if I gained 50%, 44%, followed by a 53% loss with a 2% fee, I'd be under water for the last 3 years, but the sp500 would have yielded me a 37% gain - virtually no fees. I'd rather the sp500 over these guys


This is the point Nassim Nicholas Taleb makes in his book Fooled by Randomness. In a long enough timeline luck plays a big part in performance. People or firms like Melvin can perform well in a short timeline but when you stretch the timeline out the reality becomes clearer.


This reminds me of a metaphor made by Burton G. Malkiel in “A Random Walk Down Wall Street”. He attempts to give a possible explanation to why there are star traders or funds that greatly outperform the market. It’s something I like to remind myself of from time-to-time.

The metaphor was a coin flipping tournament. You have a bracket of players who flip a coin against an opponent. In each matchup, the player that flips a heads advances to the next round to face another opponent who won a parallel matchup in the previous round. Suppose this is a 100 round tournament, that would mean the eventual winner would have had to flip a heads 100 times to win. You might look at this coin flipper and think they are an extraordinary coin flipper. That they have some innate ability to flip a coin and make sure it lands with the head sides up. In reality, it was just random chance that they flipped the coin correctly, they do not posses any more coin flipping talent than anyone else. They just got really lucky. You can potentially look at a successful hedge fund or trader through this same lens. They have survived the proverbial coin flipping tournament and random chance was on their side.


This was a common investment scam in the past. Create an email newsletter, split it in half and give opposing advice to each side. You then keep ramping up the fees to the winners until eventually they become one of the losers. Once the list gets too small, create a new entity and start again.


I think you'll find it's not a real implementation. OP's example requires 2^100 people ~10^30

It's a similar problem with the email list.

50+ years ago Scrooge McDuck also had this happen to him. He had a treasure map for gold (In Antarctica I think) which he got conditional on profit sharing and he found gold.

The map sellers ran this scam, sold heaps of different maps because someone would find gold.

I personally don't think Scrooge McDuck was just lucky though.


I think this is the first instance of plot armor protecting exclusively against financial loss.


Either I did not understand it, or this doesn't make sense. If the head flipper moves ahead, then that person, truly flipped 100 heads.

Your example would have made sense, if you talking about the 100 times consecutive winner in a coin flip match, with each match, the winner can be heads or tails.


Good idea, but bad example: a 100 round tournament (single elimination) would require 2^100 humans, that is a 20 orders of magnitude increase!! You could do 32 rounds at most.


What if no one gets tails on a flip?

Is it the first person to first get heads or does it have to be consecutive


I read somewhere that holding s&p for 30 years at any arbitrary period, worst you could was 2x


Yeah equivalent percentage losses cost more than gains.

Starting from 100, if you swing 50% up 50% down you get: 150, 75, 112.5, 56.25, 84.375, 42.18, 63.28, 31.64....

You need a 100% gain to make up for a 50% loss.


Those are net of fees. They averaged over 30% annually over 5 years, net of fees. Investors with them since the beginning received a cumulative total return of nearly 400%. That puts you far ahead of SPY over the same time period.

And of course, the risk profile may be different. Equal returns can be more or less appealing depending on the risk profile.


alternatively, you could invest with arkk and not relying on a fund that shorts a gme 140% :P


Your 37% gain on the S&P is fake.

Yes, the gains are real, but not for the reasons that you think.

The true driver behind that 37% gain is the Fed. They’ve been juicing the market for the past 12 years!

The fundamentals, ie Warren Buffet style investing, has not improved. And the moment that the Fed stops with its market manipulation, is when the S&P will fall.

The play is that, when the government gives you free money, then go long. And ride it until the wheels fall off.
