Are Share Buybacks Propping Up the Market?

Share Buybacks

Investors fear share buybacks are propping up an otherwise anemic market and that a slowdown in the current buyback boom could cause the markets to crash. But is that fear well-founded? Stock buybacks increase earnings per share, even if total earnings don’t change, by reducing the number of shares. And since most investors and analysts look at earnings per share rather than total earnings, management can use buybacks to make an earnings drop look better and solid performance look great.

In this article, we focus on the stock buybacks and share GV’s views on the probable impact of buybacks on the market.

The Breadth of the Buyback Boom

Share buybacks hit a post-financial crisis high in 2015. Apple led all companies, spending a whopping $30.22 billion on buybacks in 2015 to mask slowing earnings, but it was not the only company repurchasing shares to boost per-share earnings:

Companies are spending billions buying back their own shares. For the first three quarters, this year’s buybacks have surpassed last year’s as the most since the 2008 financial crisis.

Boom in Share Buybacks

  • Microsoft turned a 1.3% decline in 3Q2015 total earnings into a 3.1% per-share gain by repurchasing just over 3% of its shares over a 12-month period
  • Wells Fargo used buybacks to convert a scant 0.6% increase in total earnings into a healthy 2.9% gain in earnings per share
  • Pfizer’s buyback boosted a 2% overall earnings gain into a 5.3% per-share jump
  • Express Scripts used buybacks to make a 2.8% overall gain into a 12.4% per-share increase

Are Share Buybacks Inherently Good or Evil?

Companies can use their cash to enhance shareholder value in four ways: repurchasing shares, paying shareholder dividends, investing in the company’s future by engaging in research and development or making capital expenditures, or merging with or acquiring other companies.

Buybacks are Common Among U.S. Companies

Stock buybacks are not a novel tool. The vast majority of US companies have repurchased their own shares (see graph below).

Stock buybacks are more popular in US than in Europe for a number of reasons, including:

  • incentives for stock buybacks appear more frequently in the management compensation packages of US companies than European firms
  • activist US shareholders compel boards of US companies to buy back shares
  • US companies place greater emphasis on quarterly earnings
  • outside the US, there is a general preference for enhancing investor value by paying dividends

So contrary to those who might suggest that “this time it’s different,” it’s not unusual to see share buybacks or corporations account for high percentage ownership of the stock market in the U.S.

Distinguishing Between High and Low Conviction Buybacks

O’Shaughnessy Asset Management (OSAM) defines conviction as the magnitude of a company’s buyback program. A company that buys back 5% or more of its shares is deemed to have high conviction, while a company that repurchases less than 5% of its shares is deemed to have low conviction. OSAM concluded that 70% of the current share buyback boom have been by low conviction companies – just three percent more than the long-term average of 67%. Thus, we’re not seeing a huge jump in buybacks by low conviction companies, but high conviction companies are engaging in buybacks at historic levels.

O’Shaughnessy challenges the assumption that all buybacks are a waste of shareholder capital − money that could have been paid to shareholders as dividends or invested in future growth is instead used to prop up share prices and boost per-share earnings. OSAM’s research found that the minority of companies that engaged in high conviction buybacks actually created value for investors by carefully buying back their stock when prices were low and by delivering significantly better, more consistent performance going forward.

OSAM’s research suggests that not all buybacks are bad for investors. Moreover, careful analysis of the companies issuing buybacks can signal a potential opportunity for investors. The managers GV hires generally focus on these high conviction companies in their composite strategies.

Capital Expenditures Relative to Share Buybacks

Recent updates from JP Morgan Asset Management show that while share buybacks and dividends per share are high, companies have been reinvesting as well:

These high capital expenditures demonstrate that companies are enhancing shareholder value in multiple ways – by increasing dividend yields, reinvesting in the company, engaging in mergers and acquisitions and stock buybacks – not just propping up prices by repurchasing shares.

Using Debt for Share Buybacks

Many low conviction companies that are issuing debt to buy back shares, a practice which could cause trouble should interest rates rise. Investors are concerned that stock prices of these companies could fall as a result of high debt levels. This concern is lessened by the fact that corporate coffers continue to be at high levels. In May 2016, Bloomberg reported that S&P 500 companies had more than $860 billion cash on hand (excluding financials). While debt levels might be elevated in this low rate environment, the high cash levels provide comfort that the companies have a sufficient cushion to repay debt, fuel growth or weather unexpected crises.

O’Shaughnessy also ran some data to look at the change in the debt level of companies in the last 12 months (through March 31, 2016). Their analysis showed that companies which had a high shareholder yield (total of dividend and share buyback yield) had only 5.09% growth in debt to equity. Companies which had less than 5% shareholder yield had a 15.55% increase in debt to equity levels. This data suggests that selective analysis is required when looking at share buybacks as not all companies with high share buybacks have high debt levels.

Share Buybacks are Tax Efficient

The tax structure also affects share buybacks. An increase in the US federal tax rates on investment gains and income has lowered the popularity of dividend payouts and not surprisingly, increased the popularity of share buybacks within the US. While we are certainly not tax experts, generally speaking, dividends are taxed as ordinary income; they do not enjoy the lower capital gains rates wealthy investors desire. (In the interest of full disclosure, some qualified dividends may be taxed at long term capital gain rates, too.) When companies declare dividends, investors have to pay the tax in the year received, regardless of the current rates or the investor’s specific circumstances. Buybacks give the investors the flexibility of choosing the timing of their share sale and the respective tax consequence. Europe’s tax laws are different, and the demand for income obliges European companies to issue more dividend payouts and fewer share buybacks.


Share buybacks aren’t always done for the sole purpose of propping up share prices or earning management incentives. Share buyback programs can also be used for other, investor-friendly purposes:

  • to show the board of director’s confidence in the company;
  • to send a signal to the market that the company’s stock is undervalued;
  • to reflect the lack of other viable investment opportunities for the company;
  • to enhance shareholder value in a tax efficient way.

That being said, stock buybacks motivated by management’s own interests or used as a short-term tactic can be detrimental to shareholders and can easily backfire. Share buybacks can increase company value in the eyes of the market and its shareholders when done to return capital to shareholders. On the flip side, they can destroy company value when done with high debt levels to increase short-term price.

As is often the case in investing, share buybacks defy simple categorization. Careful analysis of share buybacks is critical in examining the decision to invest in the company.
