A THEORY EXPLAINING THE VOLATILITY OF SOME SHARE PRICES
The book I just finished, “Investing the last liberal art”, gives a fascinating theory on the share price (SP) volatility in some stocks. I tend to agree with this theory.
The theory starts with the assertion that market participants break down into two broad categories, being fundamentalists and trend followers.
Fundamentalists believe in the concept of an intrinsic value of a stock which is generated from (broadly) the PV of future cashflows or one of its many derivatives, such as PE. Over time the SP will gravitate towards an intrinsic value. The intrinsic value is volatile given the vagaries of the future and the sensitivity to various assumptions. For different stocks the spread of probable outcomes will vary around the central case, some very significantly, say WOW v WBT. Some stocks will have a relatively tight range, others wide.
In this world Alpha comes from having a different view from consensus ie the view embedded in the share price, and being correct. This is the world of the fundamentalist. SP volatility exists in this world, as new information is received, the future becomes more certain and the SP reacts accordingly, up or down. I would describe that as acceptable or rational volatility.
There is another world. That is the world of the trend follower. These folk have no belief in intrinsic values. They may not know what they are, do not care, or think they are irrelevant. Fugazi as one of my old bosses used to say (and probably still does).
Trend followers on the other hand are driven by SP action. A high share price attracts interest and the higher it goes attracts more buyers. The theory goes that the share register churns as fundamentals sell out as the SP rises and the register then becomes dominated by trend followers. I am no expert on their strategies, but it appears they are driven by positive SP performance. “all-time highs” are great and exciting, whereas the fundamentalists see increasing risk. A divergence occurs.
Trend followers may backfill with a story, random facts, to support their views, or whatever but it is of secondary importance. Signs of a share register dominated by trend followers may be, stocks that talking heads say you have to own, it going up, strong share price moves (up or down) on no news or trivial information. Like a herd of gazelles looking at a rustle in the bushes that may be a lion they move back and forth, which leads to volatility.
The risk is that as momentum strategies take little or no view on fundamentals the SP can deviate significantly from intrinsic value. How these guys make many, I suspect, is being able to play the crowd psychology, with the understanding that when the game is up, get out fast. Maybe there will be several headfakes at this. Timing appears to be critical, SP momentum is critical.
The worst thing that can happen is when investors adjust their intrinsic values and follow the SP higher with little other evidence. I have seen this, many times, with all its destructive impacts. As if the SP is proving them correct, no matter how high it goes.
It would be useful if investors would self-nominate whether they are momentum trend followers or fundamentals before they invest and the ASX tracks the movements in the register. We would then see for eg, in the last 3 months 90% of all new buyers are momentum players, they know the ticker and SP nothing else, danger! danger! –that’s a joke BTW, when has the ASX done anything useful for retail investors?
As a fundamental investor, I have found the instances when momentum players control a register, frustrating and confounding. A stock I have sat in for months or years suddenly takes off, I sell at a modest gain only to see the thing 3-10X. Usually, the SP comes down a couple of years later, but quite frustrating. Maybe there is a pragmatic way to play this, separating a fundamental playbook and a momentum playbook, where you are well aware you are skating on thin ice. There are clearly professional investors not afraid, ashamed or whatever at playing the Mo game. I will leave that to people much more skilful than me, that those people exist is certainly true! Lol.
