Six ways to pick a stock

Six strategies are competing with pretend money for eight weeks. Three of them think carefully about what to buy. Three of them are not allowed to think at all. The whole point is to find out whether the thinking is worth anything.

Began 24 August 2026. Ends 16 October 2026, in 7 days.

The Sleeper

+1.92%

never thinks · no trades yet · $2,038 of $2,000

Bought one thing on the first day and went to sleep. It owns a slice of the 500 biggest companies in America and will not be touched again until October.

Right now it owns the 500 biggest US companies.

  • Fri 9 Octheld the 500 biggest US companies
  • Thu 8 Octheld the 500 biggest US companies
  • Wed 7 Octheld the 500 biggest US companies
  • Tue 6 Octheld the 500 biggest US companies
  • Fri 2 Octheld the 500 biggest US companies

It has no reasons. That is the point of it.

The Dart Board

-0.14%

never thinks · no trades yet · $1,997 of $2,000

Picks two things at random every Monday and sells them on Friday. It is not allowed to think, read the news, or have an opinion about anything.

Right now it owns Meta and Nvidia.

  • Fri 9 Octheld Meta and Nvidia
  • Thu 8 Octheld Meta and Nvidia
  • Wed 7 Octheld Meta and Nvidia
  • Tue 6 Octheld Meta and Nvidia
  • Fri 2 Octheld Meta and Nvidia

It has no reasons. That is the point of it.

The Rulebook

-0.81%

one fixed rule · no trades yet · $1,984 of $2,000

Follows a single rule decided in advance: buy whatever has gone up the most over the last three months. It cannot change its mind, ever, no matter what happens.

Right now it owns Meta and Microsoft.

  • Fri 9 Octheld Meta and Microsoft
  • Thu 8 Octheld Meta and Microsoft
  • Wed 7 Octheld Meta and Microsoft
  • Tue 6 Octheld Meta and Microsoft
  • Fri 2 Octheld Meta and Microsoft

It has no reasons. That is the point of it.

The Machine

-2.15%

thinks weekly · no trades yet · $1,957 of $2,000

An AI reads the numbers and the news on Monday morning, decides what to buy, and then is not allowed to touch it again until Friday. Nobody checks its work.

Right now it owns Apple, Meta and oil & gas.

  • Fri 9 Octheld Apple, Meta and oil & gas
  • Thu 8 Octheld Apple, Meta and oil & gas
  • Wed 7 Octheld Apple, Meta and oil & gas
  • Tue 6 Octheld Apple, Meta and oil & gas
  • Fri 2 Octheld Apple, Meta and oil & gas

“Rotate out of fading Microsoft into Meta (best momentum + AI narrative), keep Apple, trim oil & gas; ~$1,527 deployed, ~$445 cash.”

Its own warning: All three are long-momentum near highs into a seasonally weak late September; Meta is up 29% in three weeks and priced for perfection with fresh EU privacy-fine risk, Apple is called 'relatively rich' by its own bulls, and oil & gas's short-term…

The Machine, Impatient

+3.99%

thinks daily · 2 trades · $2,080 of $2,000

The exact same AI with the exact same instructions, except it gets to reconsider everything every single morning. The only difference is how often it is allowed to fidget.

Right now it owns Microsoft and oil & gas.

  • Fri 9 Octheld Microsoft and oil & gas
  • Thu 8 Octsold Nvidia; bought oil & gas
  • Wed 7 Octheld Microsoft and Nvidia
  • Tue 6 Octheld Microsoft and Nvidia
  • Fri 2 Octheld Microsoft and Nvidia

“Friday hold-and-flat: keep Microsoft and oil & gas through the session, code flattens at 15:45 ET; no new positions, no reason to rotate that didn't exist yesterday.”

Its own warning: Both positions are crowded trades late in their moves — Microsoft sits exactly at its high with nothing left to re-rate on, and oil & gas's bid rests on temporary supply shocks (hurricane shut-ins, a diesel directive) that reverse the moment Gulf…

The Human and the Machine

+0.07%

thinks weekly, out loud · no trades yet · $2,001 of $2,000

A person and the AI argue about it on Sunday. The AI does the reading and makes a case; the person can overrule it or refuse to trade at all.

Holding nothing right now — all of it is sitting in cash.

  • Fri 9 Octsat in cash
  • Thu 8 Octsat in cash
  • Wed 7 Octsat in cash
  • Tue 6 Octsat in cash
  • Fri 2 Octsat in cash

“Kept the oil and gas position bought earlier that morning and added nothing to it. The trade was sized for a smaller pot of money, and scaling it up was not a decision anyone had actually approved.”

Why three of them are deliberately stupid

If you let a clever strategy loose and it makes money, you have learned almost nothing. Markets drift upwards, so nearly anything makes money in a good month. The question is never did it make money — it is did it beat not trying.

So three of the six exist to set the bar. One buys and holds. One picks at random. One follows a rule simple enough to do on paper. If the thinkers cannot beat a dart board, the thinking was decoration.

The same rules for everyone

All six start with the same $2,000 of imaginary money and obey the same limits, written into the code where none of them can argue with it: three holdings at most, never more than 40% in any one thing, an automatic sale if something falls 7%, and everything sold before the weekend — except The Sleeper, since sleeping is its entire strategy. Fifteen possible things to buy, chosen in advance, and no borrowed money.

What would count as a result

Not which one made the most money. Eight weeks is short enough that luck drowns out skill, and with six competitors one will finish on top looking brilliant purely by accident.

The real question is whether they behave differently at all. Do the thinking ones trade more? Do they flinch in the same week? Do all six drift up and down together — which would mean the strategies barely matter and the market is doing the work?
