HIRO Indicator Case Studies

Index Trading Example - SPY 

January 24th, 2022

On January 24th, the stock market was down sharply, with the S&P500 (SPY ETF) being down nearly 4% near mid-session (black line, below). It was at that time that the HIRO Indicator started to register large levels of put selling (blue line, below) in the SPY ETF.

Initially this started as one large trade, taking place near 12:30 ET, with a cumulative wave of smaller put sales continuing unabated into the afternoon.

It is just after these put sales begin at 12:30 ET that the SPY ETF makes its intraday low, and subsequently rallies nearly 4% into the close.

We believe that these put sales allow options dealers to close short hedges, which results in buying pressure in markets. The more put sales there are, the more hedges (ie. stock) that dealers must buy. 

SpotGamma documented this session just after the close on 1/24, viewable here.

Stock Trading Example - CLOV 

January 31st, 2022

CLOV, a speculative “meme stock” was up over 11% on the day, boosted by strong call options buying (orange line).

Note that the stock had a straight path higher, until the call options volume stopped - it was a this point that the stock stopped shifting higher, too.

"Today, I did my first trade solely based on HIRO. I executed via some short-dated puts that multiplied in value. I’ve been singing your praises for a while, but this takes it to a whole new level."
