Value Traders: Fundamental Analysis and Finding Mispriced Securities (Chapter 16)
Book: Trading and Exchanges: Market Microstructure for Practitioners Author: Larry Harris Publisher: Oxford University Press, 2003 ISBN: 0-19-514470-8
Value traders are the people who do the deep research. They study balance sheets, analyze industries, build financial models, and try to figure out what things are really worth. When they see a stock trading below their estimate of fundamental value, they buy. When they see one trading above, they sell.
But here is the thing most people miss. Value traders are not just speculators hunting for bargains. They are also liquidity providers. In fact, Harris makes a strong case in Chapter 16 that value traders are the ultimate suppliers of market liquidity. They trade when nobody else will.
Value Traders as Liquidity Suppliers
Value trading is only profitable when price differs from fundamental value. And that can happen two ways.
First, new information changes fundamental value before the price catches up. News traders profit here because they get the information first.
Second, uninformed traders push the price away from fundamental value. Value traders profit here. Through their research, they can tell that the price no longer reflects reality. Their buying or selling pushes the price back to where it should be.
So value traders make money specifically by providing liquidity to uninformed traders whose activity has distorted prices. That is a very different way of thinking about fundamental analysis. It is not just about being smart. It is about being the person who steps in when everyone else is wrong or scared.
Here is how it typically plays out. A bunch of uninformed traders want to sell a stock in a hurry. They sell to dealers who offer them immediacy. Dealers accumulate inventory they do not want. They start lowering their prices, partly because they suspect the sellers might be informed, and partly because they do not want to hold such large positions.
Prices drop below fundamental value. Value traders notice. They buy from the dealers at discounted prices. The dealers get their inventories back to normal. The value traders hold their positions and wait for prices to recover. Both can profit from the transaction.
Market Resiliency
Value traders make markets resilient. A resilient market is one where uninformed trading can not push prices far from fundamental value for long. Value traders stand ready to trade whenever prices drift too far, which pulls prices back.
This matters for dealers too. In resilient markets, dealers are more comfortable taking large positions because they know value traders will eventually show up to help them rebalance. Without value traders, dealers would be much more cautious, and liquidity would be worse for everyone.
The Outside Spread
Value traders have their own version of a bid/ask spread, called the outside spread. This is the range of prices at which they are willing to buy and sell. Unlike dealers, value traders rarely advertise these prices. They do not want to reveal their value estimates or give free trading options to the market.
The outside spread is much wider than the spreads dealers quote. There are several reasons for this.
Dealers trade in and out quickly. They just need to discover market values and flip their inventory. Value traders take large positions and hold them, sometimes for a long time, waiting for prices to correct. That means more risk, more financing costs, and the possibility that new information arrives and changes values while they are waiting.
Value traders also spend heavily on research. Their spreads have to be wide enough to cover not just the positions they trade, but all the analysis they do on positions that turn out to not be mispriced. Most securities a value trader analyzes are properly priced. The winners have to pay for all that wasted research on the non-opportunities.
Dealers can earn the full spread on a round trip. The best a value trader can hope for is to earn half the outside spread when the price returns to fundamental value.
The Winner’s Curse
The winner’s curse is one of the most important concepts in this chapter, and honestly it applies to way more than just trading. It affects anyone who competes to buy or sell something with an unknown value.
The basic idea is simple. In an auction for something with common value (meaning it is worth the same to everyone), the winner tends to be the person who overestimated the value the most. You “win” the auction, but you overpaid. You are cursed by your own victory.
Harris gives the example of oil and gas lease auctions. Until companies learned better, they systematically overpaid for leases. The geologists were accurate on average across all the tracts they evaluated. But on the tracts they won, they had overestimated. On the tracts they lost, they had slightly underestimated. They were right on average but wrong on the ones that mattered.
Here is the counterintuitive part. You need to bid more conservatively when competing against many other bidders. Most people think the opposite. They think more competition means you need to bid more aggressively. But if you outbid 50 other people, you probably overestimated value significantly. If you outbid 2 people, your estimate might have been only slightly too high.
And you need to bid more conservatively when values are hard to estimate. Greater uncertainty means bigger potential errors, which means a higher chance of overpaying.
Value Traders and the Winner’s Curse
Value traders face the winner’s curse because they only trade when they believe price differs significantly from fundamental value. If their estimate of value is wrong, they trade when they should not.
They misestimate values when they use the wrong models, miss important information, or misinterpret what they have. These mistakes do not necessarily make them buy overvalued things or sell undervalued things. But the market impact of their trades still costs them. They lose because they traded when there was no real opportunity.
Value traders protect themselves by widening their outside spreads. When the winner’s curse problem is severe, those spreads get very wide.
Harris points out that Internet stocks in the late 1990s were extremely volatile partly because of the winner’s curse. The stocks were hard to value and tons of traders were trying to value them. Value traders needed very wide outside spreads to protect themselves. Prices bounced around within those wide spreads, creating wild volatility.
One useful insight: you do not want to compete against foolish traders. If people are bidding irrationally, you should accept that you will lose the auction. You can not make money bidding against people whose strategy guarantees they will lose money. Many Internet entrepreneurs of the late 1990s learned this the hard way.
Value Traders vs. News Traders
Both value traders and news traders are well informed, but they profit in different ways. Value traders profit when uninformed trading pushes prices away from fundamental value. News traders profit when they learn about new information before everyone else.
They often lose money to each other. Value traders lose to news traders when they mistake a news trader for an uninformed trader. They offer liquidity to someone who actually has new information, and prices move against them. News traders lose to value traders when the information they are trading on is already reflected in the price.
To trade successfully as a well-informed trader, you need to know which role you are playing at any given moment. The two approaches require different disciplines.
As a value trader, you need to be sure you are offering liquidity only to uninformed traders. You should have all publicly available fundamental information and some idea of why uninformed traders are demanding liquidity.
As a news trader, you need to be sure your information is not already in the price. You should know how your information came to your attention, when it first became available, and who else might know it.
The Bottom Line
Value traders are the market’s liquidity providers of last resort. When dealers have reached their limits and will not take more positions, value traders step in. They make markets resilient by ensuring that prices can not stay disconnected from fundamental values for long.
But this service comes at a cost. Value traders need wide spreads to cover their research expenses, their exposure to the winner’s curse, and the risk that news traders will surprise them. Those wide spreads mean that value traders only trade when prices are significantly mispriced. Small deviations from fundamental value do not attract them.
For anyone interested in fundamental investing, this chapter reframes the whole activity. You are not just picking stocks. You are providing a service to the market. And the better you understand that service, the better decisions you will make about when to trade and at what price.
