“Be fearful when others are greedy, and be greedy when others are fearful.”
— Warren Buffett, The New York Times, 2008
Companies that keep issuing new shares tend to keep falling as each round adds supply.
Small issuers are hard to borrow; a big contract or takeover can turn the story.
A second (or later) convertible-bond or rights issue within 12 months → short vs the market for 40 trading days from the next day.
