I've heard several accounts of Nathan Rothschild increasing his fortune many times over, having received news from an agent named Rothworth that Wellington had triumphed well before the public. The story goes that Rothschild hung his head in the London stock exchange and began selling his British consul bonds, triggering a fire sale which his agents then capitalized on to scoop up bonds at a fraction of their value, making him a fortune when news of Wellington's victory was known.

However, other sources have said that the increase in wealth occured mostly between 1818 and 1823, due to his having financed the war effort itself, and was the result of a slower and more long-term investment.

I am having trouble finding primary sources to this effect- wouldn't there tend to be recordings of stock transactions? In any case, which is believed to be more true, and how did the story of Rothworth come about if it is not? Thank you all for your help, and I am sorry if I've breached etiquette or subreddit rules, or if the information could be found in a previous thread. I am excited to make my first post here.
