What the Last Ten Months of Market Action Say to A Quant

The goal in quant investing is to use data to shade the odds in your favor. There is nothing magic and nothing guaranteed but if you can get enough bets down when the odds are in you favor, even as low as 51-49, and if you have a big enough bankroll to handle the semi-variance when betting at and above the Kelly optimum* you will end up with a lot of chips.
Here's an example from PastStat:

we are reluctant to make it open source , but anyway , higher highs and more dizzy highs on $SPX 

ten higher highs on $SPX monthly chart

below the trading odds , for the next 1/2/3/4/5/6/12 months, when $SPX makes ten or more higher highs in row, data since 1950
