Now let’s talk about something just as fascinating: how our predecessors actually valued options, long before Black, Scholes, or Merton ever saw the light of day.
At the time, Bachelier was still peacefully enjoying the finer things in life at his father’s vineyard, while Black, Scholes, and Merton weren’t even concepts — not only were they not born, their parents hadn’t even been imagined.
Thankfully, we have a rare and valuable source to guide us — “The PUT-and-CALL”, a book by London trader Leonard R. Higgins.
