What’s the point of a stock split?

What’s the point of a stock split?
Stock splits get headlines, but are they worth it?

Don’t be fooled by headlines Amazon shares are suddenly cheaper now that they’re splitting their stock. They aren’t.

Sure shares will cost one-twentieth of the previous price for new investors (from $2,975 to $149 as of last night's after-hours price).

But for your $149 you’ll get one-twentieth of the profit, cash flow, dividend (that is, if they ever pay one).

For current shareholders, you’ll get 19 new shares for every one you currently hold. They’ll just be priced at $149 instead of $2975, and that makes no difference to the value of your holding.

Past performance is not a reliable indicator of future returns.

So why do it? 

Well, it’s a bit of a gimmick. The only argument for stock splits is they allow people without $3,000 on hand (in Amazon’s case) to become a shareholder. 

A noble cause indeed, but with the advent of fractional shares, it seems an old fashioned argument. 

Amazon says it’s helping its employees offload some hard-earned stock awards. Okay, maybe. If employees needed to transfer their shares to a company offering fractionals, the process can be a bit of an admin headache. So this could be a legit reason. 

Mostly, it seems like an awful lot of hullabaloo.

You might then ask whether Amazon’s management is trying to stimulate some short-term demand in their stock. Whether this is their intention (we highly doubt it) it’s tempting to believe a lower price could lead to more demand. And in turn, this would jack the price back up. 

This might be true. But only in the very short term.

For anyone with a time horizon longer than a couple of months, when it comes to stock prices, it’s profits and cash flow that matter - not supply and demand. 

Stock prices can and do become disconnected from the company’s fundamental reality, but not for long.

Just look at some of the high-flying tech companies whose stock prices became detached from reality last year. That happened because there were more stock buyers than sellers in the post-pandemic boom. 

Most of these stocks have come crashing back down to earth.

There are some investors skilled enough to game short-term demand and supply dynamics, but not many. Most, over time, will underperform a broad index of stocks.

In February, Alphabet also announced a 20-for-1 stock split and its shares have gone sideways since.

So while stock splits garner a lot of headlines, they create zero shareholder value. 

There is only one way for management to create shareholder value and that’s to allocate capital in a way that improves profit and cash flow. 

No amount of stock splitting will achieve that.
