To attempt to distill market and industry conditions may welcome oversight of key economic factors. Still, economic factors may share a universal hierarchy, on which they are stratified according to importance. To claim that a certain factor of economic circumstances is unimportant is elementary, although to discern the different extents of these factors’ influence is valid.

Economists cite various measures in delivering sentiments about the economy, including the unemployment rate, inflation rate, interest rate, and supply-and-demand. The multifarious nature of economic analysis cannot be discounted, although perhaps a chief economic force can be established.

While its condition is interdependent with other market forces, this factor is supposedly chief because – amongst all economic factors as they exist independently – it most comprehensively reflects market conditions.

This begs the question: What is this principal economic force that, when scrutinized on its own, provides the most thorough indication of the state of the economy?

Consider the weighted average cost of capital or WACC, for short. This metric evaluates the benchmark rate of return a company must achieve in order to appease its investors.

The precise means of determining a company’s WACC is complex and irrelevant in this context, although, notably, WACC encompasses both debt and equity financing and accounts for the proportion of debt versus equity on which a company depends to finance its assets. Put more simply, WACC indicates the cost of debt and equity financing, proportionally.

Whether WACC is high or low can be construed as a signal of investors’ risk assessment. In other words, a high WACC oftentimes suggests that investors perceive a risky investment, whilst a low WACC oftentimes suggests that investors perceive a more stable investment. WACC, essentially, exists in accordance with the common investor’s perspective.

Unlike subjective alternatives such as general speculation, WACC is, in a way, the most objective gauge of the prevailing investor’s sentiment. Market circumstances are likewise inferrable by WACC data.

WACC pertains to individual company assessments. The weighted average cost of capital is rarely interpreted in the context of the broad economy. Nevertheless, the weighted average cost of capital can be generalized for the standard enterprise in a certain economy by adopting its median value.

In the United States, according to the Harvard Business Review, WACC for companies affiliated with the S&P 500 lied just short of 6% in early 2022. A relatively low figure, the S&P 500’s 2022 median WACC reflects the pandemic-driven economic downturn which preceded it in recent years prior — during which interest rates were lower, reducing the cost of debt. In the case of the aforementioned WACC, the metric accurately corresponds to economic conditions.

But why can WACC be chief, beyond being a merely beneficial economic indicator?

The economy is much a feedback loop system. The intrinsic state of the economy provokes responses from investors. Those responses, which can also be deemed “investor behavior,” consequently dictate market circumstances. In other words, the trajectory of the economy is as much a subjective, psychological outcome as it is a traditionally-logical one.

WACC, unlike fixed interest rates or moving unemployment rates, provides a more direct, intelligible capture of investor sentiments and forecasts – and where they perceive risk, and where they do not.

One may rebuttal that, although a correlation between WACC and investor behavior may be recognizable, investor sentiments are not directly accounted for in a metric generated by a fixed formula, like WACC.

Investor perception is however embraced by this fixed formula. The cost of equity, for example, is determined in part by the market risk premium: the expected market return minus the risk-free rate.

Expected market return, although an output of legitimate projection methods, is a more subjective assessment than other constituents in the WACC equation. Therefore, to a noteworthy degree, psychological factors underlie the weighted average cost of capital.

Unlike interest or mortgage rates – both of which are often cited to form economic conjectures – WACC is neither a reflection of the Federal Reserve’s perception nor a reflection of Freddie Mac’s perception. Instead, WACC may largely be a reflection of the common investor’s perception.

Nonetheless, WACC-based conclusions should be derived reservedly. A high WACC does not necessarily imply that investors demand higher returns due to awareness of stronger risk. Likewise, a low WACC does not necessarily imply that investors demand lower returns due to awareness of weaker risk. Simply put, WACC can be examined more as a psychological evaluation than can other metrics.

For the individual who bears the notion that the economy is more prone to investor psychology than is typically assumed, the weighted average cost of capital can be chief. At the very least, however, WACC cannot be overlooked, as its holistic composition renders it a highly-unique metric.
