What does it mean for issuing corporations to “crank out expensive shares when markets are frothy … and issue debt when markets are cheap”?
crank out expensive shares when markets are frothy Corporations go public (sell their shares for the first time) in market conditions that have a lot of liquidity (a lot of people buying shares) and when they have to make the fewest concessions to appease an investing public. When people are greedy and looking to make money without using too much due diligence. Think Netscape's IPO in 1995 or Snapchat's IPO in 2017. They also issue more shares after already being public in similar circumstances. Think Tesla's 1 billion dollar dilution in 2017. Dilution results in the 1 share owning less of the company. So in a less euphoric investing environment, share prices go down in response to dilution. See Viggle's stock for an example, if you can find a chart. issue debt Non-financial companies create bonds and sell bonds. Why is that surprising to you? Cash is cash. This is called corporate bonds or corporate debt. You can buy Apple bonds right now if you want from the same brokers that let you buy stocks. mutual fund investor Bernstein is making a cynical assessment of the markets which carries a lot of truth. Dumping shares on your mom's 401k is a running gag amongst some financial professionals. Basically mutual fund investors are typically the least well researched or most gullible market participants to sell to, influenced by brand name more than company fundamentals, who will balk at the concept of reading a prospectus. Financial professionals and CFOs have more information than their investors and can gain extended advantages because of this. Just take the emotions out of it and make objective assessments.
