The Peter Lynch Growth screener listed four companies with high business predictability and at least two more positive investing signs than severe warning signs: Allegiant Travel Co. ALGT, Big Lots Inc. BIG, Mednax Inc. MD and Amerco Inc. UHAL.
Brief overview of Peter Lynch Charts and Warning Signs features
GuruFocus provides two key features for each company: the Peter Lynch Chart and the warning signs. The former compares a company’s historical price trend to the Peter Lynch earnings line, which assumes a price-earnings ratio of 15. Figure 1 shows a sample Peter Lynch chart for Apple Inc. (AAPL).
Figure 1
As Figure 1 illustrates, the Peter Lynch charts shown on a company’s summary page include not only the standard Peter Lynch earnings line, but also the earnings line based on a company’s 10-year median price-earnings ratio.
The summary page also lists the company’s good signs and warning signs under the “Warning Signs” section, as Figure 2 illustrates.

The website color codes the warning signs like those seen on traffic lights: green represents good signs, orange represents medium warning signs and red represents severe warning signs.
Allegiant Air
Las Vegas-based Allegiant Air provides low-cost travel services primarily to leisure travelers in underserved cities, allowing the company to sell air transportation either on a stand-alone basis or bundled with other travel-related products and services.
Allegiant Air CEO Maurice Gallagher discussed in his May 2018 shareholder letter that the company had “61 quarters of consecutive profitability,” including the quarter ending March 31. Passenger revenues increased 14.1% year over year, driven primarily by a 9.5% increase in departures and a 2.9% increase in the load factor.
GuruFocus ranks Allegiant Air’s profitability 8 out of 10 and lists four positive investing signs, including expanding operating margins and consistent revenue growth. The company has a business predictability rank of five stars and profit margins that outperform over 83% of global competitors.
Big Lots
Columbus-based Big Lots offers a wide variety of merchandise at discount prices. Products range from food and consumables to home products and electronics.
Even though comparable-store sales declined 3% during the quarter ending May 5, Big Lots still expects fiscal full-year adjusted earnings to increase between 5 cents and 25 cents from the prior year.
GuruFocus ranks Big Lots’ profitability 8 out of 10, driven primarily by a strong Piotroski F-score of 7 and a four-star predictability rank. The company has six positive investing signs, including consistent revenue growth and a price-sales ratio near a three-year low.

Amerco
U-Haul parent Amerco provides trucks and trailers for “do-it-yourself” household movers. The Nevada-based company’s profitability ranks 8 out of 10 as profit margins and returns outperform over 87% of global competitors.
