3 Reasons TREX is Risky and 1 Stock to Buy Instead

TREX Cover Image

Over the past six months, Trex’s shares (currently trading at $52.83) have posted a disappointing 14.7% loss, well below the S&P 500’s 16.2% gain. This might have investors contemplating their next move.

Is there a buying opportunity in Trex, or does it present a risk to your portfolio? Dive into our full research report to see our analyst team’s opinion, it’s free.

Why Is Trex Not Exciting?

Even though the stock has become cheaper, we're sitting this one out for now. Here are three reasons we avoid TREX and a stock we'd rather own.

1. Shrinking Operating Margin

Operating margin is an important measure of profitability as it shows the portion of revenue left after accounting for all core expenses – everything from the cost of goods sold to advertising and wages. It’s also useful for comparing profitability across companies with different levels of debt and tax rates because it excludes interest and taxes.

Analyzing the trend in its profitability, Trex’s operating margin decreased by 3.3 percentage points over the last five years. This raises questions about the company’s expense base because its revenue growth should have given it leverage on its fixed costs, resulting in better economies of scale and profitability. Its operating margin for the trailing 12 months was 22.5%.

2. Free Cash Flow Margin Dropping

If you’ve followed StockStory for a while, you know we emphasize free cash flow. Why, you ask? We believe that in the end, cash is king, and you can’t use accounting profits to pay the bills.

As you can see below, Trex’s margin dropped by 5.4 percentage points over the last five years. If its declines continue, it could signal increasing investment needs and capital intensity. Trex’s free cash flow margin for the trailing 12 months was negative 5.8%.

3. New Investments Fail to Bear Fruit as ROIC Declines

ROIC, or return on invested capital, is a metric showing how much operating profit a company generates relative to the money it has raised (debt and equity).

We like to invest in businesses with high returns, but the trend in a company’s ROIC is what often surprises the market and moves the stock price. Unfortunately, Trex’s ROIC has decreased significantly over the last few years. We like what management has done in the past, but its declining returns are perhaps a symptom of fewer profitable growth opportunities.

Final Judgment

Trex’s business quality ultimately falls short of our standards. After the recent drawdown, the stock trades at 21.8× forward P/E (or $52.83 per share). While this valuation is fair, the upside isn’t great compared to the potential downside. We're fairly confident there are better investments elsewhere. We’d recommend looking at an all-weather company that owns household favorite Taco Bell.

Stocks We Would Buy Instead of Trex

When Trump unveiled his aggressive tariff plan in April 2025, markets tanked as investors feared a full-blown trade war. But those who panicked and sold missed the subsequent rebound that’s already erased most losses.

Don’t let fear keep you from great opportunities and take a look at Top 5 Growth Stocks for this month. This is a curated list of our High Quality stocks that have generated a market-beating return of 183% over the last five years (as of March 31st 2025).
