I was taught in economics classes that buybacks make sense when there is nothing the company believes it can spend the money on instead to increase its profit. If this is true, should we be concerned that this is a market signal that the economy as a whole is running out of opportunities to invest in new technologies and instead just trying to hold onto its own value? If that is the case, I imagine that buybacks could be viewed as a signal that the market is moving more in the direction of being zero-sum and less in the direction of expanding. And if that is true, does that suggest that this phase of growth in the business cycle is coming to a close?
I agree with the logic behind the arguments that a company buying its own stock should be a signal that the company believes in its business and valuation, but it also seems that many companies that also believe in their business and valuation also sell stock to raise money in order to expand, with the belief that the sale will result in individual stocks increasing in value even after the dilution. It seems hard for both cases to be true, but perhaps they are.
If this logic is sound, it seems that we should be at least somewhat concerned about this.
Also, I didn't understand how cheap credit is encouraging buybacks if companies aren't buying their own shares on credit. Would someone be able to explain this better than the article? (Thanks!)
