You may suppose inventory markets’ largest function in financing corporations occurs on the day of their preliminary public providing (IPO).
Though IPO day is necessary to every firm, knowledge means that public markets see extra firm money flows from secondary points, buybacks and dividends.
IPOs are smaller than secondaries
The annual SIFMA handbook at all times contains fascinating knowledge throughout asset courses and nations.
One chart that’s fascinating to me, working at an inventory alternate, is under. It exhibits that IPO proceeds are literally a fraction of all capital raised by the U.S. inventory market annually — even in a “massive” yr for IPOs, like 2021 (observe that the SIFMA knowledge excludes particular objective acquisition corporations, or SPACs).
For instance, final yr, IPOs raised a complete of $30 billion, whereas secondaries raised virtually $170 billion.
Elevating further capital, for brand spanking new acquisitions or initiatives, is one other good thing about being a public firm. Sometimes, secondaries are accomplished in a single day, at a small low cost to the closing value that day.

Buybacks are larger than secondaries
In fact, corporations don’t at all times want to boost capital. Generally they need to return free money circulate to buyers.
A method to do this is by way of buybacks. Based on knowledge from the Wall Avenue Journal, corporations spend round $1 trillion annually on buybacks. That’s considerably greater than the worth of secondary finance raised.
Apparently, different knowledge from Bloomberg means that buyback spending is comparatively concentrated, with the highest 11 corporations accounting for nearly $500 billion of introduced buybacks.

Dividends are related in measurement to buybacks
One other option to return money to shareholders is by way of dividends.
The info under, from Goldman Sachs, exhibits that dividends are related in measurement to buybacks. Importantly, the information additionally exhibits dividends are usually very constant over time.
In distinction, in durations of recession, when gross sales usually fall, most corporations considerably cut back buybacks. That helps them preserve money flows for operations — surviving downturns. It additionally makes buybacks extra cyclical.

Corporations handle financing in some ways
The info exhibits that though IPOs are necessary to every firm once they occur, public markets additionally permit corporations to effectively elevate capital from and return capital to buyers — usually at or close to the prevailing market value.
That’s a crucial manner public markets assist make investing, and asset allocation, much more environment friendly.
