Benzinga has published a guide identifying four companies as top picks in the paper sector. The publication, written by Chetan Shekar, recommends shares in 3M, Neenah Inc, Mercer International Inc, and International Paper for investors seeking exposure to the industry. The guide suggests these stocks may offer financial growth opportunities as public venues such as stadiums, malls, restaurants, and hotels reopen. Paper is described as a cost-effective material for transporting and preserving products in packaging, food and beverage, hospitality, home utilities, corporate, and personal care sectors. Because paper is biodegradable and recyclable, the article notes it has become a preferred alternative to plastics. The history of the industry is traced back to China, where mulberry bark, hemp, and water were mixed to make pulp. The first paper mill in England started in 1803, making paper a highly traded commodity in Europe for publishing books and newspapers. Domtar Corporation was founded in England in 1848 with a focus on pulp and paper. By 1965, the company generated revenue of over $1 billion. Clearwater Timber Company was established in Lewistown, Idaho, in 1900 and became the world's largest white pine mill. For investors considering these stocks, Benzinga advises looking for consistent earnings per share growth, a low price-earnings ratio, and a high volume of shares traded. Earnings per share is calculated by dividing net income by total outstanding shares. The price-earnings ratio helps determine if a company is undervalued or overpriced compared to industry benchmarks. High trading volume indicates liquidity, making shares easier to buy and sell. The article also reviews online brokers suitable for trading these securities, including Interactive Brokers, Plus500, Public, Robinhood, and TradeZero. Interactive Brokers is described as a comprehensive platform for active and global traders with access to over 150 global markets. Plus500 focuses on contracts for difference, noting that 81% of retail accounts lose money when trading these instruments. Public offers a platform for trading stocks, ETFs, crypto, bonds, options, and alternative assets like fine art. Robinhood is highlighted for its commission-free trades and user-friendly mobile app suitable for beginners. TradeZero provides commission-free trades and round-the-clock customer support for active short sellers. The guide concludes by stating that paper stocks offer a broad spectrum of price points to fit various financial goals.
