instance of sloppy thinking is like seeing a cockroach in the kitchen... there is rarely just one, and if you see multiple instances you know there's a problem.
2) The bad performance of Mohnish Pabrai is not indicative of the idea that volatility equals risk. Pabrai, like Whitney Tilson, is simply a shitty value investor who enjoyed a temporary moment in the sun.
I also think that a dedicated value investor could learn from guys like Pabrai and Tilson NOT by making vague, handwaving statements like "these guys prove volatility = risk," but instead by looking at their mistakes -- their blowups etc -- and specifically trying to isolate the logic missteps and process failures that created those mistakes.
I still contend that "volatility equals risk" is not a useful statement at all -- it is too vague and more untrue than true in most cases -- and that Buffett was far more right than wrong in his assertion that risk = potential for permanent capital loss.
For the investor or trader seeking to "get stuff right," a deeper understanding is warranted, and that means going below the surface.
Consider, for example, the following statement and question:
When considering a long-term value investment from the perspective of avoiding permanent capital loss, "risk" -- those factors which can facilitate permanent capital loss -- can take many forms. What might some of those forms be?
Then you can start attempting to answer the question, NOT by giving some blanket statement about what "risk" in a value investment or trade is universally, but by building out a list of the various boogeymen that could eat your capital:
* debt levels / credit-based business models that could prove fatal in a sufficiently hostile macroeconomic environment
* loss of the franchise / deterioration of the "moat"
* destructive industry economics (profit margins destroyed by race to the bottom)
* dangerous exposure to raw input fluctuations (commodity price inputs)
* opaque financials / questionable accounting practices
* reliance on a technology that may become obsolete etc.
THESE are the kinds of things that represent "risk" -- i.e. risk of permanent capital loss -- in a long-term investment. The list is by no means exhaustive, that's just some shit I pulled off the top of my head.
But I think it demonstrates how nuance and subtlety are needed in defining what "risk" is, and why Buffett's definition makes sense (for investors) whereas the hand-waving generalization does not. If you invest in a business where the quarter to quarter earnings are volatile as hell but the franchise is impregnable, the economics are rock solid, and the business is a tank that will keep trundling along for decades, volatility is opportunity, not risk.
And of course, for traders, there is a whole other direction / potential list of factors and consideration in determining what "risk" is... but again, flat stating "volatility equals risk" obfuscates more than clarifies.
