Grandluckmeister: Nothing amazing here for those who understand statistics. It’s only amazing to those who have no concept of randomness. Look at that equity curve at the bottom: only 6 negative quarters in 31 years although this is a random result. If you have a sufficiently large population of fund managers, a few lucky ones will always emerge by virtue of randomness. I will not be surprised to see a random result with no negative quarters either. It’s just statistics.
PAL: But there is a widespread notion that consistent returns require some edge.
Grandluckmeister: Consistent returns may be due to edge or luck. Luck is also some variant of edge. Some people are just lucky.
PAL: In most interviews I have read, fund managers claim to have achieved their performance through the use or fundamental analysis, technical analysis or even some combination of both.
Grandluckmeister: Of course they do not lie about using those methods but overestimate their impact on their results. Both fundamental and technical analysis suffer from confirmation bias and are essentially random trading methods. In the markets causalities and even associations of price action are hard to establish.
PAL: Are you saying that everyone is fooled by randomness in the markets and survivors, especially the lucky ones, attribute their success to their skills although in reality they were just lucky outliers of a random process?
Grandluckmeister: You got it!
PAL: There are so many good books written about fundamental and technical analysis. Do you think then people are wasting their time reading them?
Grandluckmeister: I am not to say what people should or should not do. But they must understand that the associations made between economic data and stock fundamentals are very weak, or even random. For example, why are people buying stocks paying 25 or even 40 times earnings? The ceiling could have been set at 10 or even 5. There is no clear association between the performance of the stock market and the economy. The latter is real world, the former is speculation, greed and fear.
PAL: What do you think about quants and quant funds?
Grandluckmeister: This is something new and we need to have more data to assess the performance. In my opinion most quant funds are not using any real edges but only to fit their formulas on market data. They may get crushed at the end by randomness. Some lucky guy that tosses a coin on the other side of the trade could be the winner. Also note that markets have gotten more efficient and alpha is hard to extract.
PAL: So what is an edge?
Grandluckmeister: Edge has two components: initial luck to build a track record and then large AUM.
PAL: Could you elaborate a little on this?
Grandluckmeister: If you are lucky to build a cushion for a few years then you can grow AUM and trade size. Squeezing out of the market weak hands and profiting from then becomes easier. You do not need any other edge. All these good people with large funds that have outperformed the market are maybe overestimating their skill while underestimating the effect of purchasing power.
PAL: Are you saying that large AUM is the only true edge?
Grandluckmeister: You got it!"
