NEW YORK (Reuters) - Rather than waiting to see how the Republican tax bill will fare in Congress, some investors are already picking out gingerly technology, healthcare and consumer companies they expect to use potential tax savings to buy back more of their own stock.

Fund managers from Columbia Threadneedle Investments, Hodges Capital, and SSI Investment Management are among those that are adding to or holding on to their shares of those of companies such as Texas Instruments Inc, Microsoft Co and Southwest Airlines Co in part because they expect to see more share buybacks or special dividends if a tax reform passes in some form.

The House Republican plan would cut corporate taxes to 20 percent from 35 percent and allow companies bring back foreign profits at a 12 percent tax rate, a process known as repatriation. Overall, U.S. companies hold some $2.6 trillion in untaxed offshore cash.

Fund managers say that while it is far too soon to tell whether the tax bill will pass, the prospect of increased buybacks is worth taking a bet on companies that would benefit the most from the plan.

“If you have two companies that you are looking at and one would get a bigger boost from bringing back its cash from overseas, that provides an extra level of return,” said Peter Santoro, a portfolio manager of the $11 billion Columbia Dividend Income fund.

For example, cash-rich tech companies with big international presence, such as Microsoft, are likely to return cash to shareholders via a one-time dividend even if Congress passes a repatriation bill rather than a broad tax reform, Santoro said.

When Congress allowed U.S. companies to bring back foreign profits at a discounted tax rate in 2004, Microsoft issued a special $3-per-share dividend and the Trump tax windfall would likely lead to something similar, Santoro said.

Santoro declined to say whether he was adding to his Microsoft position in recent months. Microsoft is the largest position in Santoro’s fund, according to Morningstar data, and its shares are up 36 percent for the year largely driven by the expansion of its cloud-based business.

Goldman Sachs estimates that the Republican tax bill would increase corporate buybacks by $75 billion, to $590 billion, in 2018. Bank of America Merrill Lynch, meanwhile, estimates about half of repatriated cash would go into buybacks and the rest would get spent on acquisitions and other investments.

Stock buybacks often provide a short-term bump in a company’s share price both by eliminating the total number of available shares and improving metrics such as earnings per share and return on equity.

LAGGING THE MARKET

Yet buybacks, which peaked in 2016, have been slowing over the last three years as rising stock valuations made them more costly and investors have called on companies to invest more in their future by spending on factories or research.

The S&P 500 Buyback Index is lagging the broader market this year after having beaten the S&P 500 by nearly 83 percent between 2009 and the end of 2016.

The Powershares Buyback Achievers fund, which tracks companies that have repurchased at least 5 percent of their outstanding shares over the last 12 months, is up 11.2 percent so far this year, compared with a 15.7 percent gain in S&P 500.

Eric Marshall, a fund manager at $2 billion Hodges Capital, said he has been adding to his position in buyback-heavy companies such as Texas Instruments and Lowe’s Companies Inc because he expects them to increase their current buyback programs if a tax bill does pass.

Texas Instruments, for instance, said in September it would buy a further $6 billion of its own shares, extending a program that has reduced its total number of shares by a quarter over the last five years. Texas Instruments shares make up about 2 percent of the Hodges Blue Chip Equity Income fund. The firm last bought the stock in June, according to the latest publicly available data.

“Buybacks are the most tax efficient thing you can do with your capital, and when you are repurchase your own stock you know exactly what you are buying,” Marshall said.

Ravi Malik, a portfolio manager at $1.6 billion SSI Investment Management Inc, said that a cut in the repatriation rate would benefit convertible bonds in his portfolio such as Citrix Systems Inc, Amgen Inc and Lam Research Corp.

SSI Investment examines its biggest holdings with a significant share of overseas revenues to assess the impact of tax legislation on those companies, Malik said. “That’s how we identified these companies as significant beneficiaries of the changes proposed.”

Barry James, a portfolio manager of the $3.1 billion James Balanced Golden Rainbow fund, said that he expected fund holdings, such as lawn mower maker Toro Co and Southwest Airlines to boost existing buyback schemes should a tax bill pass. Such a move would be preferable to an acquisition or hiring more employees, he said.

“Over the long run, we are fans of companies that reward shareholders, and now is not the right time to find an acquisition cheaply.”
