This is going slightly OT but since this is Sunday *and* it's a special weekend .. adding some details for those apparently interested:
1/ the first huge profit making "discovery" was made by mathematically trained
Martin Leibowitz at Salomon Brothers in the 70's - arbitraging bonds along the yield curve. This gave rise to Salomon Bros eminence in Wall St at the time. Conceptually this yield curve arbitrage is elementary math, but you had to be trading bonds to realize the profits.
2/
Ed Thorp, initially an established "pure" mathematician famously applied math to beat the casinos regularly in the 60's, then moved on to the stock market, successfully too. Sadly, now retired he's all in dumb Omaha Buffet's BRK.A
For kicks I've put in attachment his neat intro to Kelly's criteria for optimum allocation of investments in favorable conditions. I must confess, as a mathematician by training, I've done more seat of the pants allocation ("bet more the more certain you are", which is probably quantifiable/ provable .. anyone interested please go ahead do the math formalisation, my todo pile is way too large already)
3/ About
Simons, only the inner circle of partners has access to his "special sauce" fund (it is not scalable presumably) and no one has yet cracked it that I know of. As to copying whatever the rest of his funds do, good luck on that: he employs an army of super smart quants, and my take is that they come up with multiple strategies that can be short lived, but are of course implemented all the time.
Now back to my pile of todos, most fun one is getting the hang of the Travis finger picking - this YouTube video of Paul Davies has me totally sold - the relevance to the investment thread is that it's best to keep your main holdings in TSLA stock (the bass line, possibly moving, aka possibly TSLA LEAPS), and improvise on top with the rest (the melodic line)
